Task 720: .TB2 File Format

Task 720: .TB2 File Format

After conducting extensive searches using web search tools and browsing relevant documentation, including Turbo C user and reference guides, I found that the .TB2 file extension is primarily associated with two obsolete formats:

  • A font file used by Borland Turbo C (an old C programming IDE from the 1980s-1990s), now considered unsupported and proprietary.
  • A backup file for TAS Books 2 accounting software (from TAS Software, later acquired by Sage), also proprietary.

However, no detailed file format specifications or binary structures are publicly available for either. Documentation mentions the extension but provides no descriptions of internal layout, headers, fields, or decoding details. Without specs, "properties intrinsic to the file format" cannot be determined beyond general file system metadata (e.g., size, timestamps), which are not specific to .TB2 and apply to any file.

Due to lack of specs, I cannot make a list of format-specific properties. General file system metadata includes: file name, path, size in bytes, creation timestamp, modification timestamp, access timestamp, permissions (read/write/execute), owner, group, and file type.

No direct download links for .TB2 files were found in searches. Results led to software archives (e.g., Turbo C installers on archive.org) or unrelated executables, but no isolated sample .TB2 files.

3-7. Without file format specifications, I cannot write code to decode, read, or write .TB2 files in any language, as that would require inventing a structure, which would be inaccurate and misleading. If you provide the specifications or a sample file, I can assist further.
