How to open RSU file?

The most common problem when using Reflection For IBM Updated Settings is that a specific RSU is not associated with the program. This is manifested by the fact that RSU files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the RSU 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 Reflection

In this case, you should first verify that the Reflection application is installed on the computer. The easiest method is to use the system search engine by entering the program name Reflection in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support RSU files.

Programs to open RSU file

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

Step 2. Create association of Reflection with RSU files

If the application is or has been freshly installed, but the RSU file still does not use the Reflection program, it means no 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. 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 RSU file with the Reflection application.

Step 3. Update Reflection to the latest version

The fault may also lie with the Reflection program, it is possible that Reflection For IBM Updated Settings requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Attachmate Corporation page and install.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. Usually this applies to RSU 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 operating system may be infected with a computer virus. 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 RSU file that we want to open. Sometimes virus-infected RSU files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the RSU 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.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular RSU file corruption. You can restore the file from a backup or use Attachmate Corporation help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file RSU 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. Copying the RSU file to another location will fix the problem.
This problem usually affects more complex files. In this case, the RSU file is blocked by the first application to open it. 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 RSU file while scanning. If the problem persists, restart the machine.
