# PermissionError: [WinError 32] The process cannot access the file because it is being used by another process:
This occurs in Windows. The reason is the program is trying to work with a file that is open. The error is generally followed by a filename which is open and therefore the error occurs. User must close that file
# Not all files are watermarked/encrypted or not all files are included in the final ZIP archive
This happens if the filename is not given according to the naming scheme i.e *<matriculation number>_<Nachname>*. The program will not pickup a file whose name doesn't follow this scheme.
# "Command 'python'/'python3' not found" or "'python'/'python3' is not recognized as an internal or external command, operable program or batch file."
This can happen because:
* Python is not installed
* Environmental variables for Python is not set. This issue mostly happens in Windows if one forgets to check 'Add Python to Path' [checkbox](./images/pythoninstallation.png) during installation
* You are usaing the wrong command variation. Try running the program with the other command variation.
# "Invalid Syntax"
This can be because you are running a Python version that is incompatible to the version of Python this was developed in.Check if the python version is higher than 3.0 preferrably 3.8 or 3.9.
# python: can't open file *<current directory>*/watermark.py: [Errno 2] No such file or directory
You are not in the correct folder to run the scripts. You must run the program from inside the extracted folder of the Git repository
# The ZIP archive has locked PDFs. Where can I find passwords?
If you are running individual scripts, the passwords are saved in passwords.csv under pdfs_encrypted folder.
if you are running the batch job script, the passwords are saved in out > password.csv
