How to find out what's taking up space on a C drive in windows 11?

Let's talk about the Disable Hibernation - that's another popular method to free up space and find out  what's taking up space on your C drive. Disabling hibernation can temporarily increase the available space on your C drive, and it's a good way to identify which files are occupying the most space.

To use the "Hibernation" trick to free up space on a C drive, follow these steps:

1. Press the Windows key + X to open the Quick Link menu, and select "Control Panel."

2. In the Control Panel, click on "System and Security."

3. Click on "Power Options."

4. Click on "Choose what the power buttons do" on the left side.

5. Click on the "Change settings that are currently unavailable" link.

6. Uncheck the box next to "Enable hibernation" and click "Save changes."

By disabling hibernation, you'll be able to use the free space to run a disk cleanup or a disk usage analysis tool to find out what's taking up space on a C drive. This can help you identify and delete large files or programs that are no longer needed, freeing up space on your hard drive.

Keep in mind that disabling hibernation will also disable the ability to hibernate your laptop, so if you want to be able to hibernate your laptop, you can re-enable hibernation after you've finished identifying the space-hogging files.
