- QU (Quick UnErase)
-
-
- Description: Recovers erased files in a selected directory if the file's
- primary cluster has not been reallocated to another file. You
- can direct QU either to provide a unique first character for a
- file or to prompt you for a character. If a file is larger
- than one cluster, QU makes a ``best guess'' when reallocating
- clusters to the erased file.
-
- Syntax: Version 3.1: QU [(drive:)][(path)] [/A]
-
- Version 4.0, 4.5: QU [(drive:)][(path)][(filespec)] [/A]
-
- Parameters:
-
- (drive:) The single-letter specifier (A:, B:, C:, etc.) for the drive
- you want to use. Follow the letter with a colon. The current
- drive is the default.
-
- (path) The full name (C:\WP\LETTERS) of the directory you want to
- search for deleted files. The current directory for the
- designated drive is the default.
-
-
- (filespec) The name of the file you want to unerase. For example, enter
- QU .BAT if you want to unerase all files with a BAT extension.
- If you supply the first character for the filename pattern, QU
- unerases all files whose names match the pattern and prompts
- you for acknowledgment or for a first character only if erased
- filenames were identical except for the first character.
-
- /A Requests QU to generate erased filenames. In versions 4.0 and
- later, if you do not use this switch and you do not specify
- the first character of the file in (filespec), QU prompts you
- to confirm each file to be unerased and asks you to provide
- the first character for each candidate file. After you run QU
- with this switch, use the MS-DOS Rename command to correct the
- names of the restored files.
-
- Notes:
-
- Because QU makes a ``best guess'' about the clusters that originally belonged
- to a multiple-cluster file, the utility might not always unerase the file
- correctly. If a file does not contain the data you expected after you restore
- it with QU, delete the file again and use the unerase function of NU to
- search for the clusters that should be assigned to the file.
