I have a ASUS F3Kseries Laptop computer, running Window's Vista. I know I'm lame, just never have either the time or funds as of late to upgrade. Anyhow, I am now being prompted to free up space because my Data D: is just barely shy of being completely full.Unfortunately my basic computer skills are a bit rusty since owning a smart phone lol. The FIles are all backup files. So my main question is....Can I delete all of them or keep the most recent one? I just dont want to delete all of them and mess up my computer.Please let me know what I should do and thank you for your time.
