I would like to have an application for comparing contents of two folders to check if they contains same files. For Windows or Linux.
I've tried WinMerge.org, however, it compares folders for identical structure - that is it looks for contents of folders of 1st location only in same relative path folders of 2nd location.
I want an application for each folder/file in 1st folder to search for same name/time/size entries in 2nd folder's all structure / all subfolders. No need to verify contents of files now and no need to have merge functionality, just a report.
Ideally for each subfolder in 1st folder when some files from it found somewhere in 2nd folder, it would write line like 35% by size, 45% by quantity match found and if not 100% then list of all found files/subfolders in results tree branch.
