The format of most files created and used by Synchronet can be identified by the filename extension / suffix. This page is your guide to quickly identifying these files and links to format references, where available:
Each of the file formats listed here will have an identified encoding:
| Encoding | Description |
|---|---|
| Binary | You will need special software to view or modify files of this type1) |
| ASCII | Contains US-ASCII characters only: Any plain text editor should work, but note lines may be LF or CR/LF terminated |
| UTF-8 | Contains a combination of US-ASCII and UTF-8 characters with possible ANSI terminal escape sequences |
| ANSI | Contains a combination of US-ASCII and CP437 characters with possible ANSI terminal escape sequences |
| PETSCII | Contains CBM PETSCII characters and terminal control codes |
| SYNCASC | Contains US-ASCII characters with possible Ctrl-A codes |
| SYNCMSG | Contains US-ASCII and/or CP437 characters with possible Ctrl-A codes |
| SYNCDAT | Contains US-ASCII and/or CP437 characters with ASCII ETX (3/Ctrl-C) padded data records and/or fields |
Each file format has a reported support “status” from the developers:
