What is a SIS.DM file?
Ovi Store applications are usually installed in the background by the Ovi Store online service. However, sometimes users manually download applications and receive a file with the SIS.DM extension. These files can be converted to normal SIS files by deleting the first four lines of the file in a text editor and renaming the file extension to ".sis."
