Question

Batch Rename using Regular Expression

My stupid phone sometimes names photos 20200226_150253.jpg and then other times names them 2020-02-27 178241.jpg. I swear I haven't mess with any photo settings on my phone. So, when  I upload images to a single 2020 Photo folder, the images don't arrange in chronological order.

Can someone provide me with a Regular Expression to select 20200226_  --selecting all XX(month) and all XX(day) and replace with the same MM/DD, in the format 2020-02-27  --so that I can fix all of them in one single batch rename? 

Thanks so much!

First regex (original filename):

 

Find:

[-| |_]

 

Replace:

(blank, nothing)

 

Second regex (intermediate filename):

 

Find:

(\d{8})(\d+)

 

Replace:

$1-$2

 

 

The result:

Hmmm, I'm not sure if I read/understood the request correctly the first time!

 

Second regex (intermediate filename):

 

Find:

(\d{4})(\d{2})(\d{2})(\d{6})

 

or

 

(\d{4})(\d{2})(\d{2})(\d+)

 

Replace:

$1-$2-$3_$4

 

Final result:
