.aup File Extension

Developer: Audacity
File type: Project File
You're here because you have a file that has a file extension ending in .aup. Files with the file extension .aup can only be launched by certain applications. It's possible that .aup files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .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.

how to open a .aup file?

a word of warning

Be careful not to rename the extension on .aup files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .aup. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
