How to open file cmdb. File extension CMDB

Have a problem opening a .CMDB file? We collect information about file formats and can explain what CMDB files are. Additionally, we recommend the programs that are most suitable for opening or converting such files.

What is the .CMDB file format for?

File extension .cmdb primarily associated with the ANSYS Meshing (CMDB) format and file type. CMDB is a database format used by ANSYS Workbench applications such as ANSYS CFX, ANSYS Fluent, and possibly other ANSYS CFD software for storing mesh data.

File .cmdb is a mesh definition created in ANSYS Workbench and saved in a database format. The mesh consists of a number of interconnected points that define the geometry of the object. Mesh files are typically saved in the SYS / MECH subdirectory of the ANSYS Workbench project root directory.

Existing mesh files (also with the .mesh dat extension) created in earlier versions of ANSYS Workbench will generally import successfully in newer releases, with a few exceptions for CFX-Mesh mesh files ( .cmdb). ANSYS Fluent uses a different file format and file type (.msh) for mesh files.

Expansion from a completely different perspective .cmdb also assigned to service metafiles generated by some advanced multimedia TVs (eg Samsung) on removable storage devices such as external hard drives or USB drives. File .cmdb(usually paired with a .cm00 12 or other file) contains various metadata collected by scanning the contents of the media and used by the TV to access files, save the current playback position, etc.

Such files .cmdb, .cm00 12 and the like can usually be safely deleted as they will be recreated as soon as the media is reconnected to the TV.

Software to open or convert CMDB files

You can open CMDB files with the following programs:

Yesterday, during the course, I caught a virus on a USB flash drive, which was immediately detected and removed by an antivirus on my home computer. However, it turned out that all folders on the flash drive have become shortcuts... Some time ago I already faced such a problem, so I know the first rule to prevent infection of your computer: do not try to open shortcuts to folders! (even if the data on the flash drive is invaluable, and you want to immediately make sure that it has not gone anywhere). Why shouldn't you open these shortcuts? The creators of the virus went for the following trick: two commands are written in the properties of these shortcuts:

The first launches and installs a virus on your PC
The second opens the folder you are interested in.

Those. a user who does not have an antivirus installed on his computer, not paying attention to the fact that all the directories on the flash drive are now displayed as shortcuts, may simply not know that the flash drive is infected. all folders on the flash drive are opened and the information in them is in place. In some modifications of such a virus, folders stop opening even if the shortcut is clicked. In any case, do not panic, do not rush to format the USB flash drive and read the instructions below carefully. Understand, the catalogs have not gone anywhere, they just lay on the flash drive and still lie. It's just that the virus hid all the folders on the USB flash drive, i.e. they have been assigned the appropriate attributes (hidden + archived). Our task is to destroy the virus and remove these attributes.

So, below I will give instructions describing what to do if the folders on the flash have become shortcuts

Delete executable files of the virus on a USB flash drive

The first step is to get rid of the executable files of the virus. This can be done using any antivirus (fortunately, there are a bunch of free or portable versions, such as Dr.Web CureIt or Kaspersky Virus Removal Tool), but if it is not there, you can try to find and neutralize the virus manually. How to find the files of the virus that infected the USB flash drive?

In this example, RECYCLER \ e3180321.exe is the same virus. Those. a virus file named e3180321.exe is located in the RECYCLER folder. We delete this file, or you can delete the entire folder (I recommend checking the presence of this folder both on the infected USB flash drive itself, and in the system directories C: \ windows, C: \ windows \ system32 and in the profile of the current user (more about them below)).

v Windows 7, 8 and 10- C: \ users \ username \ appdata \ roaming \
v Windows XP- C: \ Documents and Settings \ username \ Local Settings \ Application Data \

If these directories contain files with the extension " .exe", Then most likely this is the executable file of the virus and it can be deleted (on an uninfected computer, this directory should not contain .exe files).

In some cases, such viruses are not detected by antivirus software. they can be created as .bat / .cmd / .vbs script files that, in principle, do not perform any destructive actions on the computer. We recommend that you manually check the USB flash drive for the presence of files with such permissions (their code can be viewed using any text editor).

Now clicking on the shortcut is not dangerous!

Checking the system for virus autorun commands

In some cases, viruses register themselves in the system startup. Check with your hands the following registry branches (regedit.exe) for suspicious entries:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run- these programs are launched when the computer boots
HKEY_ CURRENT_ USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Run- programs automatically launched when the current user logs in

Delete all suspicious entries and unfamiliar programs (you will not do anything wrong, and even if you disable the startup of some necessary program, you can always start it manually after logging in).

Other ways to autorun programs in the system are described in the article.

Restoring the view of directories and access to folders

After the flash drive and the computer are cleaned of viruses, you need to restore the usual view of folders and files on the flash drive. Depending on the modification of the virus (and the imagination of the "developers"), the system attributes "hidden" and "system" can be assigned to the original folders, or they can be transferred to a certain hidden folder specially created by the virus. These attributes cannot be removed just like that, so you will have to use the commands for resetting attributes through the command line. It can also be done manually or using a batch file. Then the remaining shortcuts to folders can be deleted - we do not need them

Manual way to restore the attributes of hidden folders on a USB flash drive

Open the command line with administrator rights
In the black window that appears, enter the commands, after typing each press Enter
cd / d f: \
, where f: \ is the drive letter assigned to the flash drive (in a specific case, it may differ)
attrib -s -h / d / s
, the command resets the S ("System"), H ("Hidden") attributes for all files and folders in the current directory and in all subfolders.

