- ABOUT THIS PROGRAM
- ---------------------------------------------------------------------------
- Name : ClearDisc
- Version : 1.01 (25 Jun 1996)
- Purpose : Remove deleted files from disc
- Author : © Andrew Berry, 1996
- Licence : Freeware. Please see conditions at the end of this file.
-
- ClearDisc supports Interactive Help.
-
-
- BACKGROUND
- ---------------------------------------------------------------------------
- When a file is deleted from disc the reference to the file is removed, but
- the actual file data remains on the disc, even though is is not accessible
- in the normal way from a filer window. It is only erased when a new file is
- saved on top of it. If you pass a disc on to someone with a disc sector
- editor or a copy of Zap (the text/memory editor) then they can read all the
- files which you deleted. One answer is to format the disc before passing it
- on, but there may be some files which you want to leave on the disc, and
- this would mean moving them to another disc, formatting, and then
- transferring the wanted files back again. It would be helpful if a program
- could erase the data of any files which had been deleted, while leaving
- undeleted files alone. This was my reason for writing ClearDisc.
-
-
- PURPOSE
- ---------------------------------------------------------------------------
- ClearDisc will erase all data which has been left behind by deleted files,
- meaning that a file which has been deleted becomes unreadable. Please note
- that it is NOT possible to undelete files once this program has been used.
-
-
- USING
- ---------------------------------------------------------------------------
- To clear the files from a disc in drive 0 insert the disc into the drive,
- ensuring that it is write enabled. Click on the ClearDisc icon on the icon
- bar and a confirmation message will appear. Click on OK and all deleted
- files will be erased.
-
- Due to the method used to remove the data, D- and L-Format discs should be
- compacted before using this program in order for all deleted files to be
- removed effectively. My DiscComp program will do this for you - see below
- if you would like a copy.
-
-
- OPTIONS
- ---------------------------------------------------------------------------
- The ‘Options’ submenu (from the icon bar menu) contains three options.
- These are as follows:
-
- Drive : The drive submenu enables you to switch between drives 0, 1,
- 2 and 3. In a future version drives will be greyed out if
- they are unavailable.
-
- Confirm : If this is selected then confirmation will be requested
- before processing each disc. I’ve included this as an option
- because clearing a disc can do no harm to the undeleted data
- on it and you will probably want to turn it off.
-
- Hourglass : If this option is selected then a percentage hourglass will
- appear while the disc is being processed so you know roughly
- how long the operation will take.
-
- The final item in the ‘Options’ submenu is ‘Save’. This will save the
- selected options as the defaults, and they will be used each time ClearDisc
- is loaded.
-
