Clean Lightroom

[ElwiraKotowska]

I apologize if my question was alredy answered.

I have 3 catalogs from the same days.

Does I need keep all of them?

Thank you in advance for your answer, elwira

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Lightroom forum so that proper help can be offered.

[moved again by moderator. This belongs in Lightroom Classic, not Lightroom ecosystem]

These are not three catalogs. There is one catalog, which is the .lrcat file. The Previews.lrdata file is a helper file that belongs to the catalog. You should not delete it. The .zip file seems to be a catalog backup. Apparently you let Lightroom made a backup on quit. Making backups is a good idea, but it is better to let Lightroom save them on another disk if possible. You can choose the destination in the backup dialog.

These are not 3 catalogs. Only the .lrcat is a catalog. The other is the previews, which LrC uses, and a .zip file, which I don't know why it is there, probably something you did.

You need the .lrcat file and the previews.lrdata file. I don't think you need the .zip file, but as I said, I don't know why it is there.
