How to Save Files Temporarily in Azure Functions?
Asked by

Hey everyone, I'm facing a challenge with saving files to the Azure file system. We have a use case where we need to save files for a short time and then delete them. Locally, everything works well, and files are saved in the Files folder. However, once I deploy to Azure, I get an error saying "Invalid path, path not found." Is there a way to save files in the Azure file system? Thanks in advance!

You can indeed mount Azure Files, but I would suggest using temporary Blob Storage like some others mentioned. It’s a more robust solution for what you’re trying to achieve.

You need to make sure you're getting a temporary file path from the system. If you’re using .NET, you can use System.IO.Path.GetTempPath(). Keep in mind that local storage in Azure Functions is temporary, so files might not persist between executions. But for your use case, a durable location like Blob Storage for input/output is essential.

It sounds like you might want to rethink that approach. Generally, cloud environments like Azure aren’t meant for temporary file storage like a traditional server would be. It’s better to use Blob Storage for saving your files instead. Trust me, it’s the way to go!
StorageWizard42: Absolutely! Setting up Blob Storage is really straightforward and perfect for what you need.
TechSavvy14: Exactly! Blob Storage is ideal for short-term file storage. You can just upload and delete when you're done.
