How to write command file to delete all files except two...

[standish22]

OK, to make the issue simple, I have a folder C:\Test

In it I have
Test1.txt
Test2.txt
Test3.txt
Test4.txt

I want to right a quick command that will delete all but Test2.txt and
Test4.txt. I've tried the following and can't get it to work:

DEL /s /[!Test2.txt] /[!Test4.txt] *.txt

DEL /s *.sql /EXCLUDE:Test2.txt /EXCLUDE:Test4.txt

EXCEPT (Test1.txt Test4.txt) (DEL /s *.txt)

None of these work.

Can anyone help?

Thanks....

Possibly rename the files you want to save, delete what you don't want,
rename back to original?

OR

Does del test[13567890]*.txt work?
