How to remove

[erikcelander]

Hmm, i downloaded bitcoin thingy to see how it looks etc and it started "synchronizing with network" and at the same time without me noticing it started to drain the space on my SSD, until i had 0 bytes left. it then popped up some bunch of shit that it was low and i was like wtf.. how do i remove and get back the (C:) space?
Sorry for noobish question

Deinstall it, go to C:\Users\your user name\AppData\Roaming\Bitcoin and delete everything. Make a backup of your wallet.dat before that if you have used it.

Next download Electrum or Mutibit from http://bitcoin.org/en/choose-your-wallet and not the BitcoinQT client. As Bitcoin.org states:

Bitcoin-Qt is the original Bitcoin client and it builds the backbone of the network. It offers the highest levels of security, privacy and stability. However it has fewer features and it takes a lot of space and memory.

It's still something weird.
I did as you said and when i checked i had some GB's left and now i checked again a couple of minutes later it's lesser, therefore it has changed without me doing anything..

Did you ever think that maybe something else if using space?  If you uninstalled the client and the datadir (path above) is empty then bitcoin is not using any space on your drive.

On a windows machine the only two places that the QT client writes to are:
C:\Users\your user name\AppData\Roaming\Bitcoin
C:\Program Files x86\Bitcoin

Didn't use the installer therefore no Bitcoin folder in x86

Goes without saying, but is the client closed?

c:\users\<your username>AppData\Roaming\Bitcoin\blocks

If that directory is full, make sure the client is still not running in your taskbar.

Removed the whole bitcoin folder.

As DeathAndTaxes said, there are only 2 bitcoin folders: the one where you had the client and the roaming/bitcoin one wich is automatically created by the client when you start it. Delete both and you removed everything.
