  1. I’ve used duplicate files deleter software that detects duplicate files and it’s quite user friendly. It can detect file format. You can delete the whole files at one click or can delete desired one.

  2. My first computer was an 8088 Epson Equity II, with a 10 megabyte Hard Drive with two 5.25″ floppy disks. 8 mHz and 10mHz with turbo with 4 megabytes of RAM using DOS 3.0 and Winblows 2.0 and eventually 3.0 and finally 3.xx for workgroups.

  3. the first computer that i remember checking MB size (when i was a kid i didnt care, just played old dos games !XENON 2!) was a 1GB PC

  4. How do duplicate file finders work on networks? How do I know if I’m deleting a file on one of my other computers?

  5. I had so many duplicate files in my system which are taking so much of my disk space… Well i search on google and found the most advance duplicate file finder…

    Reading back on more of the comments, as a second addendum , I recall my friends buying other ( remember Epson marketing a puter?) and getting optional 20 MB drives thinking it was lunacy to buy such a huge (rofl) 110 drive, adn I trying to get Gateway to build it with a SCSI drive back then. How oh how has technology changed over the course of a short last 2 decades, and how many people sdo not realize the overall quality of life these advancements have given them– GPS, Cellular phones, cable, satelite and HD TV — and the bes for last — LIFE — lazer eye surgeries from opening drain holes to relieve eye pressure adn lazik, to robotic bypass surgery to eliminate sawing one’s sternum and reduce the trauma on one’s body – after the computer assisted scans from stress tests- which used to take 45 minutes and now take 15. There has been nothing more amazing to me in this life so far as to the endless application of techno and it’s ability to use it to advance itself in more and more everyday applications — boy have we become spoiled– and taken too much for granted. 🙂

    Oh yeah and imagine buying and seating 9 dip chips for each meg of memory you added- those were the daze- glad they are gone lol

    Hahaha so you think your drives were small — lol 110 Mb mfm drive with my first Gateway 386 based computer– and later bought a second one for $425- HOw many 2 Tb drives will that buy today?– considering searching the web for best price ( a luxury not available then – unless you consider the command line beginnings on Delphi, Genie, or CompuServe.

  9. At work our first mainframe disk drive was a Bryant disk. I cannot remember the storage capacity but the platters were 36″ diameter and the read/write head actuators were made of wood. When doing a big sort it would dance across the computer room floor. We had to re-write the sort program.

    1983 KayproII, a cheap (a bigger and better) version of the “transportable” Osborn. 64k CP/M with no hard drive. 80 character x 28 line green screen. And oh yes, the 4.25″ original floppies were 192k SS/DD (“single sided double density). Nice non-wisiwig (sp?) word processor, spreadsheet and database. I think the 8086 processor operated at something like 3mhz.

    It was a serious office machine before DOS. We bought several more until Kaypro went under cerca 1987. I still have a Kaypro 2000 laptop boat anchor with no hard drive. Worked great when I last tried it about 5 years ago.

  11. My first hard drive held 20Mb and had 2Mb of RAM if I remember correctly. I do remember that there was no color and the screen was black with white text. This was, of course, pre-Windows.

    My second hard drive had 500Mb and 4Mb of RAM memory. I bought the 300 over a 300 because a computer geek friend told me that I would never need more than 500Mb. Boy was he wrong. I now use a 500Gb hard drive and a 4Gb RAM and I am thinking about adding a 500Gb portable “Book” hard drive. Things have really changed in a very short time.


  12. My first hard disk was a $15,000 5-meg removeable hard disk drive on a Wang mini system. My first OSI computer was dual 8″ floppies. My Vic was a cassett tape drive.

    My first hard drive was a 5 mb used, and it cost me $200.00. My next was a new 30 mb hd and it cost me $300.00. Quite a change in about 25 years.

  14. I used Duplicate File Finder recently to sort thru over 800 duplicate files after I restored a Backup after my laptop’s Hard Drive crashed. It worked great and allowed me to Reverse Sort the files so the older version was the one that would be deleted when I checked all.

  15. Smoky999, In poker terms, I’ll lower you to my first computer, an IBM 1401G w 16k and I don’t remember drive size, but I’ve left more bits of chicken on the table than it held.

    The first machine with “memory” was a Sperry Rand 1004 that used a plug-board and had 961 BITS of memory.

    Prior to that it was 407/514 PCAM stuff. Yup, I’m that old!!! 😉

  16. My first hard drive at work was 20Mb.

    My first one at home had NO hard drive. I had to use the 5″ floppies to boot up DOS 3.1. Some years later my daughter gave me a computer with a 40Mb hard drive.

    I currently have a 40Gb hard drive with a 500Gb removable hard drive.

  17. The first desktop computer I trained on at university was “state of the art” – a Commodore PET with 8K of RAM and an “audio cassette” tape drive – no hard drive. At the same time, I was using an IBM 360/40 with keypunch cards and a 10 Mb hard drive that was mounted in the Systems department – it was a 12″ platter!

    Five years later, I was using a (new) PC-AT running DOS 3.2, with an amber 11″ screen and a 20 Mb internal hard drive – retail price with 24-pin dot matrix printer, $10,200.

    Yes, we have come a long way…

    Chris, re your comment on HD size. my first was a 10Mb drive with a 4Mb ram and a turbo boost to 8 Mb. We have come a long way in the last 28 years
