VBA to get PowerPoint to look for links from Excel in same folder

Dear All

I am looking to share an Excel and PowerPoint linked files. I have tried to link these files in OneDrive and Dropbox and then share these files but I find that the process is taking too long and crashes at times. There are link 100 links between the files.

As such I am looking for a VBA that would assist the PowerPoint file to look for the Exile file in the same folder, like we could do before 365. The idea would be for a colleague to download these files, put them in the same folder and open up the files and the links work.

Thanks
Darryl
