PTB is an acronym for Power Tab File. Files that contain the .ptb file extension most commonly store music tablatures that are used in the creation of sheet music for stringed instruments such as the bass and guitar.
Many of the tablature files that contain the .ptb file suffix are created with the Power Tab Editor tablature authoring software.
The Peachtree Corporate Accounting software is also known to use the .ptb file suffix. When a PTB file is associated with the Peachtree software, the file contains backup data files that are used by the application to restore lost or corrupt data.
