How to open FSSX file?

An often recurring problem with FolderSizes Data Format is that FSSX is not associated with the correct program file. This causes the file FSSX to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

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

In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file FSSX.

Programs to open FSSX file

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

Step 2. Create association of FolderSizes with FSSX files

However, it may happen that the application itself does not cause the FSSX file to open in the FolderSizes application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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 FSSX file with the FolderSizes program.

Step 3. Update FolderSizes to the latest version

If, however, after binding FolderSizes with FolderSizes Data 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 Key Metric Software page and install.

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

The affected file may be 0 KB or smaller than expected. This suggests truncating the FSSX 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 FSSX or the program directory. However, remember that not every infected FSSX file can be recovered, so it is important to take care of regular backups.
Older version of FSSX 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. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged FSSX files. 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 FSSX 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 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. It is best to move FSSX to a different directory.
This problem only occurs with 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 it is necessary to wait a while before referencing the FSSX file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
