Flexible Hex Editor

Viewing and Editing OLE Compound Files

FlexHex is the only hex editor that recognizes and edits OLE compound files. A compound file is a small file system packaged into a single file, or a file-based implementation of OLE Structured Storage. Like a file system, a compound file contains a specific set of directories and files, which are called storages and streams.

Many software applications, most notably Microsoft Office, use compound files for storing data. The screenshot below shows a structure of a typical Microsoft Word .DOC file:

As you can see, the file contains a number of separate streams for storing the document data, its formatting information, summary and so on. An attempt to edit such a file as a raw binary file in an outdated hex editor will result in corrupted file structure and make the file unreadable. FlexHex, however, is up to the task of handling these files!

In addition to its powerful editing options, the Hex Editor offers the unlimited multilevel Undo/Redo feature, so you are never at risk of losing your data because of a typing error.
