Hi,
Ive recently been contacted by a new company wishing myself to do alot of flow work. The job is fairly simple to transfer files from one area to another (ill probably end up building them a custom app giving the files IDs and a naming convention so they can all be sorted by client, user and asset etc) However the potential client has very large video files that need to be transferred? ive done this before using large images and files etc, but what are the limitations of maximum file size transfers over flow? say between a powerapp attachment added to sharepoint list and then synced to onedrive? ive googled however i cannot find a empirical answer?
If the job is to transfer say a 500Mb file can flow do it from a powerapp? can flow transfer it in the background from a external app to sharepoint/onedrive?
Im just curious to give the client exact numbers and i am unable to find this information out by using google or the wiki..
Flow will not be able to transfer 500 MB from power app. And power app to flow does not allow chunking. You will have to roll your own solution with this.
Now, If you have to have this screen within power app, there is a way.
You need to create a custom pcf code component and call azure functions directly from the pcf component. Note that azure functions also have a request body limit and api timeout limit. You will have to chunk the file yourself.
There is an open source file upload client called filepond. It does chunking for your automatically. You just need to write an azure function according to its spec and upload the file to blob storage.
You can import the pcf component into your power app like any control. Obviously, if it's not apparent already, you will need programming knowledge.
