Ok, so are you able to remove the SD card without adverse effects? Try doing that and reconnecting your phone to the PC and see what displays.
Well, Many strange facts came in front .
1. First I switch off the mobile, took out the memory card from the mobile, start the Mobile, now here after start I cannot access the file manager, it says you don't have SD card. Then I connect the phone with the PC , i saw no storage. Then I install a software Syncios in my PC and this one already installed in my phone, tried to find out the videos but I couldn't find out any. only apps contacts sms were there. I have tried to find any storage or something like that from that software so that I can access it from my PC but no luck.
I have also tried to check the memory card with a card reader in my PC , but a Marshmellow change my filesystem of that memory card, so couldn't access that.
Now again I switch off the mobile, put the memory card back in my mobile again. Now I can see all the files folders including the Zolo folder. Tried to delete it from file manager but same error. Now I connect it to my PC and YES, I can see now that folder Which I couldn't found before, well I immediately click on the folder and Shift +Delete . But strange, I didn't find found any error, I goes off. then I unplugged the USB cable and tried to check out but OH NO !!! it is still there, again I tried to delete it from my file manager from my mobile same error, Now I again connect my mobile with my PC , but this time I couldn't found that folder from my PC, but yes it is there in my mobile.
I don't know why this weird happens. 1st time I checked it is there, I delete from my PC, I wiped off, but it didnt actually, next time when I connect I cannot see that folder in my PC. I am totally confused now.
