How to open CALS file?
An often recurring problem with CALS Raster Graphic Format is that CALS is not associated with the correct program file. This is manifested by the fact that CALS files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the CALS 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 Adobe Photoshop
An often overlooked issue is to make sure that Adobe Photoshop is installed on the computer. To do this, enter the name Adobe Photoshop into the system search engine.

Programs to open CALS file
Remember to download programs supporting CALS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Adobe Photoshop with CALS files
If, despite the installed application, the CALS file does not start in the Adobe Photoshop application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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 set the program to handle this type. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CALS file with the Adobe Photoshop application.
Step 3. Update Adobe Photoshop to the latest version
If, however, after binding Adobe Photoshop with CALS Raster Graphic Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Adobe Systems Incorporated page and install.
Step 4. Check for the following problems with the CALS file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
Very often, the file may be size 0 or incomplete. Usually this applies to CALS files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the CALS file that we want to open. However, remember that not every infected CALS file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the CALS files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged CALS files. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted CALS 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the CALS file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file CALS to close. However, some background programs may block the CALS file while scanning. If nothing helps, please reset the device.
