Checking Your Available Storage Space in IONOS Web Hosting Packages (Linux)
Please Note
If the storage space limit of your package has been reached, you will no longer be able to upload files via FTP. You may receive the error message "451 Quota limit exceeded" in your FTP program.
If this occurs, please delete any unnecessary files from your webspace to free up space. If you do not want to delete anything, you can check your Package Change options and switch to a package with more webspace.
