I'm new to UltraCompare, and you would have thought it would have solved directory duplicate comparison/differences by now. A way I have used in the past, before buying UltraCompare, was to:
a) run Karen's Directory Printer on the uppermost directories you want to compare separately, saving the text for each directory with subfolders option ticked to disc using options 'path/file name/size/modified date/md5 hash'. These can be as massive as you like.
b) run Excel and import the two or more different text directories with tab option and no quote marks round text option. Then sort according to what column (file name, size, md5 hash &c) you wish to find same files. The path name is important because it'll tell you which directory the duplicates are in. This is brilliant but MANUAL and LENGTHY unless you know Excel well enough to find similar files auto-wise, which I don't, yet. Remember when sorting to select all the entries first, then decide which column(s) to sort on: if you don't do this the data will get muddled.
I have found that UC can't tell you where a file in one directory is in the second. As I sometimes might copy a file out of a sub-folder into another named sub-folder there is no way, apart from the above for bulk comparison, it will do this. Just, boring, use windows search and then use the text compare. But that's almost as tedious as doing what I've just done in the past above.
Any way round this in more recent editions?
