General questions

Where are my files stored?

The files you upload are hosted on our high-speed servers. Your individual virtual drive is set up for you when you register. By becoming a registered user you can create your own folders and upload files.
Why do I need to sign up?

Registration is free, easy, and takes seconds to complete. There’s no need to enter your credit card details.
What is 4s.io account verification?

Once you have signed up for a 4s.io account, you need to verify it prior to getting access to 4s.io services and features.
Why do I need to verify my 4s.io account?

Account verification confirms that the particular e-mail address, which you have entered while creating an account, is your actual e-mail address and ensures that you have access to it.

Only verified users can access their 4s.io accounts, share and download files and folders, preview files, leave comments to files, or use other essential features of the service.
How can I verify my account at 4s.io?

Upon the creation of your 4s.io account, you will receive an e-mail with a verification link. To confirm the verification of your account, you only need to click on this link.

Having clicked on the link, your web browser will open with a notification, that your 4s.io account has been verified.

In case nothing happens after you click on the verification link, you need to copy & paste it in your web browser.

Can I access my account with FTP?

4s.io Premium users can access their accounts via FTP (File Transfer Protocol).

FTP is a convenient way to upload, download and manage 4s.io hosted files. The advantage of this method is the absence of advertisements for everybody (whether the user has Premium membership, or not).

To access files with the browser quickly:
  1. Enter ftp.4s.io in the address bar of the browser and press Enter.
  2. Enter your 4s.io login and password in the required fields.

If the shared folder has a Read-only access, people can only download files from the folder, and not alter them in any way.

If you don’t want specific files from your shared folder to be visible to other people, you can set up the View only public files option and set the files in the folder as Private or Public.

Why does the Downloads counter give a different value for each file in Detailed Statistics, and it doesn’t coincide with the Downloads column value on the Main file panel?
