Due to my father's file mismanagement over the years, he has multiple copies of same files - worth hundreds of megabytes - copied into different directories resulting in a few GBs of HDD occupied needlessly. Is there a software I can use to locate same directory and/or file and help in sorting them out?

In short, I need something that:

  • finds copies of the same file and folders
  • informs me of files/folders that have the same name even if their contents are not

Solutions not specific to a particular platform preferred, but not an important issue.

sudo apt-get install fdupes
fdupes -r /directory > ~/dupes.txt

This will look for duplicate files (by calculating and comparing their md5 hash values) recursively in /directory and write them to a file named dupes.txt in the user's home directory.

Any GUI frontend? There's literally hundreds of files copied, and it won't be easy to check them one-by-one going by each entry in the text file. –  Oxwivi Apr 22 '11 at 6:35
    
You could use a shell script to move all files in the text file to a temporary folder (or to delete them right away - not recommended). I wouldn't know of any GUI though. –  nem75 Apr 22 '11 at 12:33
    
I need to examine each of the duplicated files... –  Oxwivi Apr 22 '11 at 14:38
    
Really? If fdupe finds duplicates they are 100% byte identical. Would you still need to check them? –  nem75 Apr 22 '11 at 17:04
    
You got a point, but the directory each of the copies are in is important to sort it out. –  Oxwivi Apr 22 '11 at 18:36

You might want to try fslint if you need a GUI.

sudo apt-get install fslint
fslint
