What is a PB1 file

PB1 files mostly belong to Punch! Home Design Studio. PB1 files are design files used in architectural and CAD projects. They often carry floor plan data created with Punch! Home Design Studio and may also work as a dynamic library in PowerBuilder environments.
Key roles include:

Floor plan file: Contains layout details for building designs.

CAD file: Stores precise vector drawings for architectural work.

PlanSwift project file: Integrates project data with dynamic coding elements.

To open a PB1 file, use the software that created it. For example, you can get support via Punch! Home Design Studio or check for development tools at PowerBuilder.
FilExt.com tip: Few know that the same extension can hold both static design data and runtime dynamic libraries, reflecting older modular designs. Checking the file header may help identify the proper application.

PB1 file format details:

To find out what program is needed to open PB1 files, you need to determine the file format. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the PB1 files is as follows:

As a file extension, PB1 isn't very common and is used by a few programs, each with its own file format. The file formats most commonly found in PB1 files are:

• 35% of all PB1 files start with the bytes 3E 03 1E 00 crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The average file size is 28 KB with most files being between 14 KB and 53 KB in size. The file type is very old and rarely used today. Such files are related to plan and floor, and often include person-related information.
• 20% of all PB1 files start with the magic bytes B8 02 1E 00, which are always the first bytes of this file format. These files contain neither text nor words, but only data. The files are often between 7 KB and 21 KB in size. These files can be linked to school, and frequently comprise personal data.

All the rest of the PB1 files (45%) have different formats. Tagged as xmas, house, basement or kitchen. Drag & drop your file here to see the file format and a preview of your PB1 file!
