What are ATPZ files and how to open them

Are you having problems opening an ATPZ file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your ATPZ files.

What is an ATPZ file?

An .ATPZ file is an Automise Project file.

Automise Compressed Project files store complete automation workflows created using Automise, a Windows tool by VSoft Technologies for automating tasks and processes. These project files include actions, schedules, conditional logic, variables, and other settings that define what Automise should do when a project runs. They are used whenever the project is saved in a compressed format, which is often the default for new projects.

Data inside these files is arranged as an XML document containing all workflow definitions. Because the file is compressed using standard ZIP compression, it reduces storage and enables easier sharing. Users or systems can decompress it with generic ZIP tools - renaming or adjusting the file extension may be needed for ZIP programs to recognise the format.

The file begins with the bytes corresponding to "PK" (the typical ZIP magic number), contains the ASCII string "project.fbp" located deeper (at offset 30), and includes an "ED" marker at offset 42. The string "PROJECT.FBP" is also embedded. These identifiers differentiate the compressed Automise project format from other ZIP-based files.
