What is a WBK file?

WBK files mostly belong to Windows by Microsoft. A WBK file is the backup of a DOCX or DOC document created by Word. The file is automatically created by Word at given intervals in case there is a need to recover an unsaved document after Word or Windows unexpectedly shuts down. The WBK file can also be used to recover a corrupted DOC or DOCX document. Another type of WBK file is a workbook created by WordPerfect office productivity software suite. WBK is also the filename extension of the settings file of dock icons in a Windows 10 theme.

How do you open WBK files?

You need a suitable software like Windows to open a WBK 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 WBK file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WBK file directly in the browser:.

WBK file format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the WBK files looks like this:

The WBK file ending is mainly used by one program with a specific format. However, the following two file formats are common:

70% of all WBK files are based on the Microsoft Compound File format, which is also known as 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). Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE"). The app name of WBK files is Microsoft Office Word or Microsoft Word. There is also a globally unique identifier f4754c9b-64f5-4b40-8af4-679732ac0607 or 00020906-0000-0000-c000-000000000046. The file contains several sections which are named like 1Table, WordDocument, SummaryInformation, DocumentSummaryInformation, CompObj, Data and MsoDataStore. WBK files can be up to 160 MB in size, but are often around 30 KB - 7 MB. The file type was developed 10 years ago and is still in use today. A common filename is ~WRA0002.wbk or ~WRA0003.wbk. Such WBK files store data about backup, recovery, auto and save.
20% of all WBK files use ZIP compression, multiple files are compressed and combined into one WBK file. The 11 to 21 compressed files are called [Content_Types].xml, \_rels\.rels, \docProps\app.xml, \docProps\core.xml, \word\_rels\document.xml.rels, \word\document.xml, \word\endnotes.xml, \word\fontTable.xml, \word\footnotes.xml, \word\numbering.xml, \word\settings.xml, \word\styles.xml, \word\theme\theme1.xml and \word\webSettings.xml. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. The average file size is 31 KB with most files being between 12 KB and 460 KB in size. The keywords [Content_Types].xml are typical for these files. Files like these have the following tags: chapter, mankind, master, dungeonamker, skill and four.

The remaining 10% of all WBK files are different files with different signatures, such as Spiderman 2 sound/music data and DOCKS. They are often associated with streams, music, dock or backupof. If you want to find out what your WBK file contains, drag and drop it onto this page.
