Do the files that showed up in the scan frm TuneUp actually take up space ??
technically yes...and technically no
Physically the files are still on your computer..BUT they aren't counted as used space on the hard drive.
everyone assumes that when they press the delete key, your computer rushes out and wipes that part of your drive to get rid of the file
what REALLY happens when you press the delete key is that your computer "tombstones" the file...basically the way your computer accesses files (and knows how to access the files and where they are) is controlled by pointers...a pointer is a little bit of information that is appended to the file. this pointer is like an address telling the pc where the file is and what it belongs to...when a file is "tombstoned" the pointer is removed...when the PC finds a file without a pointer..it treats it as empty space and overwrites it with the new info
so physically the data is still there (which is how that undelete works..it looks for tombstoned files) but as you use your computer that data will get overwritten...so you don't actually have to worry about the files taking up space
any of that make sense?
