I want to access and work on my remote documents (such as .docx, .xlsx, etc... and pdfs) from within my apps. For this, I have created a cifs mount point from a network sdcard (NTFS v3.1) to my android device in directory /mnt/routersd ; the problem is that some apps such as WPS Office or Adobe Reader don't offer directory list with access to root directories (Ofcourse, the device is rooted). My question is that how these apps can be enabled to explore root directory list such as /mnt/routersd in order for me to open my remote office documents and pdfs through those apps.
I want my mountpoint to be shown in WPS Office directory listing.
Or, to be shown in Adobe Reader directory explorer.
As you see, the pictures in the mountpoint is displayed by QuickPic.
Also, X-plore file explorer can explorer the mountpoint and do copy/delete operations in there.
So, how can I open my remote docs (/mnt/routersd) from within WPS Office and Adobe Reader apps?
