Bug Description

When selecting an image from a network share (\\host\path\file.img) and clicking "Write", the tool reports "An error occurred when attempting to get a handle on the file. Error 3: The system cannot find the path specified."

This is due to the use of the "\\.\" location prefix in getHandleOnFile() in disk.cpp. A quick-and-dirty fix would be to check the incoming filelocation string for two leading backslashes. If they exists, don't prefix the filename with \\.\

I'll look into this and see if I can come up with a complete solution for the next point release (coming soon).

I would like to point out that in my own tests, I have had issues with flashing a device from an image stored remotely, and i have 1Gb network at home. This is all Linux based using dd which works in principle the same way as Win32Image Writer.

Have you tried mapping the network share as a drive (i.e. z:) and tested? If it works ok, then I will pursue this further. If you run in to write buffer issues, then it isn't worth pursuing.

I have no problems writing an image hosted on a mapped network drive. I'm only dealing with small (<1MB) images at the moment, though.

Just tested writing from a 512 MB image from a mapped network drive - worked fine. Write speed was reported at ~5.5 MB/s.

Also tested reading a 4GB flash drive into a mapped network drive - also worked fine. Read speed was reported at ~13.5 MB/s.
