By default, an object file is read from and written to the same directory as its corresponding source file. But you can specify different directories for object files.
Specifying d:\obj in the Objfile Path text box of the Runtime Options dialog box tells Silk Test Classic to read and write all object files in the d:\obj directory, regardless of where the source files are located.
Specifying obj in the Objfile Path text box tells Silk Test Classic to read and write an object file in the directory obj that is a subdirectory of the directory containing the source file. In this scenario, each directory of source files will have a different directory of object files. For example, if a source file is in d:\src, its corresponding object file would be read from and written to d:\src\obj.
You can specify several directories in the Objfile Path text box. New files are written to the first directory specified. Silk Test Classic searches the directories in the order in which you have specified them to find existing files and will subsequently re-save existing files in the same directory where it found them.
