Hidden Files on Memory Card



I have a memory card which has a few folders on containing almost 2gbs of pictures. the problem is that they dont show up in explorer. The folder properties say that the memory card has 2gbs used memory but when i enter into it, theres nothing there.

I have "show hidden files" option checked

i also found other threads and checked the registery and the show all and hidden checked balue values were all correct.

I also was able to backup and restore the files onto my harddrive but again the same thing is happening, the folder i put them in appears empty but is using up memory, also the backup file is 2gb and i saw all the filenames being backed up.

Anyone any ideas? it would be greatly appreciated

otherwise ill just pay £45 to get it sorted by pros
