Appendix A: TWiki Filesystem

Annotated directory and file listings, for the 01-Dec-2001 TWiki production release.

Who and What is This Good For?

Interested Users and Site Administrators can find out in simple terms what each part of TWiki actually does. Adventurous Adminstrators with server access to files (eg: FTP) can also figure out where to look to make minor modifications, like changing hardcode text or color. Software Developers can get an at-a-glance overview of TWiki code architecture.

Directory Structure

You can rename the root TWiki directory - twiki - to whatever you like by changing it in the TWiki.cfg configuration file. However, to keep the current installation and future upgrades simple, you should leave the five main subdirectories intact:

Directory: Files: Used for:
twiki list Start-up info
twiki/bin list Perl scripts
twiki/lib list Configuration file, main library, Perl system modules, Plugins directory
twiki/pub list Public files (eg: images) and FileAttachments and their RCS histories
twiki/data list Individual topics (page content) and their RCS histories
twiki/templates list HTML templates, used by TWiki scripts
