Multi rename - protecting file extensions

[freenylon]

When using multi rename to do a Search/replace, a couple of times the dot before the file extension has been changed, rendering the file meaningless to the OS.

I know there is a tickbox (checkbox) for "Exclude extension", but it is deselected by default, which I believe is a dangerous and unwise default setting.

I would like the "Exclude Extension" option to be set to true by default.
It is the sensible thing to do.

I agree, perhaps it could be changed to "Include extension" and it should be disabled, so extension would be excluded by default.

Workaround - just click the option and press Esc, then open Multi rename again and it's saved.

This is getting serious. I just renamed a few thousand media files to remove the dot (.) within filenames.
I forgot to exclude the filename extension.

I just had to spend an hour manually reinstalling dots before the many different extensions of a few thousand files.

Please make the filename's dot extension protected during batch renames.

And, of course, today I discovered UNDO in the Command menu.

D'oh!

Yes, it is invaluable

But despite me using it for years now, every now and then I do forget to stop for a moment and see what is about to be done or how the items already just have been renamed, before closing the Multi Rename window (and thus loosing the access to the Undo option)

Thus there should be another fail-safe of some sort added
