All Files in a folder renamed to Mu (μ) symbol
SD card corrupted

Files size loosing in a memory card

USBC files in memory card

USBC virus

Folder names are being changed to start with the character "μ." For example, my_music was changed to μy_music (this does not happen on the device's internal memory)



SOLUTION :=>

First of all just Check if there is folder named LOST.DIR in your memory card.


Then go to memory card drive (eg. Memory Card(G) ) -> right click -> go to Properties -> go to Tools tab -> click check now ->select both options (i.e. automatically fix errors and scan and attempt to fix bad sectors) ->click Ok




Now go to LOST.DIR , there you will see lots of files..that's your data

but its file format is different

so now you just have to change the file extension


for photos -> .jpeg
for videos -> .mp4




for changing extension of all files =>



go to command prompt (cmd) -> go to memory card drive (e.g. G: )
-> go to LOST.DIR folder ( cd LOST.DIR)


type following command :



ren *. *.jpeg

(this will bring back all your photos....now copy your photos to different location)





now for bringing back your videos

go to command prompt (cmd) -> go to memory card drive (e.g. G: )
-> go to LOST.DIR folder ( cd LOST.DIR)


type following command :

ren .*jpeg *.mp4

(this will bring back all your videos)


{ For renaming all files in a folder ,there is an app called "FILES TOOLS" in play store }
