Greetings, Recently i heard of a device driver called `Squish' which compressed/decompressed data to/from the disk drives so that one obtained twice the usable space. Does anyone have experience with this or similiar creatures? I am assuming that this would also apply to the ram disk, effectively doubling it also. Any ideas or feedback would be much appreciated.

Any compression algorithm is going to do well on some data and poorly on others. In the case, say, of a compressed file (such as a ZIPfile or an .exe that has been LZEXE'd), the device driver may not be able to compress the data at all. In fact, it may _expand_ the data in the attempt. There will also be a time penalty paid for a software approach, as well as a memory penalty. Most of the powerful compression techniques need a hefty chunk of memory in which to work. -- Roy M.
