How to open REU file?

The main problem with Commodore C64 REU Image Format is that the REU file is incorrectly associated with programs. This is manifested by the fact that REU 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 REU 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 VICE

The first step is to check if the computer has the VICE program installed. To do this, enter the name VICE into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file REU with VICE. Below you will find a list of applications that support REU files.

Programs to open REU file

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

Step 2. Create association of VICE with REU files

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

Step 3. Update VICE to the latest version

If, however, after binding VICE with Commodore C64 REU Image Format there were still problems, you should update the program to the latest version. In this case, use the VICE website or update the program from the application.

Step 4. Check for the following problems with the REU 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. Usually this applies to REU files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. 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 REU file. As a result of the scan, sometimes it is not possible to recover REU 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 REU file. 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.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair REU file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted REU files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the REU file to another location will fix the problem.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the REU file while scanning. If the problem persists, restart the machine.
