Saving a Power App app to a local drive, and opening it
If you have a complicated app with lots of connections and resources, you'll probably want to package it and export it as a solution, as described here. However, for simple apps this is a lot of work - there is an easier way!
Step 1 - Saving your App to your Local Drive
Start by saving a version of your app to a local drive:
While editing your app, choose the Save as option from the File menu to save it with a new name (and location).
Choose to save it to your local computer:
Choose to save the app not to the cloud, but to your computer.
Click on the download button to create a copy of the app on your computer:
Click on this button to create a file with extenson .msapp.
You can now view the file in your downloads folder:
You can click to copy or access the file in the normal way (this is the link you see for an app called temp in the new Edge browser).
Step 2 - Importing the App from your Local Folder
Having backed up or saved an app as above, you can load it (perhaps into a different environment, although see the notes on versions below):
In Power Apps, click on the Apps tab on the left-hand side to view your apps.
Now choose to create a new app:
It's not really the obvious thing to do, but to open an app you've saved to your computer you first need to create one.
You can now choose to open an app:
Choose to open an app.
Find and double-click on the app you've saved:
Find the file you've saved, and open it.
Depending on which tables your app points to you may now need to repair your data sources.
A warning about versions
When you export an app, you can see which version it is by looking at its details:
Click on the ellipsis button to the right of an app to see its details.
You can then click on the Versions tab to see which version of Power Apps each version used:
The version number is shown boxed.
The reason this matters is that if you try to load a saved app into an environment, it must have the same or later version number, otherwise you will see this message:
While I'm sure it's possible to upgrade the version of your app, it's easier not to have to.
