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.
Example: To automatically restore all erased files in the GAMES
directory in drive B.
Enter: QU b:\games /A
