Notes about the GFS file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The GFS file type is primarily associated with 'Office Groove' by Microsoft Corporation. Office Groove is a collaboration software program that helps teams work together dynamically, even if team members work for different organizations, work remotely, or work off-line. When downloading a file new files display in the file sharing workspace with a download indicator, and are listed with the file type Groove Remote File. The file extension .GFS is appended to the file name until the download is complete (i.e., the file has a double extension; the original and the added .GFS).
