    high ram usage during file transfer


    in window 7 it uses maximum 2gb of ram when transfering big file, say an example a movie size of 8gb. now in windows 8 it seems it uses 6-8GB its as if file is transfered into ram first and then slowly copy into targeted disk. just what is going on here and why microsoft decided to do this? if power goes out then all the files is gone and the entire process is actually slower imho.

    is there anyway to disable this? or revert it back to similar what 7 had?

    Try TeraCopy. See how much ram it uses and benchmark the transfers. I've only been on W8 a short time. But it seems like a lot of resources go into making that pop up file transfer graph. Using TeraCopy my file copy is much snappier.

    Haha Miles beat me, yes Teracopy - But shut off any AV programs while using it, if a Virus is detected while a Teracopy is running, it fouls up the copy. But Teracopy can be resumed if you are copying a whole folder to a new area.

    In my case "it" is the PC.

    Sometimes my AV mis-diagnoses a file as a virus, and when it does that, it deletes the file when it comes up in the Teracopy Queue. I have a gargantuan sized "exceptions" list heh.

    For me they're alright as scanners. But running a real time shield is like taking a shower with a raincoat on.

    is it just me or teracopy is slow with big files? large sequential file seems to be very very slow for some reason..

    It sounds to me like Windows memory maps the large file during copy. You're likely not going to match it with small buffers. TeraCopy author was around for support either via blog or forum. Also there are other copier applications that may provide better throughput on huge files.

    TeraCopy and others too allow you to choose which copy to use during drag and drop. If you want slow/measured copy in the background or full blast resource intensive copy in the foreground. Naturally everyone wants super fast copy using hardly any resources. But realistically there's going to be a trade-off. Try killcopy and some of the others too.

    Edit: For NTFS partitions see the fsutil command. You can do some optimizations. But I think they mainly benefit copy of many small files.

    thanks for the help. btw, teracopy doesnt have multi thread copy like richcopy does it? I dont see the options but doesnt mean it wont have it, or does it not have it?
