PSB (Photoshop's Large Document Format) is an image file format supported by Adobe Photoshop CS and later versions of Photoshop. It is a companion format to PSD. PSB supports larger image sizes (up to 300,000×300,000 pixels), and increases various other limits.
PSB is structurally identical to PSD, except that the version number is 2 instead of 1, and some fields are larger (8 bytes instead of 4, or 4 bytes instead of 2).
[edit] Identification
PSB files begin with bytes '8' 'B' 'P' 'S' 0x00 0x02.
