Deleting root-node gives issues

[Anonym-Bruker]

When uploading a file with the command like this:
remarkable.php upload /path1/path2/path3/filename.txt
the script correctly creates all the directories path1->path2->path3 with the name inside path3. This worked excellent.

But then I tried to delete "path1" directly, without deleting the sub-directories.
This delete is not "recursive", so the sub-directories seem to still exist, and then seems to lead to some corruption.
When I tried to run the "remarkable.php list"-command, it gave an error message about wrong metadata (Don't remember the exact error message)

But if I deleted all the path2, path3 and the file inside path3, the list-command worked again, and it seems that I cleaned everything up.

Please consider one of two options:

1. Don't allow to delete directories that are not empty
2. Make the delete-command recursive to delete everything

Else, love the php-"app"!
