What is AST file?

The file in the AST format belongs to the Settings Files category. The author of this format is Adobe Systems. In addition to this file, the Settings Files category includes 1305 related files. Adobe Color Separations Table is most often found on 2 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Mac OS, Windows. The Adobe Photoshop application is recommended to open the file. It was released by Adobe Systems Incorporated. This file type can also be opened by 3 other programs. You can use Adobe Acrobat in case Adobe Photoshop cannot be used.

How to open AST file?

The most common problem when using Adobe Color Separations Table is that a specific AST is not associated with the program. Thus, when you open AST, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the AST 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

The first step is to check if the computer has the Adobe Photoshop program installed. This can be achieved by typing Adobe Photoshop into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open AST files.

Step 2. Create association of Adobe Photoshop with AST files

If the application is or has been freshly installed, but the AST file still does not use the Adobe Photoshop 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the AST file with the Adobe Photoshop program.

Step 3. Update Adobe Photoshop to the latest version

If, however, after binding Adobe Photoshop with Adobe Color Separations Table there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the AST file contents when downloading or copying. 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. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file AST or the program directory. As a result of the scan, sometimes it is not possible to recover AST files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the AST files changes over time. 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair AST file corruption. You can restore the file from a backup or use Adobe Systems help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted AST files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the AST file to another location will fix the problem.
This problem usually affects more complex files. In this case, the AST file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the AST file again. Some anti-virus or backup software may occupy the AST file for a certain period of time. If the problem persists, restart the machine.
