- Help for !RAMcram
- =================
-
- This application gives you the power to alter the
- size of the RAMdisc when it has some files in it (not
- normally possible). It is intended to release 'free'
- memory 'trapped' in the RAMdisc. (e.g. If you have 20kB
- of files on a 200kB RAMdisc, then approx 180kB of memory
- is not being used by the RAMdisc, but no other
- applications can use that memory)
-
- When run (by double-clicking it's icon), !RAMcram will
- bring up a window with 2 buttons ('OK' and 'CANCEL'),
- and a memory size 'strip' similar to those used in the
- desktop 'Task Display' window. At this point, you can
- cancel the operation by clicking on CANCEL, or tell
- RAMcram to go ahead by clicking on the OK button. If you
- wish to change the minimum amount of free memory in the
- RAMdisc, then drag the red bar until you acheive the
- size required (exactly as in the Task Window). For
- example, if you drag the bar to '128K', then RAMcram
- will guarantee at least 128K is free for use in the
- RAMdisc (if enough memory is free for it to do this)
- If there is not enough free memory to cram the
- RAMdisc, !RAMcram will complain. If there is enough
- memory to cram the RAMdisc, but not enough to give the
- free memory requested, the RAMdisc will remain the same
- size.
-
- Unfortunately, due to the way the Operating System
- works, RAMcram must copy every file off the RAMdisc,
- re-size the RAMdisc, and then put all the files back.
- This means that to run, RAMcram must have at least as
- much memory free as the RAMdisc has used up by files.
- RAMcram will tell you if it can't find enough free
- memory to compress the RAMdisc.
-
- RAMcram also has an upper limit of 255 files. If more
- files than this are on the RAMdisc, RAMcram will abort
- the cram.
-
- NOTE: I accept NO responsibility for any damage to
- files or loss of files arising from the use of this
- application. ONLY use RAMcram when the files on the
- RAMdisc are copies of files on floppy or hard discs,
- and can therefore be recovered from those discs if a
- problem occurs.
- Note also that directories will lose their time-stamp
- when RAMcrammed (They will be re-timestamped with the
- time and date when they were RAMcrammed), though any
- files in said directories will have correct timestamps.
