wah that sux considering that i have created quite a plenty to better organise my photos on my sd card.
for days liao still doing my photo recovery. tedious doing manual picking of photos to recover and then matching the 'time taken' of those pics to the ones of the filename of 0kb photos that i have lost (no way to preview except to use the date and time on the filename to match)
I did 1 experiment last night.
Used quickpic to bulk copy an entire album of photos several times onto the SD card
Not all of the photos came out 0kb when read by the PC. In fact for each time i tried copying, different combinations of the files were 0kb and not 0kb (readable as normal).
Repeated the copy experiment, this time using Solid Explorer instead of quickpic, similar result.
Deleted the copied albums using solid explorer, plug phone into PC, on the SD card, it shows the albums are still there.
Which leads me to believe that it's definitely a bug on the software side and not some file-locking thing that LG added into MM.
In the end, I managed to get all the photos onto the PC by mounting a OTG usb drive, and copying to the drive, then taking the drive and plugging it into the PC
