I created a Folder1 in SharePoint, and within Folder1 there is a SubFolder2. Both Folder1 and SubFolder2 may occasionally have documents uploaded, such as Excel files. Now, I need to implement the following: when a .xlsx file is uploaded to Folder1, an email notification is triggered to inform me of the new file arrival; when a new .xlsx file is uploaded to SubFolder2, no action is taken and it is directly filtered. My current difficulty is how to set up the conditions to filter out SubFolder2?
