I finally took Gareee's advice and got a big HDD so I wouldn't
have to spend so much time on disk housekeeping. 

Just to be sure, are there any known problems or big advantages
in moving Poser to a disk that isn't the main Windows disk?

(I'm 98% sure this is OK, but I vaguely recall hearing about
some problems, which may have been irrelevant.)

Also, for other big apps that need to be in Program Files, can
Windows deal with having a C:Program Files and also F:Program Files?
Or does that need to be unique?

Through my experience there shouldn't be any major problems.  There may be issues if it starts to look for something engrained on the primary drive designation but that may need to be addressed through the application properties.  Typically, I keep all major programs on the C: but I see no reason or problems relocating Poser onto a secondary drive.

OK, thanks.  Here goes!

.......Yup, worked fine.  No problems.

Not sure about another entirely separate drive, but my main drive is divided into partitions,
and I keep all my graphics files on the D: partition, Vue, Poser, Paint Shop Pro, Daz Studio,
Wings 3d, Shade, etc..  Also I don't lump them all into a Programs File folder, each is
in the root folder, ie D:/Smith Micro for Poser.  I have hardly anything in the C: partition,
just Windows, so that I can periodically reformat the C: partition and then just
reinstall Windows without having to restore everything else to that partition.
(Windows get so much junk in it that after a while it gets too cranky and slow,
a reformat and reinstall makes it run better for a while.)
Been doing this for years and haven't had any problems with Poser.

a Partition is treated as a seperate drive in this instance. you can install poser where ever you want.. I've had it on C, D, E, F, Single Drive partitions and multidrive configs.

I think, tho I've not tried it, you could in theory run poser over a network by mapping the share to a drive letter - in theory it would work, but I have no idea what the results would be.

Actually PoserPro has been set up to link to runtime folders on a network.  I do have multiple computers at home, maybe I'll try it someday.
