|
|
* Copyright (c) 1987-1990, Microsoft Corporation. All rights reserved.
|
||
|
|
*
|
||
|
|
* Purpose:
|
||
|
|
* The three tools EXP, RM and UNDEL are used to delete files so
|
||
|
|
* that they can be undeleted. This is done my renaming the file into
|
||
|
|
* a hidden directory called DELETED.
|
||
|
|
*
|
||
|
|
* Notes:
|
||
|
|
* All deleted files are kept in the directory .\deleted with a unique name.
|
||
|
|
* The names are then kept in .\deleted\index.
|
||
|
|
* deleted name (RM_RECLEN bytes).
|
||
|
|
* The rm command will rename to the appropriate directory and make an entry.
|
||
|
|
* the undelete command will rename back if there is a single item otherwise
|
||
|
|
* it will give a list of alternatives. The exp command will free all deleted
|
||
|
|
* objects.
|
||
|
|
*
|
||
