hi Michele,

I too have 64MB and 5.1 MB HDD on my Win98, but still use Drive Space (very
good place for all the docs dloaded from Internet, IE and Navigator caches,
Outlook mail). The other benefits are that my main partition is not
fragmeted so much by this small files and don't lose space 'cause of big
cluster sizes.
Also on all my NT boxes I use compressed directories for all log's
generated, proxy server caches, and can tell you it is very cool. Example
when I removed (copied it on CD) all logs generated by MSProxy and IIS
servers around 500 MB, I freed only ~100 MB disk space i.e. ~1/5 compresion
ratio. What about /var/log dir :") and muLinux, in 1MB RAM you can save ~4
MB logs.
OK. I made the following test, zipped HDD-muLinux all 3 disks.
Unziped - 12,3 MB
Ziped - 5,18 MB :")
And we all talk to use as possible as small/inexpensive hardware for all
small Linuxes. What about Flash'es. just a tought.

Ciao, iVAN :")
