Dropbox? (Batch copy the files over each day - but dont just set the Dropbox folder at the super trend folder, it keeps trying to sync the file all day as data is written to it).
Email? (Have a batch job email them to the server each day).
rsync? (share the directly and rsync it once a day).
One comment I would like to make is unless you really really really really need the files at midnight, don't do anything to the files at midnight.... The reason is two fold.
First, PAC Display has to close and open each super trend file at midnight. If your batch file command is too fast, you might find some of the files in various states of roll over.
Secondly, a whole bunch of 'stuff' gets done by the computer and network at midnight. Its a really busy time for PC and network, if you can wait a moment, everything will go smoother and be less glitchy.
Sounds like you could easily wait till 1am or 3 am or better still 2:42am (or some other not on the hour time).
The files will still be there and they will be closed and ready to go.
Lets know what you end up doing, its a common issue with lots of solutions.
