Why does my sd card not shows any data on it?

[AC Question]

I am using lava iris Alfa l android phone.

Root access is not properly installed on my mobile.

After rebooting, SD card shows its containing files, but after sometimes, it shows nothing.

I have deleted some misc. Files ( files name started with (.) Ex. .estrongs etc ) from setting>storage.

I'd first address the 2nd line of text and fix your root access if you are gonna have it rooted.

Are you able to see the files if you have the card read by a pc?
If not then card is corrupted and you need third party software to recover them.
If the pc sees them, the it could be the card isn't mounting correctly and therefore the phone cannot see it.
