makedirs error: can GAE Python create new directories (folders) or not? <p>I have seen a number of questions relating to writing files &amp; creating new directories using Python and GAE, but a number of them conclude (not only on SO) by saying that Python <strong>cannot</strong> write files or create new directories. Yet these commands exist and plenty of other people seem to be writing files and opening directories no problem.</p> <p>I'm trying to write to .txt files and create folders and getting the following errors:</p> <p>Case #1:</p> <pre><code>with open("aardvark.txt", "a") as myfile: myfile.write("i can't believe its not butter") </code></pre> <p>produces "IOError: [Errno 30] Read-only file system: 'aardvark.txt'". But i've checked and it's def-o not a read only file.</p> <p>Case #2:</p> <pre><code>folder = r'C:\project\folder\' + str(name) os.makedirs(folder) </code></pre> <p>produces "OSError: [Errno 38] Function not implemented: 'C:\project\folder'"</p> <p>What am i missing?</p>
