Access EXT4 / EXT3 In Windows Using Ext2Fsd

Using Ext2Fsd, a filesystem driver for Windows XP / Vista / Windows 7, you can access your Linux EXT4 / EXT3 partitions easily as if they were native Windows partitions, straight from Windows explorer.

Ext2Fsd also supports writing on EXT4 or EXT3 partitions but the EXT4 write support is experimental and this FS driver will mount EXT4 filesystems in read-only mode, but you can change that if you really have to (but be careful when using this option as it may corrupt your data).

EXT4 partitions will show up as EXT3 in Windows explorer (at least that was the case for me – using Windows 7 and EXT4 partitions) but don’t worry, it will still work.

A lot more information about this (as well as some Ext2Fsd alternatives – see the comments), here: Mount EXT4, EXT3 Or EXT2 Partitions In Windows 7 Or XP
