I recorded a choir session and downloaded it to my Windows 7 PC - on initial download I could play the file - after listening and saving {?} the files show up in the explorer files as single files - lots of them and no sound can be had - the same files are on the SD card??? What can I do to recombine them?? :confused: :cry:

If you saved an Audacity project (.aup), open the .aup file from File > Recent Files or File > Open… See .

Then to use the recording in other programs on your computer, use File > Export.
