From what you've said you are getting low on free space. I try to keep a minimum of 100 GB of free space to allow for optimum system and application performance.
The files that you have control over are located in the Documents, Downloads, Pictures, Music and Movies folders. You can use either of these two free apps, GrandPerspective or OmniDiscSweeper, to find the largest files on your drive so you can determine if they can be deleted or moved to an external HD for storage. I prefer GrandPrspective but try them both.
Note: you can also empty the Downloads folder after the apps and/or updates that were downloaded have been installed or applied. Many users have found a couple of Gigabytes of files in their Downloads folder which are no longer needed.
