I'm down to about 500mb on the hard drive, so I decided to buy an external hard drive to free up some space on my Mac. My question is, what's that best way to go about doing this? I want to delete files that I don't use very often from my mac (e.g. my photos) and store them solely on the external hard drive. Would it be OK to use Time Machine to do this? Once I delete them from my mac, won't that sync up with my external hard drive? Let me know if this needs more clarification. Thanks for any help!
