I have a Nikon Coolpix L22.
Having found a number of files missing on my original SD card I copied most of them from backup and now have no free space and receiving 'Out of memory'. Prior to this there was no problem in reading files on the camera.
I purchased a larger capacity SD card and transferred the file NIKON001.DSC to the root folder and all files in the folder DCIM (DSCN.0000.jpg in sub folders 100NIKON) to the new SD card. The files are readable when the new SD card is connected to the computer but not readable when the new SD card is in the camera. I suspect the file NIKON001.DSC may be the culprit as the last modification is dated in 2012 but it worked OK when using the original SD.
How can I get the camera to read DSCN files on the new SD card please?