As a result, all data on the drive becomes visible.

Script for automatic removal of hiding attributes from source folders and files

You can use ready-made scripts that perform all operations to restore file attributes automatically.

Download the file (263 bytes) from this site (direct link) and run it with administrator rights. The file contains the following code:

: lbl
cls
set / p disk_flash = "Enter flash drive:"
cd / D% disk_flash%:
if% errorlevel% == 1 goto lbl
cls
cd / D% disk_flash%:
del * .lnk / q / f
attrib -s -h -r autorun. *
del autorun. * / F
attrib -h -r -s -a / D / S
rd RECYCLER / q / s
explorer.exe% disk_flash%:

At startup, the program asks you to specify the name of the flash drive (for example, F:), and then itself removes all shortcuts, autorun. * files, removes the hide attributes from directories, deletes the folder with the RECYCLER virus and finally shows the contents of the USB flash drive in the explorer.

Hope you find this post helpful. If you come across other modifications of the virus that turns folders on a USB flash drive into shortcuts - describe the symptoms in the comments, we will try to figure out the problem together!

How to open CMDB files

If you cannot open the CMDB file on your computer - there may be several reasons. The first and at the same time the most important (occurs most often) is the absence of a corresponding application serving CMDB among those installed on your computer.

The easiest way to solve this problem is to find and download the appropriate application. The first part of the task has already been done - the software supporting the CMDB file can be found below. Now it is enough to download and install the corresponding application.

In the further part of this page you will find other possible causes of problems with the CMDB files.

Possible problems with the files that are in the CMDB format

The lack of the ability to open and work with the CMDB file should not mean at all that we do not have the appropriate software installed on our computer. There may be other problems that also block our ability to operate the ANSYS CFX Mesh Database file. Below is a list of possible problems.

Corruption of the opened CMDB file.
Incorrect links to the CMDB file in registry entries.
Accidentally deleting CMDB extension description from Windows registry
Incomplete installation of an application that supports the CMDB format
The CMDB file being opened is infected with unwanted, harmful software.
There is not enough space on your computer to open the CMDB file.
The drivers for the hardware used by the computer to open the CMDB file are out of date.

If you are sure that all of the above reasons are absent in your case (or have already been excluded), the CMDB file should cooperate with your programs without any problems. If the problem with the CMDB file has not been solved, it may mean that in this case there is another rare problem with the CMDB file. In this case, only the help of a specialist remains.

How do I associate a file with an installed program?

If you want to associate a file with a new program (eg moj-plik.CMDB) you can use two options. The first and easiest is to right-click on the selected CMDB file. From the open menu, select the option Select default program " then option "Revise" and find the required program. The whole operation must be confirmed by clicking the OK button.

Is there a universal method for opening unknown files?

Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. CMDB), a simple text editor popular in the Windows system, which is Notatnik will allow us to see some of the data encoded in the file. This method allows you to view the contents of many files, but not in the same form as the program designed to serve them.

Summary of the CMDB file

These CMDB files can be viewed using one existing application software tool (s), usually ANSYS CFX developed ANSYS, Inc.... It is associated with one major file (s) type (s), but often occurs in the format ANSYS CFX Mesh Database... The CMDB file extension is listed primarily in the category Data Files.

CMDB files have been discovered on Windows platforms. They are suitable for desktops (and mobile devices). The popularity rating of these files is Low, which means that they are not very common.

If you're having trouble opening CMDB files, or simply want to know more about their associated programs and developers, see the complete information provided below.

Activity

This file type is still relevant and is actively used by developers and application software. Although the original software of this file type may be overshadowed by a newer version (eg Excel 97 versus Office 365), this file type is still actively supported by the current version of the software. This process of interacting with an old operating system or an outdated version of software is also known as “ backward compatibility».

Troubleshoot opening CMDB files

Common problems opening CMDB files

ANSYS CFX not installed

By double clicking on the CMDB file you can see a system dialog that says "This file type cannot be opened"... In this case, this is usually due to the fact that your computer does not have ANSYS CFX installed for %% os %%... Since your operating system does not know what to do with this file, you cannot open it by double clicking on it.

Advice: If you know of another program that can open your CMDB file, you can try opening that file by selecting that application from the list of available programs.

Incorrect version of ANSYS CFX installed

In some cases, you may have a newer (or older) version of the ANSYS CFX Mesh Database file, not supported by the installed version of the application... If the correct version of ANSYS CFX software (or any of the other software listed above) is not available, you may need to load a different software version or one of the other application software listed above. This problem most often occurs when working in an older version of the application software with a file created in a newer version which the old version cannot recognize.

Advice: Sometimes you can get a general idea of the version of a CMDB file by right-clicking on the file and then choosing Properties (Windows) or Get Info (Mac OSX).

