how to display and provide a customer folder in Sp folder

Hi Aakash,

 

This is the my client requriment 

 

TTS is the folder in that we can select that information create automatic folder stored that folder

 

 

Automatic generation of document sub-folders based upon a standard in customer TTS folder. 

Can you please explain in detail about your requirement?'

 

As per my understanding, do you want to create a folder in SharePoint folder and share that folder with your customer? 

 

If this is the case, then yes, you can do that.

 

SharePoint have folder level permission, so you can break the inheritence on the document library or particular main folder and then you can assign permission to your customer on the folder.

 

But this might need your customer's account in your SharePoint or it may work with external sharing. I haven't tried external sharing at folder level.
