As we know, 'Undelete' was very old command that ever created back to the MS-DOS kingdom. What does it become in the Windows 10?

If anyone could ever recall our MS-DOS history and its continues involving, from the starting of windows 86-based operating system to current state, even its name had made dramatic changes, for instance, command prompt became a much more acceptive by public opinion.

In windows 10, many features have been re-written and many command-line/syntaxes have been wiped out of history, not even to mention the long-gone “undelete”.

History of undelete:

It was originated from ms-dos operating platform, undeleted was widely used in order to take a step back after deletion was executed through ms-dos, its existence represented itself in the following form as its index shown:


UNDELETE [d:][path][filename] [/DT|/DS|/DOS]
UNDELETE [/list|/all|/purge[d:]|/status|/load|/U|/S[d:]|/Td:[-entries]]

Purpose: Restores files deleted with the DELETE command.


Used to recover files that have been previously erased. The UNDELETE command can only recover deleted files if no new files or changes have been made on the disk since the deletion. Therefore, if you accidentally delete a file that you want to keep, stop what you are doing immediately and use the UNDELETE command to retrieve the file.


/all - This one can help recover all files that you specify.

/list - To list the files (but files are not recovered).

/DOS Restricts recovery to those files that meet the file specifications (filespec) in the disk directory table.

/DT - Restricts recovery to those files found in the Delete Tracking File.

/DS - Restricts recovery to those files found in the SENTRY directory.

/load - Loads the Undelete memory-resident program into memory using information defined in the UNDELETE.INI file.

/unload - Unloads the memory-resident portion of the Undelete program from memory, turning off the capability to restore deleted files.

/purged[d] - Deletes the contents of the SENTRY directory.

/status - Displays the type of delete protection in effect for each drive.        

/S[d] - Enables the Delete Sentry level of protection and loads the memory-resident portion of the UNDELETE program.


For computer starters, do you still remember the retro era of computing? I know I do. When first time get a close touch of windows systems, command prompt is the first thing to learn during the “computer stone age”. As it develops, most of the old commands were slowly ruled out and unfortunately, “undelete” became one of it. Talking about went missing? Those ancient “command line” is the real dinosaur.
