I am using FindStr (Windows Command Line / DOS) to search for a string in all files in a directory (and sub-directories).
It works fine for the most part, but it sometimes comes up saying that it cannot open some MSG files (moved from Outlook to a network drive).
It works fine for most MSG files - just a few that it 'cannot open'.
I have opened those files in Outlook, and they open no problem, so I am reasonably sure that its not that the files are corrupted or anything.
The string we're searching for probably isn't in an MSG file anyway, so I could just exclude that file extension, but I am curious why it might be failing, and if I do need to search such files, it would be good to know what the issue is.
