What can/should I move, and what do I leave alone?  I tried moving the whole thing, but then Poser does not start (Poser 7 that is)

I have moved all my Daz content to an external drive, due to the amount of filespace.

Wanted to do the same in Poser.  My guess is that I move:

RuntimeLibraries
RuntimeGeometries
RuntimeTextures

from Program FilesefrontierposerRuntime

...to external driveRuntime

Is that right or is there more I can/should move?

you are right, you can move anything thing thats in the root of the runtime directory (except anything thats in the python directory) and as long as you set the external runtime directory in poser it should reconise the files...

I would say the safe directories to move are the following geomitries,  libraries, Lipsync, Textures...

Though saying that, even if you move something poser needs and poser cant find the new file location the program will ask you to manually find the file... if that happens, you just take the file name posers looking for and do a manual search in the alternate external drive file structure

Thats what I thought, but on startup it says "The libraries folder cannot be found or created"...I need to ack that twice, then it all starts, though I then have to point it to the remote library.  Is there a way to set the new default to the other library/drive?

when poser starts up it tries to load up the default scene, which should load up the el'standard poser man which willl require the location of the default poser people locations... a way around that is to setup a new blank poser startup scene..

Do the following...

load up poser.... it will probably ask for the locations of files... do this...
Once poser is completely loaded, delete the poser guy in the preview window... now go to the "edit" drop down menu and click on "general preferences" a new window should appear, in the "launch behavior" part of the window select "Launch to prefered state" then click on the "set prefered state" button, this will set poser to load up a blank scene on startup and avoid any error messages that will be encountered....

also i should say that you can also create a "libraries" folder in the default install runtime and that should also aid in avoiding any error messages that occurr !

The most critical folder that shouldn't be move would be your Python script folder.  It is sensitive to location and will not work properly if removed from the core.

Poser already remembers the last runtime you used when you shut down Poser so it will restart in that runtime next time you start it. And Yeah, even though you can safely move the libraries, geometries and texture folders. It doesn't hurt to recreate some empty ones manuallty using your file manager before restarting Poser the first time after  the move.

OK, thats working!  Thanks all.  I had a problem at first, but I realized that the service pack install reset my preferred state stuff.  Thanks again for your help!
