After some googling I found several ways to do the job:
- Explore2fs
- Pros: Open-source; No installing needed
- Cons: Read only; Exporting file is too slow...
- Ext2 IFS
- Pros: Mount EXT2/3 partition to a real disk letter; High accessing speed
- Cons: Installing needed; No source available
- Ext2Fsd
- Pros: Opensource; Mount EXT2/3 partition to a real disk letter
- Cons: Installing needed; Complex operations
- Diskinternal Linux Reader
- Pros: User-friendly interface with lots of whistles
- Cons: Installing needed; No source available; Not support UTF-8 charset
- Virtual Volumes
- Pros: Opensource
- Cons: Installing needed; Not completed yet...
Finally I chose Ext2 IFS 😃
