[comp.binaries.ibm.pc.d] soft-overflow ramdisk for MSDOS?

dhw@itivax.iti.org (David H. West) (11/25/89)

Has anyone seen an MSDOS ramdisk which, when full, overflows
uncomplainingly onto real disk?  That way, when ram is scarce, one
could have the speed advantages of ramdisk much of the time by
allocating to ramdisk what little ram one can spare, without risking
the fatal errors otherwise resulting from ramdisk overflow.  I have
in mind the use of ramdisk for a /tmp directory, for which the
frequency distribution of space-required vs. occasions-of-use is very 
skewed.

This isn't trivial to write, because in some circumstances every
file on the ramdisk might need to be continued on real disk, and so
might the root directory (maybe avoid the latter problem by keeping the 
ramdisk cd'ed to a subdirectory?).

Freeware or shareware preferred; I have ftp.
