Depending on what operating system you have Skinny, you should Scandisk and defrag regularly.
To clear out any shite you can get programs freeware such as CCleaner, that clear out your rubbish to free up space and increase speed.
There is another program called Easycleaner.
If you keep a lot of photos, videos, music or even loaded programs you dont use anymore....have a clear out.
But always be careful you know what you are throwing out.....it could be disastrous.
