If you are in need of an easy way of uploading and editing files on your webserver – also when SSH/FTP or other normal means of doing this should not be available, I recommend installing this great little script called File Thingie. It will enable you to upload and manage (rename, delete, ..) your files, without letting evil-doers (that may know your password) getting out of the upload root. It is one single file to download – that’s all. Check it out!