Summary: In any case, most of the problems that arise when opening CMDB files are due to the fact that the correct application software is not installed on your computer.

Matroska Multimedia Container (MKV) is renowned for its versatility. Unlike other audio-video formats, MKV allows multiple files to be saved in one container, allowing functions to be layered into a file.

How to fix problems opening CMDB files

If there is a computer installed antivirus software can scan all files on the computer, as well as each file separately... You can scan any file by right-clicking on the file and selecting the appropriate option to scan the file for viruses.

For example, in this figure, file my-file.cmdb, then you need to right-click on this file, and select the option from the file menu "Scan with AVG"... Selecting this option will open AVG Antivirus, which will scan this file for viruses.

Sometimes an error can result from incorrect software installation, which may be due to a problem encountered during the installation process. It may interfere with your operating system link your CMDB file to the correct application software influencing the so-called "File extension associations".

Sometimes simple reinstalling ANSYS CFX might fix your problem by linking CMDB with ANSYS CFX correctly. In other cases, problems with file associations can result from poor software programming developer and you may need to contact the developer for further assistance.

Advice: Try updating your ANSYS CFX to the latest version to ensure the latest patches and updates are installed.

It may seem too obvious, but often the CMDB file itself may be causing the problem... If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (for example, a power outage or other reason), the file may be damaged... If possible, try to obtain a fresh copy of the CMDB file and try opening it again.

Carefully: A damaged file can cause collateral damage to previous or pre-existing malware on your PC, so it is very important that you have an updated antivirus running on your PC at all times.

If your CMDB file related to the hardware on your computer to open the file you may need update device drivers related to this equipment.

This problem usually associated with types of media files that depend on the successful opening of the hardware inside the computer, for example, sound card or video card... For example, if you are trying to open an audio file but cannot open it, you may need to update sound card drivers.

Advice: If when you try to open the CMDB file you get SYS file related error message, the problem could probably be related to damaged or outdated device drivers that need to be updated. This process can be facilitated by using driver update software such as DriverDoc.

If the steps did not solve the problem and you are still having problems opening CMDB files, it may be due to lack of available system resources... Some versions of CMDB files may require a significant amount of resources (e.g. memory / RAM, processing power) to open properly on your computer. This problem occurs quite often if you are using fairly old computer hardware and at the same time a much newer operating system.

This problem can occur when the computer has a hard time completing a task, as the operating system (and other services running in the background) can consume too many resources to open the CMDB file... Try closing all applications on your PC before opening ANSYS CFX Mesh Database. By freeing up all the available resources on your computer, you will provide a better environment for trying to open the CMDB file.

If you completed all the steps above and your CMDB file still won't open, you might need to do equipment upgrade... In most cases, even with older hardware versions, the processing power may still be more than adequate for most custom applications (unless you're doing a lot of CPU-intensive work like 3D rendering, financial / scientific modeling, or heavy multimedia work) ... Thus, it is likely that your computer does not have enough memory(more commonly referred to as "RAM", or random access memory) to perform the task of opening a file.

Try to upgrade your memory to see if it helps open your CMDB file. Nowadays, memory upgrades are quite affordable and very easy to install, even for the average computer user. As a bonus you you will probably see a nice performance boost while your computer is performing other tasks.

The most common cause of problems with opening the CMDB file is simply the lack of appropriate applications installed on your computer. In this case, it is enough to find, download and install an application that serves files in the CMDB format - such programs are available below.

Search system

Enter the file extension

Help

prompt

It should be noted that some encoded data from files that our computer does not read can sometimes be viewed in Notepad. This way we will read fragments of text or numbers - It is worth checking if this method also works in the case of CMDB files.

What if an app from the list has already been installed?

Often, an installed application should automatically link to a CMDB file. If this did not happen, the CMDB file can be successfully linked with the newly installed application manually. It is enough to right-click on the CMDB file, and then select the "Select default program" option among the available ones. Then you need to select the "View" option and find your favorite application. The introduced changes must be confirmed with the "OK" option.

Why can't i open the CMDB file?

Problems with the CMDB files can also have a different background. Sometimes, even installing software serving CMDB files on your computer will not solve the problem. The reason for the inability to open, as well as work with the CMDB file can also be:

Inconsistent CMDB File Links in Registry Entries
- corruption of the CMDB file that we open
- CMDB file infection (viruses)
- too little computer resource
- outdated drivers
- elimination of the CMDB extension from the Windows registry
- incomplete installation of the program serving the CMDB extension

The elimination of these problems should lead to free opening and working with CMDB files. In case the computer still has problems with files, you need to use the help of an expert who will establish the exact cause.

My computer is not showing file extensions, what should I do?

In standard Windows installations, a computer user does not see the CMDB file extension. This can be successfully changed in the settings. It is enough to enter the "Control Panel" and select "Appearance and Personalization". Then you need to go to "Folder Options", and open "View". In the "View" tab there is an option "Hide extensions of known file types" - you must select this option and confirm the operation by pressing the "OK" button. At this point, the extensions of all files, including CMDB, should appear sorted by file name.
