Short answer
AskTuring automatically detects duplicates, even if file names are different, and blocks the upload.
Full explanation
When you upload a file, AskTuring checks the document’s content, not just its name. If the system detects that the file is already in your Index, it will prevent the upload and notify you that it is a duplicate.
This means even if you rename the file, the system will still recognize it as a duplicate based on its actual content.
