title: iPython notebook not uploading my .txt file
body: <p>I converted some excel files to .txt files (Text (tab delimited)), carefully saved them in the same folder as my notebook, made sure there were no copies anywhere on my computer, checked the .txt files could all be opened in Notebook, and after using the command '%pylab inline' to load all the functions I usually use, triple checked that mt .txt files were in the same folder as the notebook by using the 'ls' command. I then used loadtxt('filename.txt') to load my data and it gave me errno 2: no such file or directory: 'filename.txt'. I triple checked that I had spelled everything correctly and I can't understand why it's not working. I need these data analysing today for a lab report due in tomorrow - help! Here's my code:</p>
  
  <pre><code>%pylab inline
  ls
  loadtxt('Physical_lab_experiment_2_25_degrees_with_times.txt')
  </code></pre>
  
  <p>and here is the error:</p>
  
  <pre><code>FileNotFoundError                         Traceback (most recent call last)
