Insert Character in Filename

[mtolleson]

My filenames all contain the string "to x", where x=a digit.

I want to insert a zero before the digit:

From: "to x"
To: "to xx", where the first x=0.

Noob here, and thanks.

With a checkmark inside for "v2", the "Match" and "Replace" can look like...
\b(to )(\d)(?!\d)/g
${1}0$2

It works beautifully, thanks.
