Many small strips of sound

Some years ago I recorded many small sequences of 3 or 4 minutes. Today I need to read them but it turns out they are split into small sections of 15 or 20 seconds. : Cry:
How could I put these small sections together?
NB: I just downloaded and installed the latest version of Audacity.


You probably saved Audacity Projects.

Can you find the AUP files associated with each Project? The AUP file contains the Audacity instructions how to put your shows back together from the contents of the _DATA folder of the same name. Double click the AUP file to open a show.

Audacity doesn’t save sound files. It only saves Projects. To make a stand-alone sound file, you should File > Export one.



Thanks a lot!
Now that’s clear for me!
