The simplest way: right-click and send to compressed folder

Windows has a built-in zipper that does not require any extra software. Find the file or folder you want to compress, right-click it, and look for Send to in the menu that appears. Hover over Send to and you will see Compressed (zipped) folder as one of the options. Click that option.

Windows will create a new zipped file in the same location as your original, with the same name plus .zip at the end. If you zipped a file called Budget.xlsx, the compressed version becomes Budget.xlsx.zip. The original file stays where it was — zipping makes a copy, it does not replace anything.

This method works for single files, multiple files at once, or entire folders. To zip multiple files together, hold Ctrl and click each file you want, then right-click one of the selected files and choose Send to > Compressed (zipped) folder.

Key Takeaways

  • Right-click any file or folder, choose Send to > Compressed (zipped) folder, and Windows creates a zipped copy in the same location.
  • The original file or folder remains unchanged — zipping creates a new file with .zip added to the name.
  • You can zip multiple files at once by holding Ctrl, clicking each file, then right-clicking and choosing the compress option.
  • To rename the zipped file, right-click it and choose Rename, then type a new name without removing the .zip at the end.

Renaming the zipped file to something shorter

Windows automatically names the zipped file after the original, which can result in a long name if your original file had a long name. You can rename it to something shorter or more descriptive. Right-click the .zip file, click Rename, and type a new name. Keep the .zip at the end so Windows knows it is a zipped file.

For example, if you zipped a folder called Tax Documents 2024 Q1 January Through March, you could rename the zipped version to Tax Q1 2024.zip. The shorter name is easier to share and takes up less space in file listings.

Zipping a folder with many files inside

When you zip a folder, Windows compresses everything inside it — all the files and any subfolders. The folder structure stays the same when someone unzips it later. Right-click the folder, choose Send to > Compressed (zipped) folder, and Windows creates a .zip file containing the entire folder and its contents.

This is useful when you need to send a project folder to someone else, back up a set of related documents, or move a folder to cloud storage. The zipped version takes up less space than the original folder, so it uploads and downloads faster.

Checking how much space you saved

After you create a zipped file, you can see how much smaller it is than the original. Right-click the original file or folder, click Properties, and look at the Size line. Then right-click the .zip file, click Properties, and compare the two sizes.

Some files compress much more than others. Text documents, spreadsheets, and Word files often shrink to 20 to 50 percent of their original size. Photos and videos compress very little because they are already compressed by the camera or video software. A folder of photos might only shrink 5 to 10 percent when zipped.

Moving or deleting the original after zipping

Once you have created a zipped file and confirmed it contains what you need, you can delete the original to free up space. The zipped file is a separate copy, so deleting the original does not affect it. Right-click the original file or folder and click Delete.

Before you delete, open the zipped file once to make sure everything is there. Double-click the .zip file and Windows will show you a preview of what is inside. If something is missing, close the preview and keep the original until you figure out what went wrong.

Sending a zipped file to someone else

Zipped files are smaller and faster to send by email or file-sharing services. Attach the .zip file to an email the same way you would attach any other file — click the attachment button, find the zipped file, and select it. The recipient can unzip it by double-clicking the .zip file on their computer, whether they use Windows, Mac, or Linux.

If the zipped file is still too large for email, you can upload it to a cloud service like Google Drive, OneDrive, or Dropbox and send the recipient a link instead. This works better for files larger than 20 to 25 megabytes, which many email services will reject.

Frequently Asked Questions

Can I zip a file that is already a zip file?

Yes, but it usually does not save much space because the file is already compressed. You would end up with a .zip file inside another .zip file, which is rarely useful. Most people only zip files once.

What if I want to add more files to a zip after I create it?

You can drag files directly into an open zipped folder. Double-click the .zip file to open it, then drag new files into the window. Windows will add them to the zipped file automatically. This is faster than creating a new zip from scratch.

Does zipping a file make it password protected?

Windows' built-in zipper does not add passwords. If you need password protection, you can use third-party software like 7-Zip or WinRAR, which have password options. For most sharing, zipping alone is enough — password protection is only necessary if the file contains sensitive information.

Will the person I send the zip to need special software to open it?

No. Every version of Windows, Mac, and Linux can open .zip files without installing anything extra. The recipient just double-clicks the file and it opens automatically. This is why .zip is the most common compression format.
