2. Extracting Files:

Using 7-Zip via Command Line

7-Zip also provides a command-line interface, which can be useful for scripting and automation.

1. Compressing Files:

   • Replace archive_name.7z with your desired archive name and file1.txt file2.txt with the files you want to compress.

2. Extracting Files:

   • Use the following command to extract files from an archive:

     7z x archive_name.7z

   • Replace archive_name.7z with the name of your archive file.

3. Listing Archive Contents:

     7z l archive_name.7z

Examples

• Compressing a Folder:
