Accessing the Windows file system from Ubuntu

Question

This is a screen shot of my 'Computer' screen.

Now, I'm trying to get a file from my Windows File system (I'm dual booting). A lot of places online said there would be a icon for the Windows partition. I've checked all the drives to no avail.

How would I get to it? I've seen other questions on here about it, but none of them are exactly like this one (i.e. none of them solve the problem for me (and in most cases, not even for the OP).

Answer 1

According to your screenshot, it is called "File System" (your windows partition doesn't have a label). Double-click on it and you should get to the root of your windows partition.

What about /host ? Ubuntu seems to be installed on your windows partition, using Wubi.
