Changing letters between numbers

Hello,

since I have a stack of series on my HDD, I decided to keep them labeled like :
<series name> S01E01 <episode name>

Now I noticed that quite a lot of files have been saved under the form s01e01.
How do I get the s and the e upper case?

Thanks

Use the list replace method to replace s0 with S0, s1 with S1, e0 with E0, and e1 with E1.

Reply to #1: Use this regex to see if work.

REPLACE:
s(\d{2})e(\d{2})

REPLACE with:
S$1E$1
Use regular expresión

In this moment I am not in my computer so cant see if work.

EDIT: Change to S$1E$2
