Cleaning up data base files and old...

I installed LR version 1 and reimported all new photos. I noticed that for some reason I have several folders of backup and libraries in my lightroom file folder some nested within others. I would like to remove the old files and keep only the latest ones. I am not sure I know how to identify the latest files to keep or delete. I then would like to back up latest files in another location. Any help would be appreciated.

Thanks

Jim

OS?
%26lt;br /%26gt;
%26lt;br /%26gt;Lots of ways using a combo of LR and OS. Select an image and have it reveal where it lives. Note the location.
%26lt;br /%26gt;
%26lt;br /%26gt;Make a change in a file, export the metadata, and if a folder you are looking at doesn't have any recent changes, it isn't the one in LR.
%26lt;br /%26gt;
%26lt;br /%26gt;Another safeguard is to zip the file, instead of trashing it. That way if you later find LR is counting those images as part of its db, you can restore.

I am running Windows XP, sorry forgot to mention that. The files I am talking about are those that Lightroom stores in the Lightroom folder in My Photos, called backup, library,lightroom previews, etc. I tried to delete all but what I thought were the current ones, but I had to restore them.

Thanks
