Notes about the XWZ_1 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 XWZ_1 file type is primarily associated with 'Xteq X-Setup File'. (registry tweak program) (often associated with XQ_XSET_CACHE)
