Disk Drill recovered data
File type: Various data file
A cfb file extension identifies recovery data created by Disk Drill. A cfb file can contain data recovered during a scan.
These files are Disk Drill recovery artifacts rather than ordinary user documents.

The cfb file extension is used by Disk Drill, a data recovery application from CleverFiles for Apple macOS and Mac OS X.
Disk Drill creates cfb files during a Deep Scan when it cannot determine with certainty whether recovered data belongs to an XLS, DOC, PPT, or another Microsoft Office file.
The file therefore represents recovered data whose original file type could not be identified reliably. It belongs to Disk Drill's recovery process and is not a general-purpose document format.
Use Disk Drill on macOS or Mac OS X to work with data recovered as a cfb file. The file is a recovery artifact, so it may not open correctly in a document application.
If Disk Drill identifies or restores the original content, use the resulting file with the appropriate application rather than opening the cfb file directly.
There is no general-purpose conversion for the cfb recovery format. Disk Drill must first recover or identify the underlying data.
After recovery, the resulting file may be saved or exported in its identified original format, such as XLS, DOC, or PPT. Changing the file extension alone does not convert the data.
