Thank's for all the assistance everyone....
Mike - If I'm understanding you, you're asking the root path? If so, this is the catalog path...
Catalog name is...
Lightroom 4 catalog.Ircat
In this catalog, I have about 20 subfolders, half of those are folders with the question marks and missing pics. Previews are still present in the library though.
Cary - Great idea and thanks for the contact! The folks over at the LR flicker group have been helping, but so far nothing conclusive. I'll check the LR forums Okuna mentions also, thanks Okuna
Erik - I've tried searching filenames through the finder search. Problem is, because of the way I import daily, I have files with the same number designation. Just different dates. As far as I know, and I'm a Mac dummy for sure, is that the search feature in the finder is the only one? As far as "Why" they got moved...maybe we'll figure that out if we find the missing files? I still think about the virus angle too.... I mean, I've never seen a computer do what it did that night. Creating and deleting multiple temporary folders on my desktop...just while I was watching and not doing anything?? Is that a normal Mac thing??? It was that next day the issues popped up...so just a thought.
David - I've always imported them using the import function in LR straight from the SD card. Now, of course, I know to do it differntly. Like I mentioned though, I've been doing it this way for 5 years and this is the first time I've had this kind of issue. I utilize the same couple of SD cards for my whole trip, which means basicly I'm importing then reformatting the cards daily.
Thanks again guys!
