I am currently in Windows and was wondering if there is any way I could mount my Linux partition, so I can access and transfer files? The file system is ext4
You need a driver to mount an ext2 partition, like this one (not sure if this one will work on Win 7, it isn't specified, if that is important).
EDIT: to reflect slhck's comment, this will only work if you are using ext2fs/ext3fs, I can update with other options if this is not what you are using.
EDIT2: This one will work on Ext2,3,4 (0.50 and up for ext4) and will run on all modern Windows versions
