Folder structure

After you connect, there will be some folders created there for you. Do not rename or delete them, because new ones will be created again. Please use these folders to keep your content well structured.

  • _backups* - If not using github, use this to upload assets and zip sources.
  • share* - For sharing files with your team.
  • html5* - For hosting JS games (static files only).
  • flash* - For Flash games.
  • unity* - For Unity WebGl games.
  • unity_webplayer* - Was for Unity WebPlayer games

Create folders inside the above folder for each individual game even if it’s only one game.

Linking uploaded files

After uploading a game, first test if it works using hostname, only then try link, because the latter will be cached.

For example, if your directory is spajus, and you have uploaded a Unity WebGL game into unity/Sumo01/ SFTP folder, following link should open your game:


To link the game in production, remove the -direct part from link:


It is very important to remove -direct in production links. Games that will ignore this rule will get blocked due to exceeding storage server traffic limits.


If you have trouble connecting to your account:

  • Make sure port is set correctly (211). Common mistake is to try with port 221 instead.
  • If you are using older version of WinSCP, try updating to latest.
  • If you have tried too many times, your IP may have been blocked. Take a 20 minute break and try later, after double checking login details.

If you see an error page when trying to open a game, make sure that:

  • URLs are case sensitive, make sure your uploaded files and folders are linked with exactly the same case as they are named.
  • Make sure that permissions for uploaded files are rw-rw-r– (or 664) and for uploaded folders: rwxrwxr-x (or 775).
  • Add /index.html to the end of your url if you see error 500.

CDN cache

Content that is hosted is cached using a CDN for fast deliverly.

If you need to change files that are cached, just rename your game folder and update the links.

Using an intermidary iframe will allow you to do this without breaking any upstream sites that correctly linked to the game.

upstream site > game index iframe > gamev1.0.0

Resetting forgotten password

As Y8 Storage uses a seperate password, if you need to change it, visit

After changing password, please wait 15 minutes before trying to use it, or you can get blocked for too many bad password attempts. It takes some time for server to apply the changed password.

Submitting game source code or backing up files

Put zipped files into the _backups folder. Don’t worry if they disappear from the folder. This is expected behavior for archiving in the cloud.
