Program crashes due to rights issues #3
Description
So far, the program (at least the Part "PdfHeaderChecker", others will follow this example) can deal with all strange files on my laptop (and there are some really strange ones).
However, it crashes if a folder is chosen which cannot be accessed due to rights issues (e. g. "C:/"). It should be tought to omit these folders - check if it has rights or not - gives a short message and then continues with the folders which are ok for it to access.
