I have tried the following regex :

 ^(.*?/|.*?\\\\)?([^\\./|^\\.\\\\]+)(?:\\.([^\\\\]*)|)$

Validating a folder name correctly can be quite a mission. See my blog post Taking data binding, validation and MVVM to the next level - part 2.
Don't be fooled by the title, it's about validating file system paths, and it illustrates some of the complexities involved in using the methods provided in the .Net framework. While you may want to use a regex, it isn't the most reliable way to do the job.
