// I have had a nasty problem here, which should be remembered when occuring once again
// Since the change from chroot to a root path, the 64 byte string were too small
// So memory was overwritten, which really shouldnt be

// For now, I made the strings 256 bytes big, but this is just a temp solution
// The best would be to determine the max path length and base the strings lengths on that
// Or create dynamic strings, which grow bigger when filled
