    This is still at v1, I look forward to v4, but at this rate, it will take forever to get to v2.

    I suggest NOT just loooking at the competition to decide what features to incporporate in the program, but I suggest looking at USERS and what we want and expect to be able to say to our computers when searching for duplicates:

    — Hey, computer, did I mix up and save some files to
    – “C:\Install\vendor name …”
    – “C:\Documents\vendor name …”
    – C:\Users\MyName\vendor name …”
    and good old root
    – “C:\vendor name …”?
    In other words, search my WHOLE COMPUTER computer and tell me where I’m burdening myself with unintended duplicates OR duplicated storage LOCATIONS that probably would be better if pulled together into ONE directory structure. Look for duplicate DIRECTORY names, not just duplicate FILE names, even suggest that directory
    – “…\John C Smith\…”
    might match directory
    – “…\John Smith\…”
    or directory
    – “…\Smith, John\…”
    and offer to move and combine them to a preferred directory, even though there are no duplicate files, learn to consider SYNONYMS as well as DUPLICATE DIRECTORIES.

    — Do I have duplicate filenames with DIFFERENT contents, and I’d like to pull them together and RENAME them in order, such as
    – “C:\Documents\2023\My Daily Journal.doc”
    – “C:\Documents\2024\My Daily Journal.doc”
    and I want to KEEP THEM BOTH, but when I pull them together into
    – “C:\Documents\Journals\…”
    I want to rename them intelligently:
    – “My Daily Journal 2023.doc”
    – “My Daily Journal 2024.doc”.

    — Do I have installations for 64-bit programs in
    – “C:\Programs\Vendor\…”
    AND the same as a 32-bit programs in
    – “C:\Programs(x86)\Vendor\…”?
    I’ll uninstall the 32-bit versions of programs if I have 64-bit versions installed ( like IrfanView, for example ) – help me find and do this.

    — Do I have multiple copies of one image where there’s the ORIGINAL and then all different smaller sizes of trying to make it small enough for a web-share, and it took me 7 tries to get small enough, and I have 6 ‘inbetweenies’? Only the ORIGINAL and the FINAL copy are what I’d like to save, help me do that. Do I have TIF lossless copies of JPG lossy originals? Do I have JPG lossy copies of JPG lossy originals? Compare compression schemes and tell me which file has the most ORIGINAL information. Offer to pull all copies of the same image into the same master directory scheme, such as pull smaller JPG copies of one particular iamge found in in
    directories into the master directory where the ORIGINAL image is stored, and rename them intelligently:
    – DSC9987654-original.JPG, <– to big to share
    – DSC9987654-2048×1365-86%.JPG,
    – DSC9987654-2048×1365-65%.JPG,
    – DSC9987654-1024×768-85%.JPG,
    – DSC9987654-1024×768-65%.JPG,
    – DSC9987654-512×341-65%.JPG,
    – DSC9987654-512×341-16-colors.PNG <– finally small enough,
    and so on – I only want the first one – the original – and the last one – the one that was successfully shrunk to the right size for sharing, those are the two that I want to use over and over again.

    — Do I have multiple INSTALLATION files for ONE program? I only need the most recent/highest version, such as finding and offering to eliminate the prior installation files for
    – DupInOut v1.1.3.0,
    – DupInOut v1.1.3.1,
    now that I have
    – DupInOut v1.1.3.3,
    and so on for other program's installation files. For another example, I have dozens of old copies of Java that I'll never use, they are all different sizes and names, but I only want the latest/highest version – make DupInOut smart enough to look for THAT.

    THIS is what it takes to get to v4 of a program.



    + PROS: Rasonably quick and accurate, lots of controls, big clean interface.
    - CONS: Does not have some important auto-selection schemes, such as "keep copy with shortest path or shortest filename" which would eliminate "file (2).exe" in favor of "file.exe", we have to manually select every "(2)" file. Image search does not show two images as large as possible next to each other on our BIG screens so we can see the difference. "Compare two directories" does nto seem to have an option to "prefer files in directory 1"-kind of selection, so what's the point of having a special 'feature" versus just comparign files ani whatever directories we add to the "compare" list, and if we add only 2, why nto have a "prefer files in directory ___" option?
