Open your service and choose Files. You are looking at your webspace.
- Upload - press it, or simply drag files from your computer onto the page ("Drop here"). Progress is shown per file.
- New File / New Folder - create either, name it in the box that opens.
- Click a folder to enter it; the path above the listing walks you back up.
- Each file's row offers: Edit (opens text files in a browser editor - save writes straight back), Rename, Download, Permissions (the Unix mode, e.g. 644 for files, 755 for folders), and Delete, which asks before it acts.
- Archives: upload a .zip of your whole site and extract it on the server - far faster than uploading a thousand small files.
The listing shows each item's size and when it was last modified. If a page of your site behaves oddly after an edit, this Modified column tells you what changed last.
