I have Bitcoin Core 0.13.1 (64-bit) and I can't get prune to work First I close Bitcoin Core...

The size of Bitcoin Core it is 105GB and I want to do pruning so I can have only 2 GB. I make a notepad file named bitcoin.conf and then I write inside prune=2000 or I even tried prune=&lt;2000&gt;.

Then, I have put this file at the install directory or I created the folder Bitcoin and I have put the notepad file in there at the path C:\Users\&lt;user name&gt;\AppData\Roaming\Bitcoin

After all these I open the Bitcoin Core, but nothing happens, it still is 105 GB.

What I am doing wrong? Please help me, I can't understand!
If you put startup commands on the command line, you need to add a dash in the beginning (e.g. bitcoind -prune=2000). 

However, when you put them in the bitcoin.conf, I think they have to be put without a dash (e.g. prune=2000). Yet, in the screenshot you show it has a dash. Have you tried putting it in the bitcoin.conf without the dash?
