I have just got a 16gig micro sd card with my Granddaughters data on it.
I managed to delete almost completely all the data but there are ten
files that will not delete either on the phone or my computer the phone
say the files are deleted but they remain the computer returns a "could
not delete" error.
I tried "sudo apt-get install mtp-server libmtpserver-dev"
But got a error msg unable to locate mtp and libmtpserver.
Any one can help please................
