DupLichaSe is a very fast Duplicate File Detector that uses inductive heuristics to detect duplicate files very fast; based on content! DupLichaSe stands out from EVERY other Duplicate file detection Software because of it's graph based semi-automatic selection system. ... after finding 100s of duplicate files, do you have to go through some manual and possibly laborious process of deleting the duplicates? ...or is there a way for the Software to learn and do most of it for you in a SAFE and RECOVERABLE MANNER? YES!! There is!! ...This Software will ALSO help you and delete duplicate files, after you must have taken action on a a FEW important files(i.e large files that are duplicates). ++Thanks to its trivial Graph based suggestion System

Many times, developers (or even, normal users) run into an issue of searching for a resource that is inside a zip. Worse, that resource is inside a zip which is itself inside ANOTHER zip (i.e. nested archive). Possibly you need to verify whether a particular resource is present in an ear or you want to know part of a file name but don't know which zip/jar on your hard disk contains that class file. zfind solves this problem. zfind is very fast and it works on most common archive/compress files. Apart from GUI and command line, it also provides API support which let's you use it in your java code as a 3rd party library. Thanks for using, and if you find any bug, do post a ticket or discussion topic. I can't fix anything if I don't know the problem :) **Check Wiki for USAGE details
