A system and method in which a remote network source maintains source code and symbol files for debugging purposes with automatic downloading of the correct files when they are needed. Files are remotely maintained based on unique data associated with that file (unique parameters) that are independent of the product name, release and/or build number. Such data includes time / date stamp information and file size, or signature and age data. When a given file is needed, such as to debug an executable code module, a symbol server at the client constructs a path (e.g., URL) to the needed file based on the unique information from the corresponding executable file, whereby the correct symbol file is accessed. Via that symbol file, the correct source file may be located and accessed. Security via authentication and access control lists may control access to the files, and authentication may be automatic.
