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

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):
  
  Code:

  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:
  
  Code:

  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

Conclusion​

Now that you've got the lowdown on splitting big files in Windows 11, you can send files like it's nobody's business. Choose your weapon—whether it’s the user-friendly 7-Zip, the classic WinRAR, the powerful PowerShell, or the command-line prowess of Git Bash—and conquer that file size limitation.
