Project files and folders
What is an Audacity project?
Saving an Audacity project lets you save unfinished work and re-open it later in Audacity exactly as it was, with all edits and recorded/imported tracks preserved. This is a different process from using one of the Export commands in the File Menu. Export creates an audio file like WAV or MP3. Use Export whenever you want to hear your work in media players or to burn CDs, because no other programs can open Audacity project files.
There is no need to save a project. If you don't, the necessary audio data is stored in the temporary folder specified in the Directories tab of Preferences until exiting the program. At that point, Audacity offers the choice of saving a project or not.
Some benefits of saving a project:
- No need to re-import or re-record files
- Fast loading, even of multiple long tracks
- Audio data always preserved in lossless quality. This is useful if you have already exported to a lossy audio format like MP3 but decide to edit the file further. Editing and re-exporting the project saves the additional quality loss of re-editing the exported MP3.
When you save an Audacity project, it creates two items inside the folder you specified for the project:
- a _data folder bearing the name of the project, containing its audio data (in the form of many 1 MB-sized uncompressed .au files).
- an .aup project file bearing the same project name, which is merely a text file that references the _data folder.
To reopen a saved Audacity project, click crash recovery page.and open the saved .aup file (not the .au files in the _data folder). In the event of there being no saved .aup file (for example, because of a crash or power outage), see our
- The current version of Audacity (and legacy Beta 1.3 versions onwards) do not write .aup.bak files and will not open any created by previous versions of Audacity.
Although you can share Audacity projects with people on other computers, it's necessary to send the other user both the .aup file and the _data folder, and the _data folder must contain a full copy of any imported files that the project contains. As the _data folder can become very large, it's often better to export a compressed file like MP3 and send that instead.
Audacity projects should not be used for long-term storage of audio. When you are completely satisfied with your exported file(s) and are certain you won't need to export further files from the project, delete the .aup file. the .aup.bak backup file (if there is one), and the _data folder, to save disk space.
Moving and renaming project files and folders
As the .aup file references the _data folder, both must be kept together inside the same folder in which you created the project. If you want to move either the .aup file or the _data folder, you must move both to the same new location.
For the same reasons, you should not rename the _data folder, even if you leave it in the same folder it was created in.
If you want to rename an existing project, the safest way is to do it in Audacity. This creates a new .aup file and matching _data folder with your chosen name:
- In the "Save Project As:" dialogue, enter the new name for the project in the "File name" box. Audacity will offer you the current name of the .aup file, so overwrite it with your new chosen name.
- Click the "Save" button.
To avoid confusion between the differently named versions of the same project, delete the previous .aup file and .aup.bak file (if any), together with the previous _data folder. The only legitimate reason for keeping the original project file and folder would be if you wanted to retain a snapshot of your project at a particular point in time before making further edits in the renamed project. If you do this, we recommend giving the renamed project the same name, but differentiating it by including a version number in the name.
Note that if you absolutely know what you are doing, you *can* rename the project manually. It is possible to just rename the .aup file and not rename the _data folder, but this is strongly discouraged and means you cannot make further changes to the project later on.
To rename the project manually so you can save further changes to it, you must follow these steps:
- Rename the .aup file for example, "renamed.aup"
- Rename the _data folder to the same name as the .aup file, for example, "renamed_data"
- Make a copy of the .aup file to be on the safe side
- Open the copy of the .aup file in a text editor such as Notepad
- Turn "wordwrap" off, look for the second line near the top of the file that starts
and change the projname inside the quotes to point to the correct _data folder; for example, if you renamed your .aup file to "renamed.aup", the start of the second line of the .aup file should be changed to:
Making a backup copy of a project
As with a rename, the safest way to make a backup copy of a project is to use.
- Click .
- In the "Save Project As:" dialogue, enter the name for the backup copy of the project in the "File name" box. Audacity will offer you the current name of the .aup file, so overwrite it with the new name. It is recommended to include the date and time of the backup in the file name, without slashes; for example, type:
which will save "backup_of_song_project_12Jan2012_10_33_AM.aup" and "backup_of_song_project_12Jan2012_10_33_AM_data".
- Click the "Save" button.
If you must make manual copies of projects, please do it this way:
- Make a new folder to contain the backup
- Select and copy the original .aup and _data folder
- Navigate into the new folder and paste the copied .aup and _data folder.
Because the copied .aup and _data folder are now in a different folder, Windows (or you) do not have to rename them. This way, the .aup file will always reference the correct _data folder.
Avoiding loss of project audio due to missing dependent file
Legacy 1.2.x versions of Audacity.
By default, Audacity imports uncompressed files such as WAV or AIFF by reading them directly from the file. This is normal practice with media editors and both speeds up the import considerably and avoids the rapid consumption of disk space that copying the file would involve. However, this means you need to keep the imported WAV or AIFF file available for Audacity to use, in the exact file path it existed in when you imported it.
Therefore the project will have either no sound, or sound only in places, if you do any of these:
- move the WAV or AIFF file to another location
- delete it
- rename it
- disconnect the removable source it resides on
- open the project on another computer without copying the dependent WAV or AIFF to the same path on that computer
This is true even though the waveform is visible on the screen, because the waveform is only a representation of the audio made when it was first imported. Any regions that do have sound will be those edited while the original audio file was still in place.
To correct this situation, open the .aup Project file in a text editor such as Notepad. The file(s) originally used to read data into the project are marked in the .aup file as "aliasfile". Use the text editor's "Find" function to search for "aliasfile" (without quotes), and note the full path to these files that is stated in the .aup file e.g. aliasfile='C:\My Music\Music22.wav'
Restoring the files noted as aliasfiles to the exact path noted in the .aup file, will restore full sound to the project.
