Opening OMA files

Did your computer fail to open an OMA file? We explain what OMA files are and recommend software that we know can open or convert your OMA files.

What is an OMA file?

Files that contain the .oma file extension normally store Sony OpenMG music files. These files are saved in Sony's ATRAC file format. A computer user will often rip these files to a CD in order to play them on a CD player or another computer hard drive.

The OMA files that are saved to a user's hard drive may contain DRM copy protection features that prevent the music file from being played on unauthorized devices or computers. This prevents the file from being pirated or used illegally.

The OMA file format was used to distribute music through the Sony CONNECT Music Store up until March of 2008.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
