BTIF Strengths

  • Allowed early digital archiving and web-based transmission of cleared bank checks
  • Encapsulated both image data and ASCII transaction metadata in a single file
Limitations
  • Completely proprietary and obsolete format
  • Lacks native support in modern operating systems and image viewers
  • Requires legacy plugins or specialized bio-format readers (like ImageC) to decode
FreeHand

FreeHand Strengths

  • Historically one of the most powerful and intuitive vector editors on the market, praised for multi-page support long before Adobe Illustrator implemented it
  • Files are generally compact and self-contained
Limitations
  • Completely abandoned proprietary format; Adobe actively blocked native import in modern versions of Illustrator
  • No support in modern web browsers; must be converted to SVG
  • Versioning fragmentation means parsers must account for wildly different binary structures depending on the specific .fhX extension used
