- NOSLACK 1.0
-
-
- NOSLACK overwrites a file's unused cluster area with zeros.
-
- DOS allocates file space on a disk in terms of fixed-length
- blocks called clusters. Since few files are exactly a multiple
- of the cluster size in length, the unused bytes at the end of the
- last cluster could possibly contain sensitive or confidential
- information left in the system memory. NOSLACK over-writes these
- unused bytes with zeros. The disk's cluster size is automatically
- detected.
-
- File attributes are preserved and READ-ONLY files are never
- touched. To wipe the slack on a READ-ONLY file, you'll have to
- change the file attribute first.
-
- The program displays a list of the files and how many bytes
- are cleared as it progresses. The total number of files affected
- is given at the end.
-
- File times and dates are preserved by default, but if you put
- a lower or upper case "T" on the command line, the file times and
- dates are set to the current time and date. In other words, this
- program can also act as a "TOUCH" utility.
-
- To interrupt the process, press the letter Q or ESC.
-
- NOSLACK entered alone without any command line arguments
- gives a small help screen.
-
- DOS wildcards in the filename can be used. If the drive and
- subdirectory aren't given, the default is the current directory.
-
- I've tested the program on several versions of DOS and on a
- commercial automatic disk compressor and I haven't found any
- problems. I can't predict how virus detection programs that watch
- for file changes would react. The only one I have available gives
- me no problems.
-
- Though I reserve the copyright, I grant the right for this
- program to be copied and used without restriction. No fee is
- required for continued use. However, if this program is used, I
- would like to request a postcard be mailed to the author. You
- don't have to give feedback or your name or address. I would just
- like an idea of how many people are using this program. This is
- only a request and not a requirement for continued use.
