    As a newbie, I’m appalled at how many duplicate files I’ve already accumulated. However, how do I know which ones to eliminate? There’s no reference when you select a file which tells you where it is, so I’ve no idea of the ‘safe’ one to delete.

    yes i have the same question. how to know what we can delete in each tab? all of them??? the packages shows – almost all my packages (if not all of them) so i have to delete them? 😛

    I have uninstalled and reinstalled Ubuntu 5 -6 times because I either uninstalled something I thought was redundant, or installed something over something essential.

    So this program would be useful in pointing out potential problems if you choose to remove the files.

    After the last 12 hours of Ubuntu hacking, I vow never to uninstall anything ever again until I Google for potential hazards.

    Its a pity that the ‘official’ documentation is so thin on the ground. I have to say though it’s a great app, once you have worked through a few dummy situations. Before going onto live data. I’s been said many times before me, back up first is a very good idea. Backing up was a reason for my seeking out this app. I wanted to backup my pictures but I had so many dupes./ luckily I had just bought a new drive so I copied the folders/files over and did a dummy run, one copy left behind. even with a backup you will get clammy and nervous, so make a few duplicate files/folders in a safe placw and test drive until you are confident in your/app’s ability.

    thanks very much for these hints and tips!

    If you just want to delete the dupes then it is much more efficient to use FSLINT as a command line tool.

    Why not make a program equal to ccleaner for windows? That program is 100% safe to use with the default settings. If I knew how to program or make it, I would, but I’m not 🙁 Maybe ask the ccleaner team to make a linux-clone? or maybe someone has a better idea?

  8. tricky says:

    With a huge number of files to check, fdlint does terminate with a runtime error before any duplicates are found 🙁

    they do have something similar to ccleaner for linux. it is called bleachbit. you can find it in your synaptic package manager, googling for it or simply typing this into your terminal “sudo apt-get install bleachbit” it does many of the similar operations of ccleaner, ex. deleting browser cache/history. auto clean autoremove, bash history, broken desktop files, system cache, ect.

    Hi, The documentacion of the web site seems to me that it is quite complete ans easy to understand. I don’t know if we are talking about the same page but I got there though the link in the package search result, and then under documentation (anyway, here’s the link):


    Check it out. Cheers,
