QEMU Copy-On-Write data

A qcow file extension is related to the QEMU Copy-On-Write file format used to store disk images.

Further details:

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

What is the meaning of a file extension?

File extensions are characters that appear after the dot in a computer file's name. For example, the file "unknown-file.qcow" has the file extension "qcow". This is used to identify which program should open the file or what file type it is.
File extensions help you organize and manage files. They provide a quick and easy way to identify and associate the file type with the appropriate software.
