Thanks a lot for your quick reply.

thanks and yes I am doing that.

So, how will it find the files if I use direct? would not the filename have the "/"
chopped off and therefore point to the wrong location?
(which is the last error message I have seen before I gave up and moved to using
strings and not files, but that approach prevents me from using any form of staging
without some complex machinery)
I could conceivably use a relative path (not sure whether it works since it will go upwards, but I can try).
Can I define a path relative to SWIFT_USERHOME or USER_HOME in swift?
