How to open R03 file?

The main problem with WinRAR Split Archive Part 3 is that the R03 file is incorrectly associated with programs. This is manifested by the fact that R03 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 R03 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 RARLAB RAR

In this case, you should first verify that the RARLAB RAR application is installed on the computer. To do this, enter the name RARLAB RAR into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open R03 files.

Step 2. Create association of RARLAB RAR with R03 files

If, despite the installed application, the R03 file does not start in the RARLAB RAR application, you must create a file 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. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the R03 file with the RARLAB RAR application.

Step 3. Update RARLAB RAR to the latest version

The fault may also lie with the RARLAB RAR program, it is possible that WinRAR Split Archive Part 3 requires a newer version of the program.

Step 4. Check for the following problems with the R03 file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to R03 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
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. The scan should cover the entire computer, not only the R03 file that we want to open. As a result of the scan, sometimes it is not possible to recover R03 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 R03 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. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular R03 file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted R03 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. The problem is only writing to the file, not reading it. If possible, you can try to move the R03 file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file R03 to close. 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.
