The app on Old Toad's site for batch rename with capture date/time
Doesn't work. In fact, if you try to download it, the ZIP unzips as the Change Title to Specific Date, which is a different thing altogether, obviously. I don't know how to contact Old Toad to point this out, and I may have somehow misunderstood the situation, though the instructions offered for the app specifically say that the app will rename all files to the date you insert for the first file.
I want to rename all files with their individual capture date and time, thus: 2018-12-21_183314
Any help? (And thanks to OT in advance for having converted these scripts by Leonie to apps!
