I have a regular habit of using Win32 Disk Imager to write the same image to more than one SD card at a time (up to 8 at once). Doing so requires opening multiple instances of Disk Imager, which is fine. However, Disk Imager always uses an exclusive file lock (which is unnecessary if it's only reading the file). To work around this, I'm forced to make a copy of the image file for each instance of Disk Imager I open, which wastes a great deal of time.
Could you please set Disk Imager to use a non-exclusive lock when it's reading an image file?
