Yes you can. It will actually make your PC run faster.
Assuming you mean your browser's cache, then you can certainly delete (or clean) it without hurting anything. However, the browser cache is there to speed up the displaying of pages, so after you clean is out, your browser will render pages slower for a while, until it fills the cache back up with your commonly-used items. Browser caches are also the place where things like automatic login cookies are stored, so by deleting your browser cache, you will be prompted for a password the next time you try to access any password-protected web site.
Caches in general work this way: they are a place to temporarily put things which are commonly needed. Thus, a cache can be cleaned out or deleted without impacting the functionality of your computer - that is, they perform no ESSENTIAL function. However, they provide a (significant) performance increase, as a getting things from a local cache is always faster than getting from the original location.
If you are referring to cache memory (frequently mentioned in the specifications of a CPU chip), this cache is part of the CPU hardware itself, and cannot be turned off or deleted.
you can't
Yes you can.
No, the pcm will detect the loss of the cat and performance will suffer. Plus it is illegal.
A person who saves anything and doesn't delete anything or do any computer clean ups.
no if you delete something on Google you delete everything.
No you need to use itunes for that
In your iTunes library, just uncheck anything that you don't want to transfer to your iPod when you sync it. The check box should be on the very left of the row when the song is highlighted.
If it is in an e-mail, you can just delete the email without opening the virus attachment. Otherwise, I don't know if it's possible!
you can't. wouldn't that be nice tho....
No possible way
Anything you delete in disk cleanup is a temporary file and non essential to your computer.
Never delete anything from the WINDOWS folder in 'my computer'. This folder holds everything important that the computer need to run such as program files. The most important folder in WINDOWS is "System 32", never delete it.
