When extracting a sensitive zip file, all extracted files are marked sensitive.
All the extracted files are marked as sensitive when extracted by default explorer windows unzip. This is to prevent the leakage of files present within the sensitive zip file. Third-party non-enterprise unzip applications are not allowed to access sensitive zip files.
While sending attachments via your Outlook email, you can zip multiple files together and send them as a single file.To see the individual files in the zip file, you can use the "Show embedded attachments" option.
