How To Upload Files
There are two ways to upload files to your server. One is via the File Manager, the other is via SFTP. Here we'll cover the file manager. For SFTP please see the SFTP page.
File Manager
You can upload filed to the File Manager if they are in a Zipped Archive and under 1GB Big, if you have mods, a world file, or something like a file you wish to upload.
1 You can drag and drop the Zipped Folder or File inside of the File Manager. You can view the percentage of the upload if you click on the "File Uploading" button.

2 You can click the "Upload" button, this will bring up the Explorer on your Local device. You can find the File you wish to upload that way. You can still track it's progress by clicking the "File Uploading" button.

Common Mistakes
File Size - Make sure your folder is under 1024mb, or 1GB Big. You can check the file size by right clicking on the file & going to properties, to see it's size.
File Type Not Supported - At the moment, you can not upload normal folders directly into the File Manager, if you want to do this without zipping up the folder, you will need to use SFTP
