# Virtual Folders

## Overview and Introduction

Couchdrop is not a fileserver - but it has some traits of one. Everything in Couchdrop starts as a folder. But folders themselves are abstract and do not necessarily live inside Couchdrop. 

When you connect Couchdrop to Sharepoint or any one of the other over 50 platforms we support - you provide a folder name**.** This folder name acts as a filesystem location in Couchdrop.

Browsing that folder in the filesystem will not show the contents of Couchdrop - rather the files and folders that live in that external platform.

Uploading a file to that folder - via any means - will result in Couchdrop transferring the file to that provider or platform rather than the file living in Couchdrop.&#x20;

Thus - to send a file to an external SFTP provider - you would simply upload it to the right folder inside Couchdrop.
