How to manage blocked extensions
Back to Index
Sometimes, especially for educational organizations, administrators need to block certain file types by its' extensions, like
media content. For example, your students may exchange multimedia files and in such cases
they can copy content with prohibited copyrights.
Of course, this solution is not 100% proof: user can hide files into encrypted
archives, simply change extensions, etc. But we do not need to stop any
exchange of illegal content (it is not possible). Instead, we can make
process much harder - just imagine student needs to rename every file
while he want share music from his' iPod, before copying it to server.
Blocking by extension works independently to other components, so you are able to
specify start folder and specific account(s) that acts with blocked extensions
even without any quota limit defined. As other parts of WinQuota, all checks are
done in kernel mode, so simple tricks like killing application will not help.
You can specify either masks like
In this case all MP3 files will be denied completely at all drives. Or you can specify starting point:
In this case MP3 files will be denied for all sub-folders beginning from c:\home\john.
Additionally, you can limit extensions blocking to specific user or group,
to make life harder only for specific person(s). Both local and domain groups and users
are acceptable.
