"IPSW" redirects here. For the component of XPwn, see ipsw.
See also: Disk Image Formats
IPSW (iPod[1] Software) files have the Magic Number 504B0304 (PK\003\004) and thus are ZIP archives. They can be modified with typical zip/unzip tools (i.e. change extension to .zip and double click). IPSWs are used to deliver the device's firmware to the end-user.
Archive Structure
- Restore Ramdisk
- Update Ramdisk (some firmwares don't have one due to various reasons)
- Filesystem (the largest .dmg file)
- Device Tree (model specific)
- Kernelcache (model specific; processor specific on pre-A4)
- BuildManifest.plist (first appeared in iPhone OS 3.0 beta 2)
- Restore.plist
- Firmware/
- all_flash/
- dfu/
- Baseband (may be one or many files depending on the model)
Example
Here are the contents of the iPhone 3GS 3.0 (7A341) firmware IPSW:

Notes
- IPSW files have been used since the very first iPod, though they have a different format than firmwares for iOS devices.
