My c drive is a small SSD. And the lightroom folder with the previews is taking up close to 80GB!!

Help!

It says I should have the previews on the boot drive. The photos themselves are on a 4TB drive.

I need the space and I don't have anything else to purge.

Suggestions?

And if I move them off, do I have to move them through lightroom (like you have to do with the photos)

Thanks!

First thing to check is how long you are keeping the 1:1 previews. If you are keeping them longer than you need to, you can reduce that time and greatly reduce the number. The 1:1 previews are the largest of the files, so that would gain the most space.

Pretty good discussion of the drive space issue over in the Lightroom Queen forum (here ). The use of symbolic links looks interesting, but I have never ventured into such territory myself.

Any use of a link as a redirect would incur the same penalty as moving the catalog off the fast drive. Moving the catalog to a rotating drive will incur a substantial penalty in response time, however the real impact on the responsiveness of the interface would be up for debate. There's no reason not to try it. To do so:
- Quit Lr
- Copy the catalog.lrcat, Previews.lrdata, and (if present) Smart Previews.lrdata files to a folder on the rotating drive
- Double click the catalog.lrcat file in the new location; it should launch Lr with that catalog open.
- Test the performance of Lr. If it is acceptable, you can then delete the files in the old location.

Thanks -- I look into all of that!
