NOTE

This is a community-managed list of filetypes, and thus may be incomplete or inaccurate in some areas. Although ROOL do maintain a complete list of allocated file types, the list cannot be publicly released due to the confidential nature of some allocations.

For official information about filetype allocations, consult officially published documentation (e.g. the printed Programmer’s Reference Manuals books), or the ROOL-maintained FileTypes header in GitLab.
