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 }
