Prevent Duplicate Files Unzip

If you **don't want duplicate files or folders to be created on unzip**, here are some options:

—

### ✅ **Option 1: Overwrite existing files during unzip**
Most command-line tools allow overwriting without creating duplicates.

#### **Linux/macOS (using `unzip`):**

unzip -o my-archive.zip

> `-o` means "overwrite existing files without prompting".

#### **Windows (PowerShell 5+):**

Expand-Archive -Path "my-archive.zip" -DestinationPath "target-folder" -Force

> `-Force` tells it to overwrite without generating duplicates.

—

### ✅ **Option 2: Delete the target folder before unzip**
If you’re okay removing the old folder before unzipping:

rm -rf target-folder
unzip my-archive.zip -d target-folder

Or in PowerShell:

Remove-Item "target-folder" -Recurse -Force
Expand-Archive -Path "my-archive.zip" -DestinationPath "target-folder"

### ✅ **Option 3: Use a script to check for duplicates and skip them**

If you want to **skip existing files and not overwrite or duplicate**, you’ll need a script that does this manually — most GUI tools (like WinRAR, 7-Zip) prompt you for this action.

### ✅ **GUI ZIP Tools Tip (like 7-Zip or WinRAR)**

– If you're using **7-Zip**:
– It gives you the option: *“Overwrite”, “Skip”, or “Rename”* when duplicates are found.
– To prevent duplicates, always choose **“Overwrite”** or **“Skip”**, not **“Auto-Rename”**.

Let me know what system you're using (Windows, macOS, Linux), and whether you're using GUI or command-line, and I can tailor a precise solution.

tar -xvzf filename.tar.gz

### Breakdown:
– `x`: Extract
– `v`: Verbose (optional – shows progress)
– `z`: Filter through gzip
– `f`: Use archive file

### Example:

tar -xvzf my-archive.tar.gz

### Optional: Extract to specific directory

tar -xvzf my-archive.tar.gz -C /path/to/target-directory

Let me know if you want to **overwrite existing files**, **skip existing ones**, or do something custom during extraction.
