Explanation / Answer
This method OnePDF() is used to copy the contents of all mardown files in 'Contents' folder into a new file 'testfile.md' in the specified 'Contents/Workmd' folder.
This 'testfile.md' is later converted into a PDF file.
when the url is passed as 'Folder/onePDF/'
the method checks for the '.md' files in 'Folder/Contents' and creates a temporary'.md' file in Folder/Contents/Workmd/' folder as 'testfile.md' and converted into a 'testfile.pdf'
