#2I personally found fdupes to be slower and more limited than dupfiles [0].
I switched to dupfiles about a year ago and haven't had any problems yet.

#3I used this when I was working on a product that used automated tests to upload files repeatedly during the day. The volume of test files was so great that it continually put pressure on the storage -- more pressure than the uploads from the actual users.
Fortunately the uploads were from a set of a few dozen static files, and de-duplicating the data via fdupes was able to drop disk usage by a factor of 20-50x.

#4Is this multiplatform? I think it's interesting how many projects forget to mention what operating system they target.

#5I did something similar to this a while back, called qdupe[0], written in Python. It doesn't do the deleting for you, but is very fast at identifying duplicates if you have a lot to compare. Based on the fastdup algorithm.

#6not nearly as fancy, but it gets the job done for me:

I found myself asking the same thing, and ended up finding a Python program:

I plan on giving it a whirl, to help me clean up my backup drive.

#8Yeah, I wrote something similar a long time ago in Python: https://bitbucket.org/panzi/finddup/src

#9It's not exactly clear, but I'm assuming this is some kind of automated hard-linking utility? Or does it use its own special magic? (filesystem type restrictions?)

#10I personnally use fdupes.pl:
http://www.perlmonks.org/?node_id=85202
Tested on many millions of files, works like a charm (though it can run out of memory on a 32 bits machine). I'm using the enhanced version here: http://www.perlmonks.org/?node_id=1099194 which has an autodelete flag and prudently ignore symlinks.
