Keeping track of "moved files"

Question

When importing pictures to the Aperture library, I usually do it by choosing to leave the files in their actual location. I understand that in so doing Aperture creates aliases of the files in its library. The location of my picture files varies; it can be on external drives or on the internal drive, depending on many factors.
But, whenever I change the location of a folder with pictures in it that I had imported to the Aperture library, Aperture looses track of the files. Is there a way to avoid this?
Thanks for helping.

Answer 1

Aperture does not use aliases to track the referenced masters. References exist in multiple text files, and probably in the database as well.
Examples of files that contain references (in your image's folder in the Aperture Library structure):
<filename>.apfile
<filename>.apmaster
You really should import files to where you want them or use the relocate masters function within Aperture.
