batch rename search and replace a pattern in a file name

i would like the batch rename to be able to handle regex like partials and find and eliminate or replace a string that is consistent like '_v4_Artboard 1xxxhdpi'

As Lumigraphics writes, it is all possible with a regex based string replacement, however it all depends on how loose or rigid you need the match to be… so more info is required.

In your example:

Nominee_1999_v4_Artboard 1xxxhdpi.png

Winner_2001_v4_Artboard 1xxxhdpi.png

Is it only and always the 3 characters in red that will vary (not 1 or 2 or 4 or more characters), with the bits in blue being static? Will the leading number 1 marked in green always be a number 1 or will this also need to vary by number or letter? And are the ‘xxx’ characters marked in red always going to be digits (numbers) or are they alphabetical characters or perhaps any character? For example, here are some subtle variations as examples:

Nominee_1999_v4_Artboard 1xxxhdpi.png

Nominee_1999_v4_Artboard 1xxhdpi.png

Nominee_1999_v4_Artboard 1xhdpi.png

Nominee_1999_v4_Artboard 1xxxxhdpi.png

Nominee_1999_v4_Artboard 2xxxhdpi.png

Nominee_1999_v4_Artboard Axxxhdpi.png

Nominee_1999_v4_Artboard 1234hdpi.png

Nominee_1999_v4_Artboard 2234hdpi.png

Nominee_1999_v4_Artboard 1A2Bhdpi.png

Exactly how “tight” (specific) or “loose” (flexible) do you need the regular expression to be (there are pros/cons either way)?

Batch Rename supports regular expressions. That's going to be your best bet.
