On systems with McAfee Endpoint Encryption for Files and Folders version 3.* installed it is not possible to extract files from an archive by dragging the file from 7zip into a folder. Doing so results in the following error message from EEFF:
The possible cause to this issue in McAfee knowledge base article KB73498 (https://kc.mcafee.com/corporate/index?page=content&id=KB73498):
"7-Zip is an open-source application that functions differently from the commercially available WinZip archive application. WinZip keeps the temp folder file until the WinZip application closes to ensure that the copy operation completes. 7-Zip removes the temp folder file before the copy operation is able to complete."
