How to open CHECK file?

An often recurring problem with CASTEP Check Binary Data Format is that CHECK is not associated with the correct program file. Thus, when you open CHECK, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the CHECK file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install CASTEP

Programs to open CHECK file

Remember to download programs supporting CHECK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of CASTEP with CHECK files

If the application is or has been freshly installed, but the CHECK file still does not use the CASTEP program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the CHECK file with the CASTEP program.

Step 3. Update CASTEP to the latest version

If, despite the association of the CASTEP program with the CASTEP Check Binary Data Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Castep team website and install the latest version.

Step 4. Check for the following problems with the CHECK file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to CHECK files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file CHECK or the program directory. As a result of the scan, sometimes it is not possible to recover CHECK files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CHECK file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair CHECK file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
The program indicates that the file is encrypted or corrupted. The encrypted CHECK files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the CHECK file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file CHECK to close. However, some background programs may block the CHECK file while scanning. If the problem persists, restart the machine.
