Do File Servers Automatically Sort Files by Type?

Do file servers automatically sort files by type, e.g., collects all PDF documents to one directory, and all pictures to another?

If you are having trouble copying from any pdf file, most probably it is a scanned document. In that case, the whole page is just one whole picture. No problem, still you can copy text from that file with the help of free software like PDFelement. Run the PDFelement on your computer and then import the PDF file that you want to edit. Select the option Edit Text in PDF. Click on the "Edit" button in the top menu and then click the option "Edit text and image object" icon. Then add or delete text according to your need.
