Is this a CMD.EXE window? It looks that way to me, so assuming it is and tab completion is not working you should right-click in window border at top and check the relevant option.
If you enable Fastedit, you can double-click on the name (which will then highlight) and put it on the clipboard by touching Enter. Later you paste by right-click.

on windows os you may type


in dos-box.

in regedit use 'edit' menu and choose search.

search for 'CompletionChar'

there are multiple hits:

for each occurrence double-click on 'CompletionChar'

it opens a dialog where you can enter 9 as dword value.

9 is the code for TAB character.

enter f3 to get next occurrence.

if you are not allowed to make a change, you need to restart with admin rights or ignore the message if it only for a few occurrences of CompletionChar.

On MS-DOS (not windows) there is no autocompletion as far as i know.



awesome thanks
