What is MRR file?

The file with the extension MRR is the GIS Files file type. GIS Files consists of 255 similar files. MapInfo Map Data Format appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use MapInfo to handle this file. This is a program created by Pitney Bowes Software Inc. (MapInfo).

How to open MRR file?

The most common problem when using MapInfo Map Data Format is that a specific MRR is not associated with the program. Thus, when you open MRR, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MRR 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 MapInfo

An often overlooked issue is to make sure that MapInfo is installed on the computer. The easiest method is to use the system search engine by entering the program name MapInfo in it. 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 MRR files.

Programs to open MRR file

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

Step 2. Create association of MapInfo with MRR files

However, it may happen that the application itself does not cause the MRR file to open in the MapInfo 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 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. 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 MapInfo application as the default for handling the MRR file.

Step 3. Update MapInfo to the latest version

If, despite the association of the MapInfo program with the MapInfo Map Data Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Pitney Bowes Software Inc. (MapInfo) website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the MRR file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file MRR or the program directory. Sometimes virus-infected MRR files cannot be recovered, so make a backup in advance.
Older version of MRR file may not always be supported by the latest software version. 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. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MRR file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
When reading, a message appears that the file was encrypted or corrupted. The encrypted MRR 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 MRR file to another location.
This can happen on a file that does not support multiple access. In this case, the MRR file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the MRR file again. Some anti-virus or backup software may occupy the MRR file for a certain period of time. If nothing helps, please reset the device.
