When extracting archives directly to removable storage using Windows Explorer with data control enabled, you may receive multiple conformation dialogs and extraction may be noticeably slower.
First seen in Sophos Anti-Virus for Windows 2000+
Extraction is slower as a result of checking all files being extracted comply with your data control policy.
If performance is causing issues for your users they could consider extracting files locally prior to copying the files to removable storage.
