How to operate timely backup system?
Pull-down Menu: Tool>Option>Open and Save In File Safety Precautions choose Automatic Save and set the time interval such as 5 minutes. When choosing the file style if you choose Single DWG File Save system will automatically save file to be .SV$. In fact .SV$ files are standard DWG files. .SV$ files can be opened after changing the suffix to be DWG. But the save time is slow and not suit for the auto save with short time interval. If you choose Quick Multiple Files Save, system will automatically save file to be .dwh, the speed is very fast and suit for timely backup requirement. Suggest users not to choose Save a Preview Image because it affects the save speed.
