ACK.

Win32 filesystems store long filenames in Unicode (UTF-16), I'd not 
expect problems in addressing files using UnicodeStrings.

I'm not sure, but aren't DOS filenames restricted to the OEM codepage? 
There exists no direct correspondence between long filenames and their 
8.3 names, which may have any number after "~", depending on the 
contents of the directory. Such names never should occur hard-coded in 
an application.
