I thought Lightroom kept all those changes stored right in the catalog?

So, if somebody says to you, “Send me the RAW and the sidecar” you know they need your RAW file and that. You’ll hear it called either an xmp sidecar, just a ‘sidecar file’ or simply an xmp file.

xmp file for the RAW file with the same name, but its file extension is. It’s a separate text file that holds any edits or metadata changes you made to your RAW file. So, after some questions, I thought today I’d do a quick Q&A about XMP, when you should use them, and why in most cases you shouldn’t).Ī. xmp files each time you make an adjustment in Lightroom and I mentioned that most Lightroom users should probably turn this auto writing of xmp files off. #7 was about turning off having Lightroom automatically write. This is a follow-up for reason #7 from my post on Monday called “If your Lightroom is running slow, it’s probably one of these seven reasons” ( here’s the link in case you missed the other 6).
