Hi, I'm trying to replace spaces with dots within the parentheses in a large list of files.

Files:

Microsoft Minesweeper 03 05 (2020 04 16) 10 p. m.jpg
unnamed - (2022 04 10) T004157.232.jpg
etc...

Goal:

Microsoft Minesweeper 03 05 (2020.04.16) 10 p. m.jpg
unnamed - (2022.04.10) T004157.232.jpg

I was trying Lookahead (regex):
Search: \ (=?(\(\d{4}))
Replace: . <= dot

I also tried to create groups with the spaces but it didn't work either:
Search: \d{4}(\ )\d{2}(\ )\d{2}
Replace: \.\.

I'll apreciate any help.
Thanks.

Replace: .*\K(\d{4}) (\d{2}) (\d{2})
with: \1.\2.\3
Use regular expressions

Better...

Replace: \s+(?=[^(\)]*\))
with: .
