Setting Automatic Save and Backup Options¶

To protect your drawing files, use automatic save and backup options.

When a drawing closes normally, the autosave files are deleted.

To set automatic save and backup options:

Click Tools > Options (or type Options).
In the Options dialog box, click System Options .
Expand Auto-save & Backup.
Expand Automatic save file location to set the folder for automatically generated saved files (files of type .ds$).

Click Browse to browse for the folder.
Expand Auto-save/backups to set:
- Enable auto-save: Automatically saves the drawing to autosave files (files of type .ds$). You can specify the interval for auto-save in minutes.
- File extension for automatic save file: Specifies the file extension for autosave files (default is .ds$).
- Save backup at each save: Controls whether backup copies (files of type .bak) are created each time you save a drawing.
- Use original format: Specifies whether backup files are saved in its original drawing file version or in the current file version.
- Incremental save: Specifies approximately the amount of space allocated in drawing files (in percent) for incremental saves, which affects the number of incremental save operations that can be performed before a full save is required:
  - If the value is equal to 0, a full save is performed each time.
  - If the actual percentage of wasted space is less than or equal to the specified value, an incremental file save is performed.
  - If the actual percentage of wasted space is greater than the specified value, a full save is performed.
  Valid values range between 0 and 100 percent. The default value is 50 percent.
Click OK.
