Haven't had to deal with it because it's someone else's headache. I knew about the file identifiers in XP but never knew the specifics and had forgotten most of the rest. Never head of ZoneStripper before. We use the Xceed libraries for zipping and unzipping in our apps, so it must be handled there.

Windows XP SP2 writes a Zone Identifier on all downloaded files. So your zip file is marked as originating from the Internet. When you unzip the archive, your zip file manager has conveniently written the Zone Identifier to each file contained in the archive. Thus your solution file is marked as originating from the Internet and is thus not fully trusted. This behavior can also occur if you copy the code from a network share to your local drive using Windows XP SP2. ZoneStripper removes the Zone Identifier from files and directories so that the solution can be loaded into Visual Studio .NET without the security warning. How does Windows XP SP2 record the Zone Identifier? The Zone Identifier is saved into an Alternate Data Stream (Zone.Identifier) on NTFS. One way to remove the Zone Identifier is to move the files onto a FAT partition and then move it back to your NTFS drive. (FAT doesn't support Alternate Data Streams and so the Alternate Data Stream is ignored when copying files onto a FAT partition.) The other option is to delete the Zone.Identifier Alternate Data Stream, which is what ZoneStripper does. To see the Alternate Data Stream, simply type the following: notepad.exe Readme.htm:Zone.Identifier Unfortunately the .NET Framework's System.IO classes are not Alternate Data Stream-aware. So you must use P/Invoke to call the underlying Win32 API CreateFile (to determine if the Zone.Identifier stream exists) and DeleteFile (to delete the Zone.Identifier stream). Don't even TELL me you didn't already know all this!!! ;-) John W.

I can't get it do deal with either. Currently (latest) was: \\StoneHenge\Dev\VisualStudio2005\Projects Unfortunately to then access this location I have to be able to see the workgroup, and more specifically the Stonehenge server and it's shares, which I cannot. Sometimes I think I should have just become a doctor. It would have been so much easier. John W.

As I recall, it refuses to deal with mapped remote drives, so you might try the full UNC path.

Now Visual Studio complains that the source is not trusted and may cause exception errors. In looking on the web it says to use the framework configuration application to set a trusted zone - machine / codegroups / allcode / local intranet zone / add a child code group. I did that but I cannot persuade Framework 2.0 to trust the path I set, and of course it does not supply a file find dialog to browse for the location. Can anyone help me out here? What do I need to do to get this thing to work? The hours I waste trying to do stuff that should be made simpler! John W.
