How to Perform File Compression on Windows

Windows has built-in support for file compression. This makes it easy to reduce file sizes and share files more efficiently.

Using Native ZIP Compression

Windows supports the ZIP format without needing extra software. Here is how to create a ZIP file:

1. Select the files or folders you want to compress.
2. Right-click the selection, go to “Send to,” and choose “Compressed (zipped) folder.”
3. A new ZIP file appears in the same location, containing the compressed contents.

This method works well for quickly reducing file sizes for email attachments or archiving.

Utilizing 7-Zip for Advanced Compression

For more compression options, 7-Zip is a useful tool. It is free and open-source, and it supports formats like 7z and TAR. Here are the steps to compress files using 7-Zip:

1. Download and install 7-Zip from the official website.
2. Right-click the file or folder you want to compress.
3. Select “7-Zip” from the menu, then choose “Add to archive.”
4. Set your preferred options (e.g., format, compression level), then click “OK.”

7-Zip gives you more control over compression settings than the built-in Windows tool.

Mounting ISO Files

Windows also supports mounting ISO files. ISO files are optical disc image files often used for software distribution or backups. Mounting an ISO file makes it available as a virtual drive. To mount an ISO:

1. Locate the ISO file using File Explorer.
2. Right-click the file and select “Mount.”
3. Open “This PC” to find and view the mounted drive.
