When 202 gb of ssd is running out, what happens to the laptop?

I bought a lenovo laptop last week, that had 202gb of ssd storage. It doesn't have any HDD storage. In a matter of 1 week i only have 60gb left. I didn't download much a 13gb file, 1.5gb file and skype. Why am i running out of GB so fast? And if i do, what happens? How can i get HDD storage?

You can get storage by deleting files or buying an HDD.

Plug in an external HDD but have a hunt around and see what's using the space.

Get WinDirStat and have it search your drive. It will show you where the data is.

If it is filling fast, you probably have an infection. Get and run Malwarebytes Antimalware if that is the case.

Try to clean up junk files with a tool like CCleaner:

If you have Win7 or 8.x, it may also be possible the Microsoft is downloading Win10 on your machine, using up lots of disk space…
