the issue is; i have a directory with sub-directories that contains many PowerPoints files, there are hyperlinks between the PowerPoints files.
when copying the whole directory to another computer or movable hard disk some hyperlinks works and some do not, as the full path is copied through from the original computer to the another computer or movable hard disk.
for example if the original computer path for a hyperlink is:
C:\Users\Solly\Documents\Church\Liturgy\Fraction\Epiphany Feast- as you have bestowed عيد الغطاس-إذ اعطيتنا.pptx#1. Slide 1

this is copied as it is to the other computer or hard disk and the link will not work.
other times the hyperlink is;
..\Fraction\0%20Fractions%20List.pptx
i.e. starts with ".." and this will work in the other computer or hard drive

how to have all hyperlinks work if moving or copying from one computer to another if moving the whole directory.
