Files and directories
Files are the basic building blocks of your website. They are usually code or parts of code that make up a web application, as well as various media - images, videos, documents...
For a website to work properly, all of its components should ideally be on the same hosting. If you need to move files from your computer to the web host, upload them via FTP. This transfer is not limited by the size of the files, only by the speed of the connection.
Images and other media can also be uploaded via PHP, in which case the file size is limited to 128 MB for LowCost hosting, 256 MB for NoLimit and 512 MB for NoLimit Extra. Larger files can only be uploaded via FTP.
If you want to use a content management system such as WordPress, you can install it using the Application Installer.
Directory structure of Webhosting
Web hosting has a fixed basic directory structure. Make sure it contains the following directories at all times:
- session - session data file repository for PHP
- tmp - directory for various temporary files (important for uploading files)
- www - directory of the website itself
These directories can only be accessed by the user logged in with the main FTP account.
The following directories are part of the basic structure, but the site can function without them:
- www/domains - directory for creating separate content for aliases(more info about aliases)
- www/subdom - directory for creating subdomains(more info about subdomains)
For more information, see the article Webhosting - Restoring Basic FTP Structure.
File management via FTP
FTP, or File Transfer Protocol, is the basic method of transferring data between a user's computer and the web host. In order to use it, a computer needs an FTP client, a program that can communicate using the FTP protocol and includes an interface for moving files. We recommend using one of the following:
- WebFTP - FTP client in browser(interface ⧉ || instructions)
- FileZilla - multiplatform FTP client
Establishing an FTP connection
To connect your computer to the web host via FTP, you need the following information:
- FTP server address
- Username
- Password:
If you don't know your FTP credentials, please refer to the FTP Login article to find out.
More information about FTP accounts and their settings can be found in the article Webhosting - FTP accounts.
File upload via FTP
The specific process for uploading, editing and deleting files on a web host via FTP depends on the client you choose, and you can find the specific procedure in the client's manual.
Please observe the following precautions when working with files:
- Avoid deleting files that make up the directory structure of the web host.
- Make sure you are uploading the data to the correct folder: the web belongs in the www folder (or its subfolders).
- Be careful when deleting files directly on the web host - there is no recycle bin from which you can recover them later. If in doubt, get a backup.
Correcting file rights
It may be that files have rights set that do not allow the server to work with them effectively. Error 403 occurs. You can correct the file rights by following this procedure:
- Log in to the customer administration ⧉.
- From the top menu, select Hosting Services Webhosting.
- Select the desired service from the Web Hosting list.
- Select Tools from the left menu.
- In the Fix File Rights box, click Fix File Rights.

This fix will allow the server and users to access files that might otherwise be blocked.

Frequently Asked Questions
We accidentally deleted all the FTP content, can you restore it for us?
You must manually restore the web hosting directory structure according to these instructions. If you accidentally deleted the site files and do not have your own backup, you can request a (fee-based) restore of our backup.
