#26 problem with the reading size (create data disk)

[stdimitriadis]

i tried to create a back up of my documents and i overcame the size of the dvd so i deleted some files.
some times during that procedure the size wasn't reduced
and when the files's size were on the right size ,i put the button burn and the size became 0 MB.so the procedure
was stopped even though the files were on the left window
ready for burning
