Troubleshooting Problems Opening OSF Files

Issues Opening OSF Files

Descent 3 Disappeared

When trying to open your OSF file, you get the error "Can't Open OSF File Type". When this happens, it is commonly due to Descent 3 missing in - . Your operating system cannot associate your OSF with Descent 3, so double-clicking the file won't work.

Tip: If you don't have Descent 3 installed, and you know of another program to open your OSF file, you can try opening it by selecting from the programs listed under "Show Apps".

Outdated Descent 3

Tip: Investigate your OSF file by right-clicking and selecting "Properties" to find clues on what version you need.
