Calibre refused to delete book

[Dan Weber]

After converting an epub to rtf when I tried to remove book error message popped up

calibre, version 1.6.0

I deleted files using File Explorer. File did convert. I use Win 8-64 bit. I have ActiveState ActivePython 2.7 (32-bit) installed. First problem in 4 years.

That error indicates that one of the files belonging to that book was
open in another program, which is why the delete failed, most likely the
file was being scanned by your antivirus at the time. I have changed
the code to first check for that condition and refuse to proceed if the
file is open in another program.

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.
