What is a B01 file?

B01 files mostly belong to InPage.

The B01 file is a Split InPage Document that uses the Microsoft Compound file format. This file holds a part of a larger document created with InPage software and is used for desktop publishing and page layout tasks.
If you try to open it with a text editor, it may appear as unreadable binary data. You need InPage or compatible software to view and edit the file.

Key details provided by FilExt.com:

File Structure: It uses a structured compound format to store multiple streams.
Purpose: It splits a larger InPage document into smaller, manageable segments.
Usage: Essential for handling complex layouts in languages that require specialized typography.

How to open a B01 file

You need a suitable software like InPage to open a B01 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your B01 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a B01 file directly in the browser:. Just drag the file onto this browser window and drop it.

InPage
See the previous paragraphs to learn more about the main application. B01 files are often referred to as InPage page layouts because this type of file is primarily created or used by this software.
InPage
A *.B01 file is a part of a split archive created by the Microsoft Compound File Binary File Format. These files often contain parts of a larger document, such as an InPage document, that has been split into smaller segments for easier storage or transmission. The *.B01 file itself doesn't represent the whole document but rather a fragment. To access the complete content, it's necessary to combine all the split segments, including *.B02, *.B03, and so on, until the final *.Bxx file. Specific software is required to reconstruct the original document from these split parts. This file format is classified as Split Archive File.

B01 format details:

A file format defines how the data in the file is structured. 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. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our examination of the B01 files comes to the following conclusion:

B01 is rarely used as a file extension and predominantly uses a uniform format. The file formats most commonly found in B01 files are:

80% of all B01 files utilize the Microsoft Compound File format, which is also called Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. Compound document files work similarly to real file systems. They contain a number of independent data streams (like files in a file system) which are organized in a hierarchy of containers (like sub-directories in a file system). The first 8 bytes of the CFB format are D0CF11E0A1B11AE1 (which looks like "DOCFILE"). Sections and streams in the file are named DocumentInfo and InPage100. The files are on average 35 KB in size and range from 12 KB to 730 KB. The file type was created 10 years ago, but is still used today. Files like these are about urdu, paper, application and class, and have often person-related content.

All other B01 files (20%) have no uniform format. Drag & drop your file here to see the file format and a preview of your B01 file!
