I was getting a routing error for a web app that points to a certain file. Deleting the file and recreating it seems to be the only fix. When I command+P filename search the file a box with the letters DLE is appended to the filename and the extension. See the following screen grab: https://www.dropbox.com/s/zrak2novs2wx2 ... 2%20AM.png
Please advise if there is any additional information that you may need. Any assistance in this matter is greatly appreciated.
