Instead of "removing" a folder with thousands of photos I went in to Windows Explorer deleted the catalog, the locked file and a few other folders. However, when I try to delete the folder with all the thousands of previews folders in it I get a message telling me that I can't delete them because they are being used by another program. I don't have Lightroom open when I try to do this so my question is: how can I simply delete those folders from my hard drive?
Do I have to un-install Lightroom to do this? Hopefully not.
