Topfield 5800/Troubleshooting/USB invalid char

The Toppy can name recording files using characters that are not allowed on a Windows PC. Any one of these is likely to cause problems: \ / : * ? " < > | Simplistic tools like Altair may fail to retrieve such files, but often this failure won't occur until the whole contents of the file have been transferred, making it a particularly annoying problem. If you get one of the following types of error then check the filename for the above characters:
 * A 0 byte file following an apparently successful transfer.
 * "Cannot copy the selected file. Already used in the other process or unknown error occurred" (in a standard Windows error box).

The solution is to either use a better tool (like TopSet or an FTP setup), or rename the file on the Toppy before transferring it:


 * 1) Select the recording in native Archive
 * 2) Press the Blue button to select "Options"
 * 3) Select "Rename"
 * 4) Press Up to select the filename part
 * 5) Press Right repeatedly until the first "bad" character is highlighted
 * 6) Press Red to delete that character
 * 7) Repeat from 5 if necessary.

0 Byte files have also been reported associated with faulty USB cables and paticularly active USB extenders here
