This is more of a puzzle than a problem.
My co-worker was having problems with a pack-n-go not saving all of the parts. He had placed a -x as a suffix on all the new part names and when he opened the new assembly only some of the parts showed the new -x file name while others retained the standard file name. So I thought I would try it and see if I could figure out where he went wrong. I did a pack-N-go to a zip file on my desk top then extracted the files. Looking at the folder all of the files appeared there and with the -xx suffix that I had added. I then opened the top level assembly and son of a gun many of the parts did not have the suffix leading me to think I was pulling in old files.
In fact, other than the main assembly none of the top level components showed the suffix but all of the components of subassemblies did.
So out of curiosity let's open subasselmby 860877 and see what we find.
Here 860877 shows the suffix even though it did not when in the top level assembly. And no amount of refreshing changes that. Apparently all of the files were saved and had the suffix added, but they just don't show it in the main assembly.
Does anyone have any explanation as to why that may be? It's not a show stopper, but it sure makes one doubt himself before modifying parts. I would try opening this file on a different machine, but I don't have one not on the network so it could still be looking there when opening.
