If I may make an observation - if one doesn't know the cause of the problem, then one may not be looking in the right place or using the 'correct terms' in a Google search (?) Furthermore, a good set of search results will depend on the structure of the search term. Absolutely, I quite agree, but I...

My files were saved into a folder named 4-18-15 Data, do you mean: "4-18-15_data"? If so, then that is the audio data belonging to a project that you saved as "4-18-15" and there should also be an Audacity project file called "4-18-15.aup" The .aup file and the _data f...
