title: how to open multiple files in pdfplumber?
body: <p>I have multiple PDF files created with Access DB forms. The only way I can extract text from them is using pdfplumber. Here is my code and it works perfectly for just 1 file.</p>
  <pre><code>import pdfplumber
  
  with pdfplumber.open('CS_page_1.pdf') as pdf:
      page = pdf.pages[0]
      string = page.extract_text()
      file_name = string[43:48]
      print(file_name)
  </code></pre>
  <p>I need to use this extracted string to rename this file and the 100 other files in the folder.
  What would be the best way to do it?</p>
