    Duplicate files

    This may not even qualify as a software item, but I would be interested to learn preferred programs or methods of locating duplicate files, mainly documents and photographs, on an XP system with multiple partitions.

    Re: Duplicate files

    There is certainly a lot of software around to do this kind of thing. There are also significant issues to bear in mind when doing it. In particular:
    <UL><LI>Are the detected dupes really exact duplicates?
    Some software uses a byte-by-byte comparison or CRC check, others use cruder methods like filesize or even just name. Just be aware of that and find out exactly what the software does before nuking files.
    <LI>Will removing a duplicate mess something up?
    Often a program will install a .dll or .ocx etc. in a particular folder for it to find. This may be a duplication of what already exists in Windows. However, removal of either might cause problems. Be very careful in removing such duplicated files.[/list]Maybe have a look at Space Checker 5 <img src=/S/free.gif border=0 alt=free width=30 height=15> version. Also, there are quite a few discussion threads on this Google Search

    Re: Duplicate files

    Thank you for the help Alan. The questions you added are roughly those I had myself, except that the files I'm looking for will not include system or program files. The suggested program looks like it might be just the ticket.

    Re: Duplicate files

    It's a while since I've embarked on that sort of exercise, but I also remember having cause to use file comparison utilities. There are several highly regarded <img src=/S/free.gif border=0 alt=free width=30 height=15>ware tools available. ExamDiff - Visual File Comparison Tool is a popular recommendation. Many more on sites like SoftLookup.com - File Comparison

    Even so, you can get some odd results. e.g. one Excel file I had was (IMO) an exact duplicate of another, but the compare program I was using found a difference, somewhere deep down in the binary structure. Again, just use your discretion and go slowly. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
