A Symlink In computing, a symbolic link is a term for any file that contains a reference to another file or directory in the form of an absolute or relative path and that affects pathname resolution. This is with reference to my previous answer here , but with more relevant details. On Android 5 :. Being not Android specific but generally Linux related, symlink and bind mount see "Creating a bind mount" are out of the scope of this question, as the question is about emulation part mainly.
Why the emulation is here? Emulated filesystem is an abstraction layer on actual filesystem ext4 or f2fs that serves basically two purposes:.
Read Android's Storage Journey for details, the summary is:. Early Android devices were short on internal storage and relied on physically external SD cards that traditionally use FAT family of filesystem to ensure compatibility with most of the PCs refer to Microsoft's dominance on PC world.
When the internal storage grew in size, same filesystem was shifted to internal still called "external" SD card. Execute following commands:. Now Force Stop the Termux app and grant Storage permission.
Execute the commands again:. See the difference in permissions of same files and directories.

Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Usually the easiest way to fix the problem is to just clear the MediaStore databases to get the bad entries out of the MediaStore Database and let the system reindex the files and put into the database with the proper paths. When you are done the files should show up with proper directory tree and be visible from the PC.
Depending on amount of files on the phone it can take as minutes to rebuild the media database as the service walks the phone directories, getting meta data, creating thumbnails, etc. Android recommends that you call Environment.
So you use the below code. Here you can use a finder-like structure. There open each picture one by one, go on setting three dots..
