Computer basics

How do I free up space on my computer without deleting something important?

The safest way to free space is to look at the storage categories first, then start with downloads, trash, duplicate installers, and large files you recognize.

The short answer

Check the storage screen, empty trash or recycle bin, review Downloads, remove unused apps, and avoid deleting system, library, or unknown folders.

Now try it on your device

Choose your path

Pick the device or situation that matches the screen in front of you.

Steps for Windows

2Review Temporary files and Downloads before deleting.
3Uninstall apps you recognize and no longer use.
4Empty Recycle Bin after checking what is inside.

One safety note

Do not delete System, Library, Windows, Program Files, or unknown folders.

Before you change settings

1Emptying trash only helps if files are already in trash.

2Downloads often contain old installers you can get again.

3Large videos and backups free more space than small documents.

What to know first

What this usually means

Downloads folder has old installers.
Videos or photos are stored locally.
Backups or sync folders are taking space.
Trash or Recycle Bin has not been emptied.

Do not do this yet

Do not delete System, Library, Windows, Program Files, or unknown folders.
Do not use a cleaner app unless you know and trust it.
Do not delete photos or documents before backup is confirmed.
