What is a SISX.DM file?
Typically, the Nokia Ovi Store installs applications in the background without the user seeing the installer file. However, sometimes users manually download applications as SISX.DM files (or .SIS.DM files) using a Web browser. These files can be converted to normal SISX files by deleting the first four lines of text in the file and renaming the extension to ".sisx."
