2018-01-27 20:38 AEST by Arthur Barrett - It may be a security issue to allow .exe files to be checked in (indeed - the same may apply to unix/linux 
'executable' binaries - or anything with 755 'permissions'.

It may be useful to prevent the server from both checking out or even checking in these files (because they 
may end up in the PATH - especially DLL's) where files can be executed or DLL's loaded from the 'current 
working directory'.

A better solution would be to use 'permissions' and if the .exe hasn't been checked in with executable 
permission, don't check it out with executable permission.  But that only works for partitions like NTFS, not 
FAT (which are still really common).
