Originally posted by PKMike Does LR5 have similar tendencies with its organizer? I hope not. Sounds like that may be the one to go with.
The only issue I've run into with LR5 is that it's ridiculously difficult to fix "missing" photos, if you happen to move any photos without doing it precisely correctly inside lightroom. I have about 43,000 photos LR considers "missing" from when I moved a hard drive and then backed some of the files up to NAS.
That said, if you simply do this when you first install Lightroom, it will never really be a problem that will matter:
For every catalog you create (if you ever make more than just the initial one), go to Catalog Settings > Metadata> Automatically write changes to XMP.
If you do that, you won't lose much of anything if your catalog gets corrupted or you screw up like I did while moving to a new hard drive. You can just delete the files from LR and reimport them, and any edits you made will still be there.
If you don't, well, you still won't lose any files, just all the work you put into editing them. Or you'll have the tedious job I have, of reminding LR 1 folder at a time where everything is, and then hoping it will find the rest of the files in that folder.
