File Formats

c-tree Plus (V7 and later) supports two different, but related, file formats:

• Standard file format - The default format for all versions of c-tree Plus.
• Extended file format - A format containing an extended header, which supports additional features, such as Huge and segmented file support. See “Extended Feature Support”.

The extended 8-byte file creation routines (e.g., CreateDataFileXtd8(), CreateIFileXtd8(), etc.) create Extended files by default. Extended files are not compatible with c-tree Plus V6. However, the extended 8-byte file creation functions will create Standard files when using the ctNO_XHDRS extended file mode. The existing file creation functions (e.g., CreateDataFile(), CreateIFileXtd(), etc.) create only Standard files.

The FairCom Drivers read both Standard and Extended files and create Standard files.
