Quote - I had Poser 8 on a portable harddrive, which is K: and just put it on an external drive, which is J:. Now, when I open Poser 8, none of the libraries show because the Poser 8 was previously mapped to K:. I can't rename my J drive to K drive because it would affect several programs on it, but I just need to know how to get the Poser 8 to recognize the libraries with the new drive letter. Thanks for any help.

Fixing Poser is relatively easy, just edit the LibraryPrefs.xml file to reflect the drive change for those Runtimes that need it.

You are however going to run into problems with any files that have full paths that refer to the older drive.
The only permenant solution to those is to fix them up when you find them.

You should also make sure that the assignment of drive letter is permenant (or at least as you can persuade Windows to make it).
