I can't add folder in VC7 workspace(sln).

[nobut0]

When I open workspace(VC7 .sln type), I can't add folder.
I add a folder in project, then I see error message.

That error message is 'project ".....vcproj" is not recognized as valid'.

After then, I can't read source sln file by Visual Studio .NET.
Source vcproj file was broken.

ps.sure I use SlickEdit.

Thanks for reporting this. We are working to improve our support for VC7. Microsoft has made changes to their project and solution structure and we're working to catch up.

In the meantime, it's probably best to make structural changes to your solution within VC7. You should be able to add files in SlickEdit, though.
