OK, the question is very n00bish, but I rather make an idiot out of myself
that foul up the installation.
Am I correct that I can ad lib rename everything in runtime/libraries/$category
and downloads/runtime/libraries/$category as long as I keep my hands off
runtime/texture and runtime/geometries which ARE sensitive?
E.g. I have 1000 props and want to move /props/foobar to
/props/Architecture/Interior/Bar_Stuff/Foos_Stuff so I can actually find things?

 If I am understanding your question correctly, you want to have a subfolder in props to put some of your stuff in. The answer to that is yes with versions 6 and up. (don't know about 4 or 5)

if you are wanting to rename your props folder to humperdink, than no. 

I hope I was able to answer your question, I haven't finished my coffee and am quite confused this morning.

Yes, that was what I wanted to be sure of. (I used "/$category" to mean all of
/props, /characters etc. which might have been confusing for people
who don't program in pseudocode :-), of course I don't rename those.)

Well the caveate to moving items in your libraries is that Poser itself will sometimes write Absolute file paths when you resave things to your libraries and if you move those items you will break them. Your best bet is to always check new saves in a text editor and change absolute paths to relative paths. IE:
C:Poser ContentPoser 6RuntimeLibrariesCharacterBorisFilename.cr2
Should be edited to look like this:
:Runtime:Libraries:Character:Boris:Filename.cr2

 Poser only writes absolute paths to something that is placed outside of a proper runtime folder.

If you add a texture that resdes on your doesktop,t hen yes, that WILL get a hardcoded reference to C:.....desktop but anything that is kept inside a runtime structure will keep relative paths.

EVEN when you use runtimes made for the occasion. (as an example I always make a runtime folder on my dekstop for assembling stuff before packaging. And I test out that by adding it as a regular runtime. Works fine and references are written correctly, too)

I've seen some products put the .obj and texture maps in the same folder as the .pp2 prop file. I don't know whether Poser will take too well to them moving.

If you encounter this situation I'd suggest backing up the guinea pig folder before trying to rename it, just in case.

Several pose files (inj/rem used for morphs) will refer to either custom morphs in their own folder, other inj/rem files, and so on.  Those will also be affected.

I would seriously recommend getting one of the software packages that checks and automatically changes references in the files so you can move thiongs around much easier.

 you can always add your favourtie runtimes as external runtimes. I find that is easier, then all the poses in the pose files apply to the figure in the figures library etc, and it only takes a second to add the new runtime after you buy it.
