           Summary: Exception using ftp when copying to a directory with a
                    tab in its name
           Product: Commons
           Version: Nightly Builds
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: VFS
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: seeraeuberkaeptn_fabian@yahoo.com


Hello, 

When I'm trying to copy a file from Windows XP Professional to a directory with
a tab in its name on a remote Sun Solaris Server I got an exception. It also
doesn't work if you try to copy the file from an Solaris server to another
Solaris server. The exception occurs not in the copy action itself, but when
checking the file size of the copied file on the remote server.

The exception is
org.apache.commons.vfs.FileSystemException: Could not determine the size of file
"ftp://myuser:mypassword@mySolarisServerIP/tmp/DeltaBuckets -
Americas/atlasfile.20050501".

It occurs in the following java program/snippet.
