How do I check if a MicroSD Card is inserted using an extension. I have been searching on Google and no luck. I need help with doing this. Please suggest any extension that can check if a MicroSD Card is inserted.

you can try the file extension and its AvailableStorageDirectories method, which returns a list of available storage directories
if the length of that list is 1 then there is no external sdcard available

So the solution is to check for the /mnt/sdcard/ folder?
