With Virtual Disk Driver you can mount a VMware virtual disk to your Windows hosts and use them as another disk drive attached to your system.

Virtual Disk Driver can open the following disk types for both read-only and read-write access:

- VMware 2.x Plain Disks (*.pln).
- VMware 2.x / 3.x Virtual Disks (*.dsk, *.vmdk).
- VMware 2.x / 3.x REDO log files based on both Plain Disks and Virtual Disks.
- VMware 2.x / 3.x differential / nested Virtual Disks (which actually are renamed REDO logs), based on both Plain Disks and Virtual Disks. There is no limitation on the nesting level.
- VMware 4.x Flat virtual disks (both split and monolithic).
- VMware 4.x Sparse virtual disks (both split and monolithic).
- VMware 4.x REDO log files (which actually are the same thing as split-sparse virtual disks) and differential / nested virtual disks (ditto).

Virtual Disk Driver allows you to use these types of virtual disks with minor errors, such as timestamp mismatch, sequence number mismatch, etc. (Virtual Disk Driver simply ignores those errors, it does not fix them.)

Virtual Disk Driver can also open the following types of virtual disks:

- Raw sector image which you can create with regular disk dump tools such as Linux dd command.
- Non-partitioned disk image, such as floppy image, removable disk image, and dd image of a single partition. (This is not actually a type of virtual disk, but rather how the virtual disk is formatted.)
- In this case, the whole image is treated as a single partition.

Virtual Disk Driver is also capable of creating REDO log files which VMware can use. This means that Virtual Disk Driver can open virtual disks in undoable mode, then you can commit the changes using VMware, or discard the changes by simply deleting created REDO log files.
