What is SY_ file?

The file with the extension SY_ is the Compressed Files file type. It was designed by Microsoft. In addition to this file, the Compressed Files category includes 236 related files. Compressed SYS Format is supported by 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional.

How to open SY_ file?

An often recurring problem with Compressed SYS Format is that SY_ is not associated with the correct program file. This causes the file SY_ to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the SY_ 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 Microsoft Expand

In this case, you should first verify that the Microsoft Expand application is installed on the computer. To do this, enter the name Microsoft Expand into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file SY_.

Programs to open SY_ file

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

Step 2. Create association of Microsoft Expand with SY_ files

If, despite the installed application, the SY_ file does not start in the Microsoft Expand application, you must create a file association. 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. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the SY_ file with the Microsoft Expand program.

Step 3. Update Microsoft Expand to the latest version

If, despite the association of the Microsoft Expand program with the Compressed SYS Format file, the file still does not open, check the program version and possibly update it to the newest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The SY_ file may be unusually small compared to the original file. This suggests truncating the SY_ 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. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our SY_ file. However, remember that not every infected SY_ 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 SY_ 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. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged SY_ files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted SY_ 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. The problem is only writing to the file, not reading it. It is best to move SY_ to a different directory.
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. If the error persists after closing other programs, wait for a while. 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.
