Hi, you have to distinguish between a Blob stored in Datastore whose limit is 1 Mbyte and a blob stored in the blobstore whose limit is 2 Gbytes
For the blob in the blobstore you access it by chunks via the api: see the byte range in http://code.google.com/appengine/docs/java/blobstore/overview.html#Serving_a_Blob To read those chunks, you have to use the BlobstoreInputStream and its read() method. See http://code.googlecom/appengine/docs/java/javadoc/com/google/appengine/api/blobstore/BlobstoreInputStream.html regards didier On Dec 2, 6:23 pm, Toby <toby.ro...@gmail.com> wrote: > Hi, > > I am trying to figure out how to programatically process a file from > the BlobStore.
