Samsung tablet android 6. There is an Sd card but cc library is actually in main storage. Cc says the path to the books is storage /emulated/ 0/ cc.
Moon sees the path to the same books as ...sdcard/cc
I guess one is symbolic, one is actual but neither program will use the other path name convention.
Moon uses the path name when it adds a book to recent list, so I get duplicates if I open two different ways, because there are two equivalent ways to define the path.
ie to moon , ...sdcard/cc/book1 is not the same database entry as ...emulated/0/cc/ book1 even though both path formats lead to the same place
How can I fix this?
If I browse with moon to find the cc library and drill down from / (root) into /storage, then moon immediately changes the path descriptor to ...sdcard.
If I start with cc and try to define a library location, I cannot use sdcard as a path to internal storage because cc cannot see such a path option.
Is there a way to set up the library location so that they agree to use the same path name

On my fire tablet, android 5, no Sd card, I was able to get both to agree on using ...emulated/0... but I cannot get that to work on the Samsung.
