What is GMAP file?

The file with the extension GMAP is the GIS Files file type. The author of this format is Garmin. GIS Files consists of 255 similar files. Garmin Map Format appears on 2 operating systems as a functional file. The file will work on Mac OS, Windows systems, unfortunately not on others. Alternatively, you can use 1 other programs. You can use BaseCamp in case Garmin BaseCamp cannot be used.

How to open GMAP file?

The main problem with Garmin Map Format is that the GMAP file is incorrectly associated with programs. This is manifested by the fact that GMAP 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 GMAP 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 Garmin BaseCamp

The first step is to check if the computer has the Garmin BaseCamp program installed. The easiest method is to use the system search engine by entering the program name Garmin BaseCamp 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 GMAP files.

Programs to open GMAP file

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

Step 2. Create association of Garmin BaseCamp with GMAP files

If, despite the installed application, the GMAP file does not start in the Garmin BaseCamp 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 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. Checking the "Always use the selected program ..." box will permanently associate the GMAP file with the Garmin BaseCamp program.

Step 3. Update Garmin BaseCamp to the latest version

The fault may also lie with the Garmin BaseCamp program, it is possible that Garmin Map Format requires a newer version of the program.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the GMAP file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the GMAP file that we want to open. Sometimes virus-infected GMAP 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 GMAP files changes over time. 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 GMAP file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted GMAP 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 of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the GMAP file to another location.
This problem only occurs with more complex files. In this case, the GMAP file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the GMAP file while scanning. If the problem persists, restart the machine.
