The brush file extension is associated with Doodle, a paint program for the Xerox Dandelion computer related to the Xerox Star. Doodle was written around 1980 by Dan Silva, who later created Deluxe Paint, and Bill Bowman. This brush file type is marked obsolete and no longer supported. It is typically the case for old system files, discontinued software file types, or previous versions of documents and projects replaced by higher versions. Bitmap bi-level images like brush files consist of pixels as single bits, representing black or white. No known image viewers open brush files, but Netpbm converts them to portable bitmap images. Doodle brush files are simple images supported by Pbmplus/Netpbm, likely associated with the Xerox Doodle paint program. Files have a 16-byte header starting with 0x01 0x00. There is no software record for the .brush extension which is likely obsolete.
