Title: Find and Replace Script
Author: user
help me write a powershell script that will  loop through a folder, and for each *.dtsx file, to perform a list of find and replace commands for the content of the file, and then save it.

You can use the following PowerShell script to loop through a folder, find each `.dtsx` file, perform a set of find-and-replace operations on the file content, and save the changes.

Here's a breakdown of the script:

1. **Loop through the folder**: Use `Get-ChildItem` to find `.dtsx` files.
2. **Read the content**: Load the content of the file using `Get-Content`.
3. **Perform find and replace**: Use `-replace` to replace specific strings.
4. **Save the changes**: Use `Set-Content` to overwrite the file with the updated content.

### Example Script:

```powershell
# Define the folder path containing the DTSX files
$folderPath = "C:\path\to\your\folder"

# Define the find-and-replace pairs as a hashtable
$replaceMap = @{
    "OldString1" = "NewString1";
    "OldString2" = "NewString2";
    "OldConnectionString" = "NewConnectionString";
}

# Loop through each *.dtsx file in the folder
Get-ChildItem -Path $folderPath -Filter *.dtsx | ForEach-Object {
    $filePath = $_.FullName
    
    # Read the content of the file
    $fileContent = Get-Content -Path $filePath -Raw
    
    # Perform find-and-replace for each key-value pair in the replace map
    foreach ($find in $replaceMap.Keys) {
        $replace = $replaceMap[$find]
        $fileContent = $fileContent -replace $find, $replace
    }
    
    # Save the modified content back to the file
    Set-Content -Path $filePath -Value $fileContent
    Write-Host "Updated: $filePath"
}

Write-Host "All files updated successfully."
```

### Key points:
- **`$folderPath`**: Modify this to point to the folder containing your `.dtsx` files.
- **`$replaceMap`**: Contains the strings you want to find and replace in your files.
- **`-Raw`**: Ensures the entire file is read as a single string (needed for replacing content).
  
You can customize the `replaceMap` to match your specific find-and-replace requirements. Let me know if you need further modifications.
