I have about 3000 numbered images (0001.jpg, 0002.jpg etc). I want to delete half of them, but evenly spread-out: i.e. every other file (not sequentially). Is there a way to select odd/even-numbered files?

This would select all the files whose name ends in an even number followed by `.jpg`, and deselect everything else:

```plaintext
Select *[02468].jpg TYPE=files DESELECTNOMATCH DESELECTOTHERTYPE

```

(If it's a one-off, you can also do similar in the UI via Edit \> Select By Pattern and use the same wildcard `*[02468].jpg`.)

Thanks, I'll try it.
