Description

GetFileInfo() seems to include mtime, size, path and type.  For an S3 system, it would be nice to be able to reference the md5 sum without transferring the file, (which I think the server will have already computed?).  This seems like the logical place to include it (though I wouldn't object to a more visible method too). 

 

 

(though type isn't clear to me, since it appears to be an integer)
