.STEAMSTART File

The steamstart file extension is associated with Steam Client by Valve.

Whenever a game installed in Steam is launched a temporary steamstart file is created for some DRM or internal purposes.

Files with the steamstart extension can be generally found as temporary data files from the Steam Client developed by Valve.

How to open:

These files are not meant to be opened directly, they are generated for temporary purposes.

How to convert:

As far as we know, this .steamstart file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
