ΓòÉΓòÉΓòÉ 1. Introduction ΓòÉΓòÉΓòÉ
PM UNDELETE will allow you to undelete one or more files by selecting them from
a PM window. By default all files available for UNDELETE will be displayed in
the window. However you may restrict this list to a single directory. You may
also use the Filename Mask to create very percise lists of the files you desire.
All entry fields in PM UNDELETE have defaults. However you may override any of
these defaults to have a custom display of only certian files.
Once you are satisfied with the choices you have made select Refresh to display
the files available for UNDELETE processing.
Then select your files from the list provided and initate the UNDELETE to watch
your files come back!
ΓòÉΓòÉΓòÉ 2. Undelete Command ΓòÉΓòÉΓòÉ
You may invoke the undelete process 3 ways:
o By selecting files in the list box and pressing the accelerator key Ctrl+U.
o By selecting files in the list box and choosing Undelte from the Files
menu on the Action bar.
o By selecting files in the list box and then double clicking the mouse on
one of the selected files. (See Extended Selections for more infomation on
how mouse selections are processed).
ΓòÉΓòÉΓòÉ 3. Extended Selection ΓòÉΓòÉΓòÉ
With Extended Selection, you may swipe items to select a large group from the
list box.
If you click on a list item while holding down the Ctrl key, the selection for
that item is toggled.
Clicking on an unselected item selects that item and deselects all others.
Once you have completed selections you may invoke the UNDELETE process.
ΓòÉΓòÉΓòÉ 4. Filename Mask ΓòÉΓòÉΓòÉ
Use the Filename Mask field to restrict your search. In this field you should
specify any subdirectory or meta characters. For example:
\os2\*.ini
This will display any deleted .ini files on the \os2 subdirectory tree. The
Subdirectories Help gives examples showing how far down the \os2 tree PM
UNDELETE will go to build your list.
As a further example of the power of meta characters assume that these files
have been deleted and are eligible for the UNDELETE list:
FRED01_RPT.DOC
FRED01_OUT.DOZ
BILL01_RPT.DOZ
BILL02_OUT.DO
JIM01_R.DO
If the mask specified is
*01_R*.DO?
The results will be
FRED01_RPT.DOC
BILL01_RPT.DOZ
JIM01_R.DO
Note: Conventionally '?' should match 1 character exactly; while *' matches 0
or more. However in OS/2 2.1 '?' actually seems to match 0 or 1 characters.
This could cause unexpected problems in other operations but, at worst, will
just give you a few more files than you had thought it would in PM UNDELETE.
This is probably not a particularly important distinction since I don't know
anybody who actually uses '?' anyway. It's just one of the things one learns
while testing out software.
ΓòÉΓòÉΓòÉ 5. Drive Selection ΓòÉΓòÉΓòÉ
This spin button will display all the drives which are available for UNDELETE
processing. PM UNDELETE will only process one logical drive at a time. Choose
which drive to process here.
ΓòÉΓòÉΓòÉ 6. System Configuration ΓòÉΓòÉΓòÉ
In order to use PM UNDELETE, you must have the DELDIR environment variable set
in your CONFIG.SYS file. The most common format for this command would be
something like:
SET DELDIR=C:\DELETE,512;D:\DELETE,512;
This line will set up your system so the UNDELETE command can be used.
Specifically it will cause files that you delete, on drive C: or D:, to be
moved to the \DELETE directory and marked as System and Hidden. Files will be
moved to this directory until the maximum amount of disk space you have
specified is allocated to deleted files. In this example, up to 512K bytes of
files will be stored in the directory at a time.
Once you delete more files, the oldest files will be scratched. That is, they
will be truly deleted from your system in a FIFO (First In First Out) manner.
It is possible to recover them even after that has happened, however then you
get into the same problems as programs like PHOENIX: mainly clusters already in
use by another file.
ΓòÉΓòÉΓòÉ 7. Subdirectories ΓòÉΓòÉΓòÉ
Select Include to see all deleted files from the point you specify downward.
For example if you were to specify \OS2\* in the filename mask, you would see
any deleted files in:
\OS2
\OS2\DLL
\OS2\DLL\DISPLAY
\OS2\SYSTEM
\OS2\SYSTEM\TRACE
...etc
However if you select Exclude and supplied the same filename mask, \OS2\*, you
would only see deleted files that had been in the \OS2 directory.
ΓòÉΓòÉΓòÉ 8. Refresh ΓòÉΓòÉΓòÉ
Choose Refresh to redisplay the list of files available to UNDELETE.
You must choose this Pushbutton when you first bring up the program. You will
probably want to set the Drive and Filename Mask values first.
You should also choose this item if you change either of these fields or if
files are deleted by another application while PM UNDELETE is running.
ΓòÉΓòÉΓòÉ 9. Cancel ΓòÉΓòÉΓòÉ
Use the Cancel button to close the application and exit.
You may also press F3 or choose Exit from the File menu.
ΓòÉΓòÉΓòÉ 10. Select All / Deselect All ΓòÉΓòÉΓòÉ
Choose Select All to highlight all files in the list. This will select them
ALL for processing. If you then chose UNDELETE ALL files would be recovered.
Choose Deselect All to unhighlight and unselect them ALL. If you then chose
UNDELETE NO files would be
