OK, another small progress report on NextGen UCC...
I've run into a a snag with the Splitter script so I've decided to take a break and do a Practice project by re-creating the standalone UCC File Splitter and Merger program in AutoIT with Full GUI.
That side practice project is nearly complete and you can view some previews of the upcoming new version in the Splitter thread
HERE
Once that project is completed I'll be back to working on the NextGen UCC with a little better knowledge of what I'm doing.
