    Quickest way to copy files


    I have an ext. HD that is on it's last legs, I need to copy all the files onto a new ext. HD. Is there any faster way than Windows Explorer?

    It's about 1TB with about 2000 files.

    I'm on Windows 10, 22H2, .3086

    I think FastCopy is the best choice for the job.

    Fastcopy is about 4% faster than Robocopy which is about 4% faster than W.E., when copying 17 files(18 GB) from one drive to the other.

    And once you get the hang of it, it is easier than Robocopy, there is a learning curve with both programs.

    Thanks for you inputs.

    What /MT: values did you use in that comparison?
    They can make a lot of difference.

    Dennis,

    I used the default /MT, will try it again with your best number, thanks.

    If you have the time, compare repeat runs with different numbers to see what works best for your circumstances.
    My best number your best number.

    Dennis,

    Using your number and logging to a file with a 20 GB folder with 20 files Robocopy had a 3% better time (MB/s) than Fastcopy (Using Fastcopy's default settings).

    I'll finish up using Robocopy with different numbers, report if there's any significant differences.

    I varied the MT numbers from the original (8) up and down to find the optimum, 1 thread was optimum, twice as fast as 8 threads.

    Now the rest of the story, the computer I used is not the one listed in my profile it's a 12 year old Acer Aspire with an Intel Pentium CPU. I have no idea if that effects the thread count or not (way above my pay grade).

    My original question has been answered, thanks.

    I also have to use a very low thread count when I sync to one very slow computer on my network.
    The others, even the very old ones, are alright - it's just this awkward one.
