It might be that the OP is referring to pose files that call other pose files to do some work using a "readScript" statement. Like the INJ and REM poses of the Millenium 3 figures.
The first version of the V3 MakePack assumed that the end user did not move the !INJ and IREM folders within the Pose libraries - so they didn't work when I moved those to a more sensible place in my P5 runtime.
Later versions of the V3 MalePack didn't call the library poses, instead they called the ChanVis and Delta poses that reside outside the Pose library directly, which is a much better solution.

To answer the question: the V4 poses do not suffer from that original V3 Male Pack problem. So you can move all V4 pose folders around within your Pose library structure. No problem.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
