When Microsoft Undelete is using the Delete Sentry level ofprotection, files that are deleted are stored in a hidden SENTRYdirectory in the root of the drive. These files are automaticallypurged from the drive under the following conditions:

  • MS-DOS requires the disk space. For example, if the drive is full and you are saving updates to a data file, enough files are removed from the hidden SENTRY directory so that you can save your data.
  • Files in the hidden SENTRY directory are taking up too much space on the drive. By default, Delete Sentry allows files to take a maximum of 20% of total the drive space.
  • Files in the hidden SENTRY directory are too old. By default, files are saved for seven days. Purging of old files occurs when Microsoft Undelete is loaded (typically from the AUTOEXEC.BAT file).
In each case, files are purged in chronological order (oldest first).
You can adjust the maximum amount of disk space allowed for deletedfiles or the number of days to save deleted files.

To change options using Microsoft Undelete for Windows:

  1. From the Options menu, choose Configure Delete Protection.
  2. Select Delete Sentry and choose the OK button.
  3. In the Configure Delete Sentry dialog box, set the Maximum Number Of Days To Save Deleted Files and Maximum % Of Disk Space For Deleted Files.
  4. Choose the OK button.


    Use a text editor to change the [Configuration] section of theUNDELETE.INI file:

    1. Set percentage= to the maximum percentage of disk space for deleted files.
    2. Set days= to the maximum number of days to save deleted files. For example:
         [configuration]   days=5   percentage=50
The next time you load Undelete, the new settings are active.
