#9 Exclusive Lock Used When Reading Image Files

[DaveG]

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?

Thanks.

I'll look into this over the weekend. Should be a simple fix. I pan on pushing a point release for testing soon, to test the conversion to the new build environment, installer (zip will still be available), and a few other fixes.

Thank you. It'll help me a lot.

MOved to Feature Request as this isn't really a bug (at least not in our code). It appears to be the way Windows handles files that are read/write.

No status change. Still targeting for 1.0.

commit 5200e2f contains the fix for this - allows for multiple read access for a source file.
