Recursive problem

[HaBe1963]

Hi,

as many others overhere I am new to C++, that's why my script is looking very amateurish. My apologises for that. I have below script to list all files in directories and subdirectories starting from a defined folder. I have seen numerous scripts which tried to do the same, but was not able to find one which actually did the job.
Therefore I decided to invoke an array to store directories which were found to search these after the current folder was fully searched. The script actually is working fine for smaller folders and subs, but it looks like that at some point the script stops with an error. (I don't know if the output file is getting to big or if the script is aborted by an error in the script it self)

I have tried some things but I can not get it solved.

Any suggestion
