These are audio files, like AAC-LC and AMR-WB. This format is produced by 3rd Generation Partnership Project. They used for storing audio data. The 3GA audio files are supported by nokia and Samsung. These file are compatible with lots of audio players. The .3GA file extension is also associated with 3GPP multimedia files. The .3GA file can only read audio from the 3GPP. Both these formats are used for recording over the internet.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .3GA file, there may be several reasons that cause problems with opening and operation of the data format:
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 .3GA file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .3GA file, so download the update and check again.
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:
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.
