text editor with replace for all files in a folder

[maps4gps]

Is there a free (easy to use) text editor which will work on all files in a folder without manually opening each file individually?  I have 150 .mp files which need two items changed and the results from a google search are wasting time with version which do not actually do this.  Thanks.

Macromedia/Abobe Dreamweaver will do it.

But, Notepad++ will also do it and its free.  Go to Search>Find in Files
