Github for Windows may delete your files from disk if you commit them while a file browser is open.

I sent the following message to github support on 24 Feb but have
not yet received a reply. I will update this post when I do.

I am on Windows 7 32-bit, using Github for Windows v 1.0, with
Cubic Explorer as my file browser.

I added some files to my repo using a file browser, then committed
them using Github for Windows. When I attempted to sync, it failed
with the error that the files were locked by another program such as
Visual Studio. That's fine, but it also *deleted all of those files
from the disk*. This seems like a huge flaw. I don't even understand
how a "locked" file could be deleted in the first place.

I was able to repeat this problem several times. The file browser was
the only program that could have been reading the files at the same
time as Github.

if you commited them, just check them out back. no big deal.

To drive this perfectly fine working car, first let somebody crash into it, then repair it. no big deal.

mdirik: The commit failed. Remember?

no, because you didn't tell.

what i understand from this sentence is commit is done and push is failed.

@femaref checking things out from a scm is nowhere near to repairing broken cars.

It's a stupid proposition in both cases. An SCM shouldn't delete files unless asked to.

No, they both failed. After the error message, the commits disappeared from the history: https://github.com/dbb/skyrim_ref_books/commits/master

Notice how "Add original book files" only appears once? These were the files that were deleted.
