- Uh-uh. I've seen this on the Amiga and it is brilliant. Most of the time,
- a virtual disk is empty -- it is best used to hold temporary files. Thus,
- when the disk is particulary big (4Mb+), and empty, you litteraly end up
- wasting that precious memory. Now, an intelligent RAM disk (like those
- found on the Amiga) will only "dynamically" allocate memory as it needs
- it. This can be real-RAM memory (as opposed to swappable disk memory).
- When the files are deleted from the RAM disk, the memory is released thus
- the RAM disk never wastes more system (RAM) memory then is needed to hold
- all its files, i.e. 0Kb when it's empty. I've never seen such a RAM disk
- on a PC-based system though, whether DOS-based or OS/2-based.
