1. Invoke-WebRequest
Advantages:
- Built into PowerShell, no need for additional libraries.
- Easy to use and straightforward for simple tasks.
Disadvantages:
- Can be slower for large files.
- Limited options for error handling and resuming downloads.
Estimated Time (1 Go ):
- Could take between 10 to 30 minutes or more, depending on network speed, latency, and system resources.

Error details: $_.Exception.Message" }} |
2. System.Net.WebClient
Advantages:
- Faster than
Invoke-WebRequestfor moderate-sized files. - More options for error handling due to .NET framework capabilities.
Disadvantages:
- Requires object instantiation, which could be considered overhead for a single download operation.
Estimated Time (1 Go ):
- Approximately 5 to 15 minutes, depending on various factors like network speed and system performance.

Error details: $_.Exception.Message" }} |
3. BitsTransfer
Advantages:
- Optimized for large files and background transfers.
- Can resume interrupted downloads.
- Built into Windows, making it reliable for Windows environments.
Disadvantages:
- Limited to Windows systems.
- Less flexibility for error handling compared to WebClient.
Estimated Time (1 Go ):
- Approximately 5 to 20 minutes. BitsTransfer is designed to be more reliable over long periods and can resume interrupted downloads, making it suitable for large files.
