[SOLVED] Any APP to edit name of MANY files? (adding some words at end of all files)

[SomeGuyonTHW]

Hi, imagine I have some files named:

ZZZ_ZZ.png
11111.png
BVBBB.png
DAS_DSAD.png
1238217300.png

(These aren't exact names just example to show: character length are different, Both words & numbers are used & there are some "_" there )
& they are about 1500 files!
I need to add
"_0"
at end of all of them so the results will be:
ZZZ_ZZ_0.png
11111_0.png
BVBBB_0.png
etc...
Any app that can do it? I just wanna add the same characters at the end of each file...
doing it manually will take me years, they aren't only 1500, it's only a part of it...
If anyone knows what this software is, I'll love them 99999999999999 & you saved me life.
