Hello Community
I want the user to upload only .pptx files through powerapps forms, in sharepoint list attachments.
The method i am using is not the right one as the user is also able to upload any file which has .pptx at the end (eg. 'abc.exe.pptx').
Is there any possibility that it can identify the extension of the file through some validation as anybody can change the extension by renaming the file which will not solve the purpose of restricting a particular file extension.
It should only limit the user to upload a .pptx file...can this be achieved?
Any help would be greatly appreciated.
According to this, checking the file extension is the best way to do this validation.
