Are you trying to upload a large file (like a .zip backup or a video) using the File Manager in cPanel, only to have it fail or time out before completing? This is a common issue with a straightforward solution.
Understanding the Limitation
The "Upload" function in the cPanel File Manager is a web-based tool. This means it is running inside your browser and is subject to the same limitations as any other web page, including:
- Browser Timeouts: Your browser may time out the connection if it takes too long.
- Server Timeouts: To protect server resources from being overwhelmed, web servers have hard-coded limits on how long an upload can run and how large a file can be (e.g.,
upload_max_filesize).
This tool is excellent for managing and uploading individual files or small .zip archives, but it was not designed for transferring massive, multi-gigabyte files.
The Solution: Use a Dedicated FTP Client
To avoid these browser and server timeouts, you should use a dedicated FTP Client (File Transfer Protocol client). This is a piece of software designed specifically for the purpose of reliably transferring files to and from a server.
We recommend a free, open-source programme like FileZilla. An FTP client creates a much more stable and reliable connection, and it is not subject to the same timeouts as a web browser.
What To Do Next
Once you have an FTP client installed, the transfer process is much more robust. We have a complete guide that explains how to use an FTP client for large files, including tips on resuming failed transfers and splitting files for maximum reliability.
