Any relevant log msgs?

The format of a FileStorage file is platform-independent.  There
should be no problem moving an .fs file between Windows and Linux
boxes.

There's hope.

No way to tell from here.  When you make a copy from Windows -> Linux,
is it exactly the same size?  Have the same, e.g., md5 signature?  A
common problem when moving files between Linux and Windows is bumping
into _some_ layer that thinks it's doing you a favor by translating \n
<-> \r\n, and that's disastrous for binary files (which .fs files
are).

You shouldn't need to do anything.
