If i try to open my opera folder (336 subfolders) MPtagThat unfortunately crashes with "System.OutOfMemoryException"! Opening every folder separatly is working fine!
I fixed now the crash.
However the out of memory can occur at any tome anywhere in the programn, so i only can inform the user that there's no memory and terminate the app.
I was able to scan 15k files, before it happened to me.
i think there is no practical use for it anyhow.
An option would be to stop after e.g. 7000 files and show what we have found so far.
