I have files:
1.stl
2.stl
3.stl
4.stl
5.stl
6.stl
...
I need:
1_1.stl
2_2.stl
3_3.stl
4_4.stl
5_1.stl
6_2.stl
7_3.stl
8_4.stl
...
Basically, I need a way to get the autonumbering to reset after incrementing to 4.
I don't have any other variable in the file name, or in our file creation process that I can use as a condition. Just need the first 4, then reset the numbering.
Maybe there is some kind of auto-sorting method I could use, where every 2nd file is sorted to x folder, every third file is sorted to y folder, etc..
I'm stuck, any help would be greatly appreciated, and thank you in advance!!
