What is a C01 file

C01 files mostly belong to MYOB AccountRight. C01 files are used as proprietary data containers by specific business and archive applications.
  • Tax Reports: In Australia, MYOB AccountRight uses C01 files to store the Taxable Payments Annual Report. This file holds internal tax data in a format meant for controlled processing.
  • Postcode Data: In the UK, some C01 files contain address information, such as postcode data (often noted as an AddressBase data file) used by AutoRoute Express.
  • Compressed Archives: Other C01 files serve as one segment in a series for compressed data. Here, each file is part of a multi‐segment archive that must be reassembled, often with a tool like the C01 Converter.
  • FilExt.com notes: These files are not typically opened with a text editor. Instead, they require the specific application that created them. For more details on the Australian tax report format, please visit MYOB AccountRight.

    How to open C01 files
