How to detect a file in Azure blob storage from PowerApps

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.MicrosoftTeams-image (7).png

 

Hope this Helps!

Hi 

Thank you very much for your answer !
I used your suggestion and it solved the problem.

I tried this if condition and it is not working in some cases, though the file is available in azure blob it is not coming up here, Is there any limitation in picking up data from blob storage.
