+# Using the vscode.didact.copyFileURLtoWorkspaceCommand
+
+We have added a new `vscode.didact.copyFileURLtoWorkspaceCommand` to handle two common cases: downloading a file into the workspace, and downloading and unzipping an archive file into the workspace. We'll cover both of those cases and the variations here.
+
+## Setting up the examples
+
+Let's say we have this image:
+
+![Spongebob Squarepants Finger Guns](https://media.giphy.com/media/7DzlajZNY5D0I/giphy.gif)
+
+We can find it at this URL: https://media.giphy.com/media/7DzlajZNY5D0I/giphy.gif
+
+And let's say we have this archive file: https://github.com/redhat-developer/vscode-didact/raw/master/test-archive/testarchive.tar.gz 
+
+## Copying a File into the Workspace root with no name change
+
+Let's say we want to copy it into our project. I've created a new command that takes the URL, the file name, and an optional path for the workspace.

+## Copying a File and Changing the Name
+
+* [Click here to let it do its thing, but this time we'll change the filename.](didact://?commandId=vscode.didact.copyFileURLtoWorkspaceCommand&text=https://media.giphy.com/media/7DzlajZNY5D0I/giphy.gif$$spongebob.gif)

+## What if we want to change the name and put it into a specific folder?
+
+This time we'll try a different Spongebob... we're getting excited!

+
+## That's all well and good, but what if I have an archive file I want to pull down and unzip at the same time?
+
+This is another issue (https://github.com/redhat-developer/vscode-didact/issues/135) that came up and now we can do that too! Let's take a sample image archive and unzip it into a new folder called `expandme`.
