Increase copy file speed from PC to device.

May 31, 2013 at 5:54 AM

I notice that copy file from PC to device is very slow when the file size is large (~6-7MB) as compared to copy and paste file directly from Windows Explorer to device.

I change the FileCopyBufferSize to 256K and 512K, 1.5MB takes ~12 seconds. 256K is optimum setting I find out from my project, e.g.

mRapi.FileCopyBufferSize = RAPI.EFileCopyBufferSize.MaxSlice_256K;

Is there anything I can speed up the file copying speed again?
