When we have dual booting in our computer, with the combination of ubuntu and windows 7 then accessing the files in the linux partition becomes possible with the Ext2Read tool. There are very less number of tools that allows you to access the ext4 partition from windows partition like NTFS. You can access, copy and manipulate with the files without boundaries hereafter, even you booted windows operating system.
Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents.
It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file.
