=== Retrieve deletion logs from the USB flash drive ===

'''Important:''' On some PCs, for various reasons, shredos may not be able to write the deletion log to the USB flash drive. You will then need to take a screenshot of the screen showing that the deletion has been completed.

The deletion is now complete and we can turn off the computer and insert the memory stick into another PC to retrieve the log. 

The file name is structured like this:
nwipe_log_YYYYMMDD-1234567.txt
A log created on October 16, 2023 looks like this, for example:
nwipe_log_20231016-211631.txt
This means that the log was created on October 16, 2023 at 9:16:31 PM

The PDF log is structured like this:
nwipe_report_2024-09-12-2024-20-10-28_Model_<harddisk-model-and-model-number_<serial-number-of-the-harddisk>.pdf
The logs can now be stored locally in, for example, a cloud service and can be forwarded to the donor with a link via email.
