File Browser problem
 

When I create a level,I save it in "level" folder(:C/Programs Files/graal/levl)".When i go to file browser,I can only see the "level" folder and the folders that are in it but I can't see the level that I saved there...Why ?

You need to upload files through the File Browser. The files on your server aren't stored on your computer, but on an actual web server.

Drag your files from your computer into the levels folder on the server you're trying to upload levels for. Alternatively, you can right click in the levels folder on the File Browser and click "Upload file(s)" but dragging is easier in my opinion.
