Whats the meaning of the speedy multi-files in auto-save?
Backup system simultaneously records users’ entire drawing process and no necessary to worry about any lost of your work by the unexpected error. Its automatic backup system adopts a new vector image format (with the suffix .dwh) originally created by GreatStar Software, Comparing with the standard .dwg file, automatic and timely backup system greatly increases automatic backup speed, for example when the drawing size is no more than 10M, time for backup is about one second. This prompt backup system achieves real time (e.g. automatically backup every 5 minutes). In case of accidents, such as power failure or abnormal exit, it will restore to the last-edited drawing, reducing losses to minimum. In addition, users can set how many copies and how long it will be kept. If you save wrong drawing after improper operation or delete the drawing by mistake, you can restore the file by inputting file name and the save time.
