What is an aup file and how do I open an aup file?
The AUP file extension is a data format associated with Audacity Project. AUP files and Audacity Project were developed by Audacity, a free sound editing and recording software. These files contain references and applied sound edits of audio files created in the Audacity Project. Specifically they store number of tracks, time positions, clip details, labels and volume automation. These files are saved in XML format and can be opened in a text editor. The Project consists of the AUP project file and a _data folder with sub folders in it. The a_data folder uses the DAT file extension and is ensured that they are in the same directory as the AUP files. It allows breaking of longer audio tracks to smaller pieces or chunks so the software open and save projects quickly. Files in AUP format can be opened with Audacity in Mac Os, Microsoft Windows based systems, and Linux.
