samsung – How to link chrome html files together on android

I have multiple chrome html files on PC that are all linked together.

For example, there is a table of contents and if I click A it will then open the html file for A and this can be then used to go back to the table of contents or I can go to B).

However, putting all these files together on mobile (SAMSUNG S8+ Updated up to date) does not allow them to be connected no matter which web browser or html viewing application I try to use (Clicking to go to another page just gives an error saying the other html file cannot be found). Additionally, the images part of the html document do not seem to load on mobile despite being in the same folder still.

I am wondering if there is a way to have all of these files linked on android as it does on PC.
