Lower case file names with no spaces

[yovation]

Hello,
How would I do a rename batch conversion to remove the spaces in a file name and make all characters lower case.

Thank you.

I think that is a bit beyond the capabilities of IrfanView. You should go for a dedicated file renamer program that is way more up to the task for things like that.

Here's a few:
