No support for resuming interrupted transfers.

When a system or protocol lacks support for resuming interrupted transfers, it means that if a file transfer is interrupted for any reason (such as a network issue or user intervention), the process cannot be restarted from where it left off. Instead, the entire transfer must be initiated again from the beginning.

This can be particularly frustrating for users, especially when dealing with large files or slow network connections. Having the ability to resume interrupted transfers can save time and bandwidth, as well as reduce the likelihood of errors or corruption during the transfer process.

If you're experiencing this issue, here are a few steps you can take:

1. Check Protocol and Software: Ensure that the protocol and software you're using for the file transfer support resuming interrupted transfers. Not all protocols or applications have this feature.
2. Use Protocols that Support Resuming: Some protocols, like FTP (File Transfer Protocol), SFTP (Secure File Transfer Protocol), and HTTP with Range Requests, support resuming interrupted transfers. Make sure you're using a protocol that provides this functionality.
3. Check Server Configuration: If you're using a server for the file transfer, ensure that it's configured to allow resumed transfers. Some servers may have settings that control whether or not interrupted transfers can be resumed.
4. Verify Client Settings: Check the settings of your client software to ensure that it's configured to support resumed transfers. There may be an option or setting that needs to be enabled.
5. Split Large Files: If resuming transfers is not an option, consider breaking large files into smaller chunks before transferring them. This way, if a transfer is interrupted, you only need to restart the transfer of the specific chunk that was affected.
6. Consider Compression or Archiving: Compressing or archiving files before transferring them can help reduce the impact of having to restart a transfer. If a transfer is interrupted, you only need to re-transfer the compressed or archived file, rather than individual files.

If none of the above options are viable, you may need to explore alternative methods or tools for your file transfer needs. Keep in mind that choosing protocols and software that support resuming interrupted transfers can significantly improve the reliability and efficiency of your file transfers.
