Splitting files for safer transfer

Brendan G · 2026-04-22

Risk of Data Breach: Why Splitting Files Matters

Large files pose a significant risk of data breach during transfer. When you send a massive file via email or cloud storage, it's vulnerable to interception and unauthorized access. Hackers can exploit vulnerabilities in file transfer protocols or steal sensitive information by intercepting unsecured file transfers. To mitigate this risk, splitting files into smaller, more manageable chunks is a viable solution.

When files are split, they can be transferred securely using various methods, such as encryption, secure protocols, or password-protected zip files. This approach reduces the risk of data breach and ensures that sensitive information remains protected. Furthermore, splitting files enables you to transfer them in parts, making it easier to manage and verify the integrity of each piece.

Best Practices for Splitting Files

To ensure safer file transfer, follow these best practices for splitting files:

  • Use a reliable file splitter tool: Choose a reputable tool that can split files accurately and securely. FileShot.io's file transfer platform provides a built-in file splitter that ensures seamless and secure transfers.
  • Select the right split size: Determine the optimal split size based on your file size, network speed, and transfer method. A general rule of thumb is to split files into 100-500 MB chunks, depending on your specific requirements.
  • Use encryption and secure protocols: When transferring split files, use encryption and secure protocols to protect data from interception and unauthorized access.
  • Verify file integrity: Use checksums or hash functions to verify the integrity of each split file and ensure that they are not tampered with during transfer.

It's essential to note that the split size and number of parts will depend on your specific file transfer needs. A larger split size may be necessary for large files, while a smaller split size may be more suitable for smaller files. Additionally, using a reliable file splitter tool can help you optimize your file transfer process and ensure that your files are transferred securely and efficiently.

Tools for Splitting Files

Several tools are available for splitting files, each with its unique features and benefits. Some popular options include:

  • FileShot.io's File Splitter: Our built-in file splitter is designed for seamless and secure file transfers. It allows you to split files into smaller chunks, encrypt them, and transfer them securely using our platform.
  • 7-Zip: A popular file archiver that also offers a built-in file splitter. It supports a wide range of compression algorithms and can split files into multiple parts.
  • HJSplit: A free and open-source file splitter that supports various file formats and can split files into multiple parts.
  • File Splitter: A dedicated file splitter tool that offers advanced features, such as encryption and secure protocols.

Secure File Transfer Methods

In addition to splitting files, using secure file transfer methods is essential for protecting sensitive data. Some popular options include:

  • SFTP (Secure File Transfer Protocol): A secure protocol that encrypts data in transit and provides secure authentication.
  • FTP over SSL/TLS: A secure variant of the File Transfer Protocol that encrypts data in transit and provides secure authentication.
  • HTTPS: A secure protocol that encrypts data in transit and provides secure authentication.
  • PGP (Pretty Good Privacy): A secure encryption method that encrypts data at rest and in transit.

When selecting a secure file transfer method, consider the level of security required for your file transfer needs. SFTP and FTP over SSL/TLS offer robust security features, while HTTPS provides a more basic level of security. PGP offers advanced encryption capabilities, but may require additional configuration and management.

Benefits of Splitting Files

Splitting files offers several benefits, including:

  • Improved security: By splitting files into smaller chunks, you can reduce the risk of data breach and ensure that sensitive information remains protected.
  • Increased transfer speed: Splitting files can help you transfer large files more efficiently, as each part can be transferred separately and in parallel.
  • Better file management: Splitting files enables you to manage and verify the integrity of each part, making it easier to track and maintain your files.
