How to open PREFAB file?

An often recurring problem with Unity Prefab Format is that PREFAB is not associated with the correct program file. Thus, when you open PREFAB, 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 PREFAB 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 Unity

The first step is to check if the computer has the Unity program installed. This can be achieved by typing Unity into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file PREFAB with Unity. Later in this article you will find a list of programs that can open PREFAB files.

Programs to open PREFAB file

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

Step 2. Create association of Unity with PREFAB files

If the application is or has been freshly installed, but the PREFAB file still does not use the Unity program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the PREFAB file with the Unity application.

Step 3. Update Unity to the latest version

If, however, after binding Unity with Unity Prefab Format there were still problems, you should update the program to the latest version. In this case, use the Unity Technologies website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the PREFAB file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our PREFAB file. Sometimes virus-infected PREFAB files cannot be recovered, so make a backup in advance.
Older version of PREFAB file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing 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 PREFAB file corruption. The easiest way to restore the file is from a backup or by contacting Unity Technologies, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted PREFAB 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. If possible, you can try to move the PREFAB file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file PREFAB to close. Some anti-virus or backup software may occupy the PREFAB file for a certain period of time. If nothing helps, please reset the device.
