What are "_vti_cnf", "_vti_pvt", "_vti_script" and "_vti_txt" folders ???

Question

This folder appear in my dotnet Web project. Why? Does are usefull?

Answer 1

They're part of the legacy FrontPage server extensions. The _vti_ prefix refers to Vermeer Technologies Inc., the original developer of FrontPage which was subsequently bought by Microsoft. They would appear if you installed these IIS extensions - they're not needed unless you have a legacy client which requires FrontPage extensions to be there.

Answer 2

They are used as part of the FrontPage server side extensions which do

• change tracking (mostly the _vti_cnf)
• code/script used by FrontPage specific controls (mostly the _vti_script)
• general settings

The old FrontPage program and Dreamweaver both used it.

The VTI part is actually because FrontPage was originally created by Vermeer Technologies Incorporated (note the acronym) and then bought by Microsoft and it just stuck.
