How to Split Large Files in Windows 11

Managing large files can be cumbersome. Emailing them is often impossible due to size restrictions, and transferring them to flash drives or cloud storage can be slow and inconvenient. This guide demonstrates three methods to split large files in Windows 11 into smaller, more manageable chunks.

Method 1: Using WinRAR

WinRAR, a popular file compression utility, offers a straightforward solution.

Step 1: Download and install WinRAR from the official website. A system restart might be required.

Step 2: Locate the large file in File Explorer. (Example: a large video file exceeding 2.5GB)

Step 3: Right-click the file, hover over "WinRAR," and select "Add to archive."

Step 4: In the archive settings, find "Split to volumes, size." Enter the desired size (in MB) for each smaller file. (Example: 300MB for a 2.5GB file). Click "OK."

Step 5: WinRAR will create smaller files (e.g., "MyFile.Part1," "MyFile.Part2," etc.). To recombine, right-click the first part, hover over "WinRAR," and select "Extract files..."

Method 2: Using 7-Zip

7-Zip, a free and open-source alternative to WinRAR, provides similar functionality.

Step 1: Download and install 7-Zip from its official website.

Step 2: Locate the target file in File Explorer.

Step 3: Right-click, select "Show more options," then "7-Zip," and finally "Add to archive."

Step 4: In the "Split to volume, bytes" section, specify the desired size (e.g., "100M" for 100MB files). Adjust other settings as needed (password protection, etc.) and click "OK."

Method 3: Using PowerShell (Advanced Users)

PowerShell offers a command-line approach, suitable for experienced users.

Step 1: Search for "PowerShell," and run it as administrator.

Step 2: Navigate to the file's directory using the command cd PATH (replace PATH with the file's path).

Step 3: Execute the following PowerShell script, replacing "MyFile.ext" with the filename and "10MB" with the desired chunk size:

$file = "MyFile.ext"
$chunkSize = 10MB
$fileStream = [System.IO.File]::OpenRead($file)
try {
 $buffer = New-Object byte[] $chunkSize
 $i = 0
 while ($bytesRead = $fileStream.Read($buffer, 0, $buffer.Length)) {
  $chunkFileName = "$($file) Chunk_$i"
  [System.IO.File]::WriteAllBytes($chunkFileName, $buffer[0..($bytesRead - 1)])
  $i  
 }
} finally {
 $fileStream.Close()
}

Choose the method that best suits your comfort level and technical skills. Remember to always back up important files before attempting any file manipulation.
