Notes about the GAS 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 GAS file type is primarily associated with 'Grab-a-Site' by BlueSquirrel. Grab-a-Site 5.0 is a file-based offline browser that can download an entire Web site while retaining the original filenames and directory structure.
