I have installed Cygwin software which contains C++ and c compiler, debugger and some more things. Later on I decided to install all what Cygwin contains in itself. But I run out of memory on C: disk. So I stopped installation or extraction. Anyway, Whatever was left on my C: disk it takes its space. I want to remove it.

How can I delete those data remnants from HDD?

I tried CCleaner and C: disk cleaner, but it did not help.

Have you checked the recycle bin? – ott-- Nov 19 '11 at 20:48
No, they are not there. – ucas Nov 19 '11 at 21:26

Assuming you installed cygwin into c:\cygwin simply delete this folder with all it's content.

But please be aware you also delete you cygwin-users' home directories then. So if you created something under c:\cygwin\home\ you might backup this data prior to deleting.
