lightroom classic delete old versions

[Lino H.]

Hello,  Will deleting the lrcat-data files of previous LrC versions adversely affect my latest version lightroom catalog V-13? Are there any precautions I should be aware of? Thank You.

The lrcat-data files relate to masks. You should be fine deting this not ending in v-13.

Thank you. I appreciate your help.
