The gr_ file extension is associated with the 7-zip, a data compression tool for Microsoft Windows, developed by Igor Pavlov.

The gr_ file stores some kind of compressed archive created with 7-zip.

How to convert:

As far as we know, this .gr_ 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.
