[This is preliminary documentation and subject to change.]
In general, file names should appear in quotation marks. (The syntax does permit unquoted names, however, provided the names obey the identifier rules for the C programming language and allow periods except as the first character.)
The file name may specify a subdirectory. For example:
00:12:19:00 "Images/Pretty.gif";
Only forward slash (/) is supported. References to higher-level directories are not supported ("../Myfile.htm" is invalid.)
