Issue with name collisions

I am attempting to increment the number by 1 and it's giving me a name collision. I'm probably missing something super obvious here, but I've got an issue like as follows:

Filename | New filename
1.jpg | 2.jpg (marked red)
2.jpg | 3.jpg (marked red)
3.jpg | 4.jpg
4.png | 5.png
5.jpg | 6.jpg (marked red)
6.jpg | 7.jpg (marked red)
7.jpg | 8.jpg (marked red)
8.jpg | 9.jpg

I'm using renumber with number position 1, relative to existing number, number difference 1, zero padding automatic, apply to name and extension.

I've tried a bunch of different settings combinations to no avail, and am pretty stuck. I feel like it's something simple I'm missing, but it looks like it's doing them in the wrong order or something, for it to think that it would have name collisions. If they're renamed going from 8.jpg up to 1.jpg I'd think it would never have room for error, since there'd be no name overlap.

Thanks

Hi Connor,

Did you get an error message? When I ordered the files you described in ascending order (name collision set to ignore or fail) I got a message "File already exists".

Reversing the order (click once on Filename column header) removed the errors. Which is exactly what you described. :)

Best regards,
DF

Works now, I figured it was something simple like that, had no clue reversing filename order actually changed anything and assumed it was purely visual. Thank you!
