To zip a file in Windows 7, download and install a file archiver utility, such as 7-Zip, and use its file compression function to create a zip archive. Once you initiate the zipping process, modify the archiving parameters, add a password if necessary, and click OK to complete the process.
- Download and install 7-Zip
Use your Web browser to navigate to the 7-Zip home page, and click on the Download link for the latest version. Make sure to select the version that corresponds to your operating system: x86 for a 32-bit Windows 7 and x64 for a 64-bit OS version. Once the download is complete, double-click on the executable file, and follow the installation wizard instructions to complete the process.
- Initiate the zipping process
Click on the Start button, and select All Programs. Click on the 7-Zip folder, and select the 7-Zip File Manager option. Use the main 7-Zip window to navigate to the file you wish to zip, and click on it. Click on the Add button in the top left corner to initiate the process.
- Modify the parameters
In the Add to Archive dialog box, type in the name of the archive, and select the desired compression format. Modify the level of compression by selecting one of the six options from the drop-down menu next to the Compression Level parameter. In the encryption section, type in the password if you wish to protect the zipped file, and click OK to finalize the process.
