There is no such thing. Per se all that stuff is independent and if something is missing, it will simply render black/ with color bars. either way, it's a moot point - you ahve not provided any useful technical information and we simply don't know anything about your file structures.
Care to provide any useful technical information about which technical information may be useful?
Wait, are you saying AE is linked to the Premiere Pro project just fine, but you can't remember where the actual Premiere project is located?
My AE machine is currently busy so I can't check this for myself, but can you right-click and choose "edit original" or something similar (in either the timeline or the project panel)?
Yes that seems to be the case. I've been editing audio in Adobe Audition from Premiere Pro and later found the the project I was working on had clips that were dynamically linked to After Effects, but those AE files were not the most updated versions. Now, the most updated AE files still exist in an AE project that I can open, but I cannot find the Premiere Pro project they are linked to. I've been right clicking all over the place but unfortuntaely have found no options like "edit original" or "reveal in finder."
