How to detect a file in Azure blob storage from PowerApps

[Aria]

Hi ,

From powerapps I want to detect if a file exists in a AzureBlobSotrage such that I can use it to show  the stautus of  file upload from PowerApps to AzureBlobStorage.

The files are created on AzureblobStorage as shown below:

ForAll(Fotos;
AzureBlobStorage.CreateFile(path;fotoId& ".jpg";foto)
);;

Unfortuantly I can not use a variable to get the information about the uploaded file when I use ForAll(...) , and I can not use the following 
ForAll(Fotos;
UpdateContext({uploadedFile:AzureBlobStorage.CreateFile(path;fotoId& ".jpg";foto)})
);;

Hi @Aria 

If you want to check if a file exist in the specific container on the Azure Blob Storage, you can use the below expression:

If("PDF File.pdf" in AzureBlobStorage.ListFolderV2(LookUp(AzureBlobStorage.ListRootFolderV2().value,DisplayName = "testt").Id).value.DisplayName,"Exist","Doesnot Exist")

Here, first argument(PDF File.pdf) is the name of my file. testt is the name of container.

Hope this Helps!
