Edit multiple external weblinks in Power Point

[macareno]

Hi Guys

Hope some body can help me

I have about 500 power point files, most of them has weblinks that are pointing to other PDF files in a specific web server.
All these web links i had made manually

Now the web server adress is going to change (example):
OLD) http://domain.com/documents/file.pdf
NEW) http://domainnew.com/documents/file.pdf

I have seen that may be is possible using a macro, but i need the help and support from the experts like you because iam not an expert.



Best regards
