I realize this is a bit of late reply (OK, understatement
), but I wanted to let you know I tried your suggestion and it didn't work for me.
I just tried it again with the latest version of the 5.0 beta (build 3743) by going to Sites->Site Manager->[my website]->Transfer->Custom Skip List, and then adding "rx: (?
?!-min)[\w-]{4}|^[\w-]{1,3})\.js$" as the mask and "Name of File" under Compare.
That is what you were suggesting, correct?
