Large uploads can be limited by the transfer method, available storage, PHP settings, application limits or connection stability.
Applies to: Website uploads through File Manager, FTPS or a web application
Choose the transfer method
| Method | Use for |
|---|---|
| FTPS | Large website files, archives and repeated transfers. |
| SiteWorx File Manager | Smaller manual uploads and extracting an archive on the server. |
| Application upload screen | Content that must be processed by the application, within its own and PHP limits. |
Work through the checks
- Check the hosting account has enough storage and inodes for both the uploaded archive and extracted files.
- For FTPS, use explicit TLS on port
21and passive mode. - For a web application, check its upload limit and the relevant PHP values such as
upload_max_filesize,post_max_sizeand execution time. - Upload a smaller test file to confirm the path and permissions.
- Avoid repeatedly restarting a failing multi-gigabyte upload without checking the error and remaining quota.
- Verify the final file size or checksum before deleting the source copy.
