This topic provides a brief overview about USB bulk transfers. I have come up with a simple protocol and will a little C app that should be portable.Each USB transfer is one packet, which can be up to 64 bytes if using bulk type. If you want to send more than 64 bytes, you have to use multiple packets. Once the file transfer is complete, you can remove the USB from the first computer and slot it into the second. Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. That's how you can go about transferring the files that you already have in here over to a stick really simple really easy to do. 【Bulk Flash Drives 128MB】128MB USB flash drives 100 pack, with 20 lanyards, double tested before shipping.
