Additional Help to Deal with Large Files

In addition to getting rid of large files, you can also do the following things to deal with your large files:

1. Move large files to a cloud drive

If your hard drive won't have enough space, why not transfer files to a cloud drive like OneDrive or DropBox. The free version of OneDrive only allows you to store up to 5GB worth of files, but you can always get a subscription to lift the limit to 1000GB.

2. Transfer large files to an external hard drive

It is also a nice choice to move large files to an external hard drive. If some programs are taking up too much space, you can also transfer the apps to an external hard drive.

3. Change the game location 

The Origin or Steam games could take up a lot of space. If your C drive is full, you can consider changing the game location to another drive. You don't need to redownload these games or buy them again.
