> If a 'global' file is specified as a 'file' by one job - subsequent jobs cannot override
this source file to be an 'archive' (until the TT cleans up it's cache or a TT restart).
> The other way around as well -> 'archive' to 'file'
> In case of an accidental submission using the wrong type - some of the tasks for the
second job will end up seeing the source file as an archive, others as a file.
