64 GB HD, 54 GB taken up by not my files

Hi everyone,

I have a 64 GB Macbook Air. I have been getting notices that I am running out of space repeatedly. It seems this is usual when your computer drops below 10 GB. However, I have run several scans of my hard drive and my files, which are basically all documents, are only taking up 10 GB

19 GB by "user", of which 11 GB are only actually my files

Library has 6.8 GB taken up, of Logs, caches, Application Support mostly

There is also another 5 GB folder labeled Library that is made up of updates, fonts, and dictionaries.

Private has another 4 GB

System another 4 GB

Applications 3 GB, mostly from word, adobe, and browsers

I am wondering, can I delete any of these other files, in Library, or Updates, or Fonts? I have read that deleting Caches and Logs aren't a good idea, but is there any other way that I can free up space here?

Please do not direct me to these random web links on how to free up space. I've deleted downloads and the trash and done all of the usual things. I am here as a last resort.

Thank you
