I find the "Move files to organised folder" feature very helpful and always use it once I've got things properly tagged. So I thought I'd try out the "auto-organise media files" checkbox so I wouldn't have to remember to do this manually, but I've been having a problem with it.
It notified me just now that various files were no longer there and asked me whether I wanted to remove them from the library. I'm 100% sure those files were there before enabling this feature, and they were appropriately tagged—as I said, I already used the "organised folder" feature for my whole library before this without any problems—but now they are indeed gone: not there where they should be, not in the recycle bin, and if they've been moved to some other location, I can't find them. This is some full albums and some random tracks—I can't really discern any logic to it since the files are gone now, but maybe it affected files of a certain format? Just a guess though.
Another possibly relevant factor: I was syncing the whole library (~35,000 files) to my phone using the wired sync feature when this happened. Because it's such a large sync, I was doing it overnight, and when I woke up this morning I found my computer had gone to sleep, aborting the sync. So I'm wondering if the interaction of the sync, the auto-organise, and the computer interrupting them by going to sleep could have caused this somehow?
I could be misidentifying what's causing the problem, but it seems to have happened once I turned this feature on, so it's my best guess for now. If anyone has any other ideas what would have caused these files to disappear, please let me know. I've turned the auto-organise feature off now, anyway.
My other question: is there a quick way to see all the files in my library that seem to be missing? They're marked with that exclamation point warning symbol in the interface, but I would like a way of showing them all in one place so I can see which ones need fixing/redownloading rather than attempt to trawl through my library and find them manually.
Thanks in advance for any help you can offer!
