Create large file in Azure Blob Storage

I am trying to create (upload) video files size >100MB to my azure blob storage using the AzureBlobStorage.CreateFile function. While it works well for smaller file sizes, for files >100MB I get a return error "Status 413, The request is larger than 104857600 bytes".

 

I've also tried by passing the base64 to the Create blob V2 action on a flow and again it works for smaller files only.

 

Is there a way to send these large files in smaller chunks? can PowerApps handle this?

Experiencing the same problem here. The documentation on this connector refers to the maximum file size being 1024 MB (1 GiB). This doc however refers to whether or not chunked transfer is enabled, and the spec on this "CreateFileV2" endpoint doesn't refer to any such option.

I have sunk a good amount of time building this solution as a canvas app connected to our blob storage embedded in a model driven app as we are dealing with a significant amount of archival data (video, photo, &c.). Quite frustrating to know the framework is all there to support this use case, but this undocumented limitation exists that we couldn't have known about upfront.

@alexkillby: I know this is now over a year old, but have you found a solution or another way to upload larger files to Azure Storage?

Unfortunately not - no response or private message from this question, and we had to resort to using Azure Storage Explorer with a significant number of manual steps to bypass this limitation for larger assets.

 

Very time consuming and error-prone. We were looking to Power Platform to allow us to automate this task.

@VIP0289Only similar to @alexkillby s solution, doing it semi-manually...

Yea only solution we've come up with that im working on implementing is a link in the app to the Azure Blob Stoage, manually upload the file, another button in the app to run a flow that will find the last created file so they can confirm if thats the correct one and then write those links to a dataverse table for storage. Only 2 users on our app so not a big deal but definitely not the best workaround
