You may have noticed that with Windows XP SP2 files downloaded from the internet are now marked as such. This marks the files as unsafe.
This results in a number of problems.
- Compiled help files do not work correctly (the content doesn't display)
- .Net projects are treated as unsafe and so imposes restrictions on what can be done.
What I have found today is that zip files whilst treated the same also cause this setting to be propogated to the files extracted from the zip file when the built in "Extract All..." function is used. Once the files are extracted I am not aware of a way of globally marking the files as safe (unblocking them).
To stop this happening make sure you unblock the zip file before extracting the files. In doing this the files will be extracted as unblocked.
To unblock a file display the file properties and click the "Unblock" button.
