UNDELETE

Restores files that were previously deleted by using the <DEL> command. UNDELETE offers three levels of protecting files against accidental deletion-- Delete Sentry, Delete Tracker, and standard. For information about each level of protection, see Notes. For information about the Windows version of UNDELETE, see the chapter "Managing Your System" in the MS-DOS User's Guide, or see Windows Undelete Help. Syntax UNDELETE [[drive:][path]filename] [/DT|/DS|/DOS] UNDELETE [/LIST|/ALL|/PURGE[drive]|/STATUS|/LOAD|/UNLOAD |/S[drive]|/Tdrive[-entries]] Parameter [drive:][path]filename Specifies the location and name of the file or set of files you want to recover. By default, UNDELETE restores all deleted files in the current directory. Switches /LIST Lists the deleted files that are available to be recovered, but does not recover any files. The [drive:][path]filename parameter and the /DT, /DS, and /DOS switches control the listing produced by this switch. /ALL Recovers deleted files without prompting for confirmation on each file. UNDELETE uses the Delete Sentry method, if it is present. If Delete Sentry is not, UNDELETE uses Delete Tracker, if present. Otherwise, UNDELETE recovers files from the DOS directory, supplying a number sign (#) for the missing first character in the filename. If a duplicate filename already exists, this switch next tries each of the following characters, in the order listed, until the result is a unique filename: #%&0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ. /DOS Recovers only those files that are internally listed as deleted by MS-DOS, prompting for confirmation on each file. If a deletion-tracking file exists, this switch causes UNDELETE to ignore it. /DT Recovers only those files listed in the deletion-tracking file, prompting for confirmation on each file. /DS Recovers only those files listed in the SENTRY directory, prompting for confirmation on each file. /LOAD Loads the Undelete memory-resident program into memory using information defined in the UNDELETE.INI file. If the UNDELETE.INI file does not exist, UNDELETE uses default values. /UNLOAD Unloads the memory-resident portion of the Undelete program from memory, turning off the capability to restore deleted files. /PURGE[drive] Deletes the contents of the SENTRY directory. If no drive is specified, UNDELETE searches the current drive for the directory. /STATUS Displays the type of delete protection in effect for each drive. /S[drive] Enables the Delete Sentry level of protection and loads the memory-resident portion of the UNDELETE program. The program records information used to recover deleted files on the specified drive. If you do not specify a drive, using this switch enables the Delete Sentry level of protection on the current drive. Specifying the /S switch loads the memory-resident program into memory using the information defined in the UNDELETE.INI file. /Tdrive[-entries] Enables the Delete Tracker level of protection and loads the memory-resident portion of the UNDELETE program. The program records information used to recover deleted files. The required drive parameter specifies the drive containing the disk for which you want UNDELETE to save information about deleted files. The optional entries parameter, which must be a value in the range 1 through 999, specifies the maximum number of entries in the deletion-tracking file (PCTRACKR.DEL). The default value for entries depends upon the type of disk being tracked. The following list shows each disk size, its default number of entries, and its corresponding file size: Disk Entries File size size
360K 25 5K 720K 50 9K 1.2 MB 75 14K 1.44 MB 75 14K 20 MB 101 18K 32 MB 202 36K >32 MB 303 55K CAUTION: Do not use deletion tracking for any drive that has been redirected by using the JOIN or SUBST command. If you intend to use the ASSIGN command, you must do so before using UNDELETE to install deletion tracking.
