qcow file type no. 1:
QEMU Copy-On-Write file

Application: QEMU
Description:
The QCOW image format is one of the disk image formats supported by the QEMU processor emulator. It is a representation of a fixed size block device in a file. Benefits it offers over using raw dump representation include:

Smaller file size, even on filesystems which don't support holes (i.e. sparse files)
Copy-on-write support, where the image only represents changes made to an underlying disk image
Snapshot support, where the image can contain multiple snapshots of the images history
Optional zlib based compression
Optional AES encryption
