I've been running into this issue for a year or two and always solve it
by just deleting files that really; I'd like to hold onto for a while
longer. Well, it's time I find out how to actually correct the issue
once and for all, so here goes:

I have my Pegasus Mail 4.41 mailbox located on a remote network storage
device (A Buffalo LinksStation 250GB Gigabit Network Storage Center)
used by several work stations, however even though there is over 75%
free space on the drive, Pmail gives me the error that the disk is near
capacity and that I need to make room or arrange for the allotment of
more space (I receive allot of large attached files). I'm using
Windows 2000 that will allow me to increase allotment of NTFS formatted
drives within the machine, but not on mapped network drives. I'm not
sure if it's coincidence or not, but the capacity Pegasus is referring
to appears to be 10% of the drive's overall capacity. The LinkStation
supposedly has no built in allotments and thus no utility to manage
them.

Previously I used a 200GB external USB drive plugged into a Linksys
Network Storage Link and it did roughly the same thing with it.

Does anyone know how I can increase the allotment that Pegasus sees on
a remote network storage drive?
