The following driver provides ability to mount ext2/ext3 filesystems on Windows: http://www.fs-driver.org/

By default, Windows comes with a pitiful selection of supported file systems - FAT/exFAT and NTFS (and some CD/DVD/BD ones like UDF).
FAT is kinda old and kludgy - exFAT really just extends the size limitations of FAT.
Thus NTFS is really the only decent file system, however it's quite a bloated one with stuff like ACLs, legacy 8.3 filename support etc which I'd probably never use.
Basically had been looking for another filesystem which supports journaling which I can use to store stuff on.
The above ext3 driver looks nice.  Am just wondering how well it compares to NTFS in performance though, since it doesn't have the overheads of maintaining ACLs.

Anyone tried this yet?

(would also be nice if wee could have support for other filesystems on Windows >_>)
