Like many people I discard unwanted material and delete it later using Secure Empty Trash. A quicker way is to copy-paste the name of the folder or file you want to delete across to a new folder created in another directory or part of the hard drive, so that when you drag it across and it asks whether you want to replace it you just click 'yes' and maybe 20GB of sludge vanishes almost immediately. Someone told me this might not be the best way to go about it, though he failed to explain why to my satisfaction even though I'm not especially well versed in computer matters. Can anyone advise me on this? Seems like a much better solution than waiting hours for the trash to empty. Thanks.
