On my laptop (Windows 7) I have two rather similar subdirectorys in my lightroom folder: "Lightroom 5 Catalog Previews.lrdata" and "Lightroom Catalog Previews.lrdata". Now disc space runs short and I want do do a clean-up.
Are the Lightroom 5 Catalog Previews unnecessary remainings of my former Lightroom installation?
I would like to delete them (60GB) without generating the previews again.
Is that possible?
You can safely delete these files. Lightroom will regenerate previews when it needs.
