How to Split Files using Winrar in Windows 11?

Split Large FIles in multiple Zip or Rar files using WinRar

Splitting a single large file is crucial when trying to upload and transfer it to someone. Most online platforms restrict the uploading of large files to save on their server bandwidth costs. While input bandwidth is often free, output bandwidth, especially for downloading large files, can be expensive. Many online file transfer websites limit single file uploads to less than 500MB. If you want to transfer a movie that is 4GB in size, it becomes impossible to do so via an online portal. To overcome this issue, you can use WinRAR to split your movie into multiple 400MB files and create final ZIP files. This way, you can upload all the ZIP files to the transfer portal without any problems.

Splitting files might be difficult or completely new to many users, so I have detailed steps and instructions to perform file splitting using WinRAR in Windows 11. Let’s get into the tutorial.

Installing WinRar Application:

  • Installing WinRAR is the first step in splitting large files.
  • You can download the latest version of WinRAR from their official website:

  • Then, you need to set the size in the “Split into volumes, size” option. By default, it is set to 5MB replace it with your own values. Currently, it supports Bytes (B), Kilobytes (KB), Megabytes (MB), and Gigabytes (GB).
  • I have set it to 1MB in the option, and finally, click the OK button to create the archive file.

Splitting Files using Winrar- Uses:

  • Large files can be tough to transfer over the internet or other media. Splitting them into smaller parts makes it easier to email, upload, or transfer them.
  • Many email services and online platforms have file size limits. By splitting files, I can bypass these limits by sending or uploading smaller, individual parts.
  • Downloading a large file can often run into errors and interruptions. Smaller split files are less likely to have issues, and if one part fails, I only need to re-download that part.
  • Splitting files helps me manage storage space on devices with limited capacity. I can store parts on different storage media or locations.
  • It’s also useful for creating backups and archives, especially if I need to fit them onto multiple CDs, DVDs, or other storage devices with limited capacity.
  • I can choose the size of each split part, giving me the flexibility to customize the file sizes based on my needs.


By using the above steps, I can easily split large files into smaller using WinRAR in Windows 11. This method not only helps in overcoming upload limits set by online platforms but also ensures smoother and more reliable file transfers. Whether I need to email, upload, or store these files, splitting them into smaller pieces makes the entire process hassle free. With the knowledge gained from this guide, I can confidently handle large files and transfer them without any barriers. Find more informative tutorials on our Homepage
