How to Split Large Files in Windows 11: 4 Simple Methods

In a world where digital communication is king, file size limitations can become your worst enemy. Sending a massive document via email? Trying to upload a video for a project? Fear not! Windows 11 offers several ways to split those behemoth files into manageable chunks. Let’s dive into the details, exploring various methods and tools you can use—all while keeping things fun and engaging.

Why Split Files?​

Before we jump into the how-tos, let's highlight why splitting files can be a lifesaver. Many email services impose attachment size limits (often around 25 MB), and large files tend to hang around like a bad smell when uploading. By breaking those files into smaller bits, you can easily manage and transfer them without a hitch. Plus, it gives you the satisfaction of hearing your computer whir in action.

Method 1: Using 7-Zip​

What You Need​

• 7-Zip: An open-source file archiver that’s easier than explaining "quantum computing" at a party.

Steps to Split Files​

• Download and Install: Head over to the 7-Zip website, download the installer, and set it up. Well done, you’re already closer to conquering file sizes!
• Open File Explorer: Hit Windows + E and find the large file you want to split.
• Right-Click that File: Navigate to Show More Options > 7-Zip > Add to Archive.
• Set Your Slicing Size: In the Add to Archive window, look for the Split to Volume, Bytes field. Type the maximum size for each chunk (for example, type 10M for 10 MB).
• Hit OK: Click OK, and let the magic happen! Your chunks will appear alongside the original file, numbered like they are in a fan-favorite TV show.

Recombining the Chunks​

When you need to piece them back together, just right-click the first chunk (001), choose Show More Options > 7-Zip > Extract Files, and choose your destination. Make sure all chunks are in the same folder to avoid a digital scavenger hunt!

Method 2: Using WinRAR​

WinRAR: The Classic Tool​

Much like a well-aged whiskey, WinRAR has stood the test of time. It’s a familiar utility for handling compressed files.

Steps to Split Files​

• Download and Install: Find WinRAR through a quick web search, download, and install it.
• Right-Click the Big File: Select WinRAR > Add to Archive.
• Configure the Size: In the Archive Name and Parameters window, enter your desired chunk size in the Split to Volume, Size field.
• Click OK: Just like that, WinRAR will work its magic, leaving you with neatly named files like part1, part2, etc.

Recombining in Style​

To bring them back into one, right-click part1, choose WinRAR > Extract Files, pick your destination, and let WinRAR weave its spell once more.

Method 3: Using PowerShell​

PowerShell: For the Command Line Enthusiast​

This method is like bringing a sword to a debate. It’s powerful and not for the faint-hearted.

Steps to Use PowerShell​

• Open PowerShell: Search for it using Windows + S and run the app.
• Navigate to Your Folder: Use the command cd PATH (replace PATH with your folder's address).
• Run the Split Command: Use this script (remember to replace placeholders):
  

  powershell
  $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)) {
  [CODE] $chunkFileName = "$($file)Chunk$i"
  [System.IO.File]::WriteAllBytes($chunkFileName, $buffer[0..($bytesRead - 1)])
  $i++

  }
  } finally {
  $fileStream.Close()
  }
  [/CODE]

Recombining Files​

For reassembly, use this script with your specific details:

$outputFile = "RecombinedFile.ext"
$chunkFiles = Get-ChildItem -Path "PATH" -Filter "MyFile.mp4*Chunk**" | Sort-Object Name
if (Test-Path $outputFile) { Remove-Item $outputFile }
$outputFileStream = [System.IO.File]::Create($outputFile)
try {
[CODE]foreach ($chunk in $chunkFiles) {
[CODE]$chunkData = [System.IO.File]::ReadAllBytes($chunk.FullName)

$outputFileStream.Write($chunkData, 0, $chunkData.Length)

}[/CODE]
} finally {
$outputFileStream.Close()
}[/CODE]

Method 4: Using Git Bash​

For the Tech-Savvy​

If you thrive in command-line environments, Git Bash can be your best friend.

Steps to Split with Git Bash​

• Install Git Bash: Download it from the official site.
• Open Your Folder: Right-click in your folder and choose Open Git Bash Here.
• Type the Split Command:
  

  bash
  split -b 10M MyFile.ext SplitFile_

Putting It All Back Together​

When you’re ready to unify those segments, use:

cat SplitFile_* > OriginalFile.ext
