Python 2.7 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Python
2.7 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Python.

google.appengine.api.blobstore.file_blob_storage module
Summary
In-memory implementation of Blobstore stub storage based on file system.
This module contains an implementation of blob_storage.BlobStorage that
writes blobs directly to a file system.
Contents
- class google.appengine.api.blobstore.file_blob_storage.FileBlobStorage(storage_directory, app_id)source
-
Bases: google.appengine.api.blobstore.blob_storage.BlobStorage
The storage mechanism that stores blob data on a local disk.
- DeleteBlob(blob_key)source
Deletes blob data.
Deleting an unknown blob will not raise an error.
Parametersblob_key – The blob key of an existing blob that you want to delete.
- OpenBlob(blob_key)source
Opens a blob file for streaming.
Parametersblob_key – The blob key of an existing blob that you want to open.
ReturnsAn open file stream to read the blob.
- StoreBlob(blob_key, blob_stream)source
Stores a blob stream .
