-
- I use PCKWIK's disk cache, screen accelerator, and keyboard
- accelerator together on my 1982 PC. They're packaged together and sell
- for a very reasonable price.
-
- Also, I take care in organizing my file sytem. The first-level
- directories on my disk contain only subdirectories or batch files.
- For example:
-
- |-----wordproc------- wordperf
- |
- |- cgrammar
-
- The batch file to run Correct Grammar might look like this:
-
- @Echo off
- Rem - Executes Correct Grammar
- Cls
- Echo ..Loading Correct Grammar Program
- C:
- Cd \WordProc\CGrammar
- CG.EXE
- Cd \Socrates
- Cls
-
- (Socrates is the machine's home directory.) The advantage of the
- above is that the PATH variable has few directories, and few files in
- each to search. (Place \DOS last.)
-
- Also, I defragment my disk every other day. DOG (a shareware program)
- is most flexible.
-
- Usually I just place the directories and batch files first on the disk,
- for this is most important and fast to do. But regularly organize the
- disk as follows:--
-
- Right after the system files, I place the directories, then the batch
- files; then I place the remaining files, grouped by directory. The
- directory \WordProc\CGrammar I may place first, if it needs to access
- files from disk as it runs. Within each directory I sort the files by
- filename, for (somedays) I convince myself that this best places files
- that will be needed for a single task adjacent to one another on the
- disk. This helps cache them together, if the cache reads ahead.
-
- Finally, I make sure temporary files and swap files are not fragmented
- when they're written. This means placing them away out on the disk by
- themselves, if their upper size isn't predictable; or placing them
- before the batch files in a region of fixed size, if their size is
- pre-determined. (I crash the program that creates the swap file, move
- it where I want it when defragmenting, then--depending on the
- program--use attributes or other methods to keep the swap space
- intact.)
-
- Many programs for XT's will take advantage of expanded memory, for
- swapping to disk is painfully slow. I installed an Intel AboveBoard
- and placed my disk cache there. It shrinks as applications need the
- space.
