Notes about the WDT 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 WDT file type is primarily associated with 'WinDates' by Rockin' Software. The WinDates calendar software is no longer available for sale. The default calendar file created by WinDates is EVENTS.WDT.
