What is RSRC file?

The file in the RSRC format belongs to the Developer Files category. It was designed by Apple. Developer Files consists of 1205 similar files. Macintosh Resource Format appears on 1 operating systems as a functional file. The file will work on Mac OS systems, unfortunately not on others. This file type can also be opened by 2 other programs. You can use Mac OS X, Resorcerer in case DeRez cannot be used.

How to open RSRC file?

The most common problem when using Macintosh Resource Format is that a specific RSRC is not associated with the program. This is manifested by the fact that RSRC 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 RSRC 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 DeRez

The first step is to check if the computer has the DeRez program installed. This can be achieved by typing DeRez into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support RSRC files.

Programs to open RSRC file

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

Step 2. Create association of DeRez with RSRC files

However, it may happen that the application itself does not cause the RSRC file to open in the DeRez application, but you can set it manually. 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. 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. The "always use the selected program ..." field will set the DeRez application as the default for handling the RSRC file.

Step 3. Update DeRez to the latest version

If, despite the association of the DeRez program with the Macintosh Resource 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 RSRC file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The RSRC file may be unusually small compared to the original file. This suggests truncating the RSRC file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file RSRC or the program directory. As a result of the scan, sometimes it is not possible to recover RSRC files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the RSRC file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged RSRC files.
The program can also signal the fact of encryption. The encrypted file RSRC except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move RSRC to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the RSRC file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
