Default [Q] after 4.3 update internal sdcard data inaccesible

hi, I have another problems with update

I flashed 4.3 update, and noticed that I dont have my pictures, search in sdcard and there is any of my files, but... free space is exactly the same, i made a scan using disk space for examinate space structure and appears lot of used space, my files, as system space, more han 6 gb, but I cant access it,

I tried access through root explorer looking in all folders but I cant find my files, but there is, free space in sdcard is exactly the same before flashing

what is the problem? why happend that?
