    I recently picked up a USB Hard Disk, I plan on copying large files to it (for example 20gb VMs), I am wondering whether or not finder can copy files as large as 20gb one at a time because the last time I tried to do this on a USB Stick, the file transfer would either freeze or would end up taking way too long to transfer and in the end I had to pull it out and having to reformat it. DOes anyone here know if such things will happen again copying these files?

    There's always going to be some level of risk, but shouldn't be an issue. You could also use Terminal if you want to do that. There isn't many other options.

    Code:
    cp -v path/to/file path/to/destination

    I'll try that, is there any indicator of how much is done?

    The -v means verbose, but I can't remember if it gives progress or not. It may only give the file name. I know some command line commands do give progress, like rsync, which is an alternative to cp.

    Code:
    rsync --progress path/to/file path/to/destination

    Make sure you format it to HFS+, FAT32 won't handle files that large.
