Remember!

The .AMR file extension can correspond to several not related file formats. If there is more than one file format with the .AMR extension, you will probably find most of them at this website. Remember that you need to download a program to support a particular file type. So first look through the entire contents of the website to select a program to support just the file you have.

Other possible reasons why your .AMR file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .AMR file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .AMR file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .AMR file, so download the update and check again.

2. Incorrect .AMR file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .AMR file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
