When I open the context menu (long-select) in an empty directory in the file browser, I see the following items:

Rename
Cut
Copy
Paste
Create Directory
Properties
Add to Shortcuts

None of these menu items, except for "Paste" and "Create Directory", makes sense when there are no files in the directory, and they all produce weird error messages, or no error at all:

Rename: shows the keyboard as usual but has "box" characters in the edit line. When I press the "accept" button (play button on Sansa e200), it displays "Rename failed"
Cut: no message
Copy: no message
Paste: works as usual
Create Directory: works as usual
Properties: shows the error message "File/Dir no found:" followed by a long list of "box" characters (like Rename)
Add to Shortcuts: error messages: "No parameter specified!" and "Plugin returned error"

I expected to see

a) fewer context menu items (only Create Directory and Paste) and/or
b) better error checking/recovery (plus better messages for the user)
