Fetch upload is smaller file size than original (4 posts)

    I am uploading several large zip files to a remote server. I'm wondering why the files show up one size (i.e. 507 MB) on my computer, but a smaller size (484 MB) on the server once they are uploaded. Is this normal? I tried going to Remote>Put and resuming an upload after I was disconnected, but nothing happened. It appears that the whole file is there, because my client got it in its entirety.

    Hi Sarah,

    I would recommend using the Get Info command on the file on both your computer and on the server. I suspect you will see the same number of bytes.

    The problem is that there are two common meanings of "megabyte" or MB. The traditional definition is that a megabyte is 2^20 (2 to the twentieth power), or 1,048,576 bytes. The other definition is that a megabyte is one million, or 1,000,000 bytes. [KB and GB also have two, slightly different definitions.]

    Apple recently switched to using the "million" definition, so it appears that your file is about 507,000,000 bytes. Fetch and many servers use the 1,048,576 definition, and under that definition 507,000,000 bytes is about 484MB.

    This difference can make comparing file sizes a bit trickier, especially with bigger files. I recommend comparing the exact number of bytes, rather than the number of KB, MB or GB.

    I hope this helps,

    Awesome. I was wondering what was going on, I'd heard that Apple had made a switch over to some new standard of size. The idea of just checking the bytes is perfect. thanks nerds!
