Can some one recommend me a good freeware file manager with the following options?
1. A preview pane to preview images, ascii files, ms office documents. This is a must for me.
2. Preview for pdf files is optional, but if present, it is definitely a plus.
3. Dual pane is optional
4. Customizing options. It should allow customizing the toolbar like adding new items to it, like calculator, notepad etc.
