Error message when double click on the root drive c:

[rotong]

Error: The synthaxis of the filename, foldername or volumename is wrong.
Did a reindex of the harddrive but without result.
Not possible to open explorer when you doubleclick on the root drive C:
However, it is possible to open explorer if you right-click on the root drive C:

[NotNull]

- Go to Menu => Tool => Options => General => Context Menu
- In the right pane, select context menu item Open (Folders)
- Set its Command to

$exec("%1")

- OK

If C:\ still does not open on double-click:
Set the Open (Folders) command to

$exec(explorer.exe "%1")

It works!
Thank you very much.
Cheers!
