Do you have any file size or file type limits?
While we do not have any file size limits and you can upload any files with any extensions, we reserve the right to remove any single file larger than 1GB from the user account regardless of the content of the file with or without notice to the client. If you upload file using PHP (instead of FTP), max file size limit is 128 MB and it could not be increased anymore.
If your file is very large, it might be that web-based upload could fail, so we strongly suggest uploading big files with FTP client.
Also, if you do not want any file size based restrictions, you can always get a VPS package.
