Error Loading TeamMentor Libraries : The fully qualified file name must be less than 260 characters

Tonight, we found an issue in TeamMentor 3.3. I realized that the default library Top Vulnerabilities was not being displayed in TeamMentor. After looking at the debug page, we found that the name of the folder was breaking Microsoft’s folders and files constraints : 260 characters.

Doing some tricks with PowerShell and O2 we found that the current length of the file was 264 characters, please see the below image.


Fortunately we had a background in this issue, Dinis wrote about it here  and here  and Roman already had opened an issue here , which is somehow related.

After doing  a quick review Dinis applied a fix and it seems to be working now.