To avoid this problem in future when importing uncompressed files, either retain the original audio file (in its correct location) or set Audacity to make a copy of the file, which will then be stored in the Project's _data folder when the Project is saved. To set Audacity to make a copy of the imported file, go to the, find "when importing uncompressed audio...." and check the radio button " ". Click OK to save the change.
- Note: this issue does not arise if importing compressed data such as an MP3 or OGG file, as Audacity automatically makes a copy upon import.
Current Audacity versions
In 2.0 versions onwards, you still need to keep the imported WAV or AIFF file available for Audacity to use, in the exact file path it existed in when you imported it. However, when you exit a project that depends on such files, Audacity will by default show a dialogue providing the option to copy the files into the project to make it self-contained. The dialogue also gives options to always copy data into the Project, never do so, or always ask what to do. These three options can also be accessed on the. This tab is called "Import / Export" in Audacity 1.3.5 and later.
File and folder errors
Directory write-protected or disk full error when writing WAV/AIFF
This tip applies to legacy 1.2.x and legacy 1.3.0/1.3.1 versions of Audacity.
You will receive the above error if you both:
- when importing uncompressed audio data such as a WAV or AIFF file, use Audacity's default behaviour of reading the data directly from the original file, and
- export your Project's audio data to the same file name and directory as the file you imported
The problem occurs because Audacity cannot delete the original file in order to overwrite it when it is already reading it. (This issue does not arise if importing a compressed audio file such as an MP3 file, because in the case of compressed audio Audacity automatically makes a copy upon import.)
To avoid this problem in legacy 1.2.6, either
- save the exported WAV or AIFF to another file name or another directory, or
- set Audacity to make a copy of the imported file: go to the , find "when importing uncompressed audio...." and check the radio button " ". Click OK to save the change.
In current Audacity, this problem is handled differently, and the steps needed in legacy 1.2.6 are not needed. If Audacity is set to make a copy of the original file, you can overwrite the original file just as in legacy 1.2.6. If Audacity is set to read directly from the original file, it will rename the original file by appending "-old1" to its file name, allowing you to export the edited audio as the original filename. Once you are happy with the newly exported file, delete the original file with the "-old1" suffix.
A context menu is the menu of options accessible when you right-click over a file in the operating system's file manager (for example, Explorer in Windows). The following information applies to Windows, but similar principles apply to other operating systems.
This context menu item allows you to open the file with programs other than the default program associated with that file type. You can add a program to the "Open with" menu and choose if that program will now be the default program to open that file type when you double-click it.
Once a program has been added to the "Open with" menu, it will be listed when you hover over "Open with". If you add Audacity to "Open with", this provides a way to open files with Audacity when it isn't already running, but retain the default double-click action to play the file with Windows Media Player. If a track is already open in Audacity when you execute "Open with", your file will be opened in a new project window.
- Use the dialogue to browse to the required executable each time.
- Alternatively, rename one executable to a unique name such as "audacity_2.exe", then use , browse to the renamed executable and make sure "Always use the selected program to open this kind of file" is checked.
To give more direct context menu access to Audacity, Windows lets you add a custom context menu item of your own for a file type, such as "Edit WAV in Audacity".
To create a custom context menu item in Windows 98, ME, 2000 or XP:
- Click , or from inside Explorer
- Click on the
- Navigate to the file extension for your context menu item, such as WAV, and click "Advanced"
- In the window that appears, click "New" to add a new context menu item (or to change an existing item, click "Edit")
- In the "Action" box, type or change the entry as you wish it to appear in the menu (for example, Edit WAV in Audacity)
- In the "Application used to perform action" box, type the full path to the Audacity executable inside quotes, followed by %1 inside quotes, for example:
"C:\Program Files\Audacity 2.0.0 (Unicode)\audacity.exe" "%1"
- Click OK, OK and Close.
Windows Vista and 7 lack any direct way to either create or edit custom context menu items. You can use a free third-party application called Default Programs Editor for this purpose.
"Open with" on Windows only supports opening one file at a time.
Using legacy 1.2.x versions of Audacity under Windows, you cannot right-click and open multiple files, or right-click and open any files if Audacity is already running; this will give an "Audacity already running" error. This is fixed in the the current version of Audacity. Each file will open in a new project window.
HOW TO open a too-large Audacity project
Recently I ran into a problem where audacity just wouldn't open my 11GB gigantic project. I did a recording of a radio show for about 9 hours. What i did was to divide the project into smaller ones - each about 2 hours. My recording was in stereo, 44100kHz, 16Bit.
- 1 - make a backup copy of your .aup file (name it project_orig.aup).
- 2 - make a template copy of your .aup file (name it project_templ.aup).
- 3 - open project_templ.aup and delete the contents between the <sequence ...></sequence> tags, contained in <wavetrack>. Note that there are 2 <wavetrack> tags in a stereo file!. You'll use this template to copy <waveblock> tags into.
- 4 - copy project_templ.aup to project.aup, open it and find the attribute "numsamples" in the <sequence ...> tag you already know. divide numsamples value by the number of parts you will divide your project into. i got something like 309000000. i rounded it off to 300.000.000. delete this numsamples="xxx" attribute of the <sequence ...> tag in both channels. audacity seems not to need it.
- 5 - copy the <waveblock ...> tags until their start attribute value exceed 300000000(x count of repetition) between each <sequence ...> </sequence> tags. note, for a stereo file you'll have to do this twice because there are two seperate channels (contained in wavetrack)... but i already mentioned this.
- 6 - bhu.. quite large file.
- 7 - open this project.aup file
- 8 - When audacity ask you "Project check found XXXX orphaned blockfile[s]. ...", answer with "Continue without deleting" - because this this was just intended.
- 9 - edit as you need. best thing is to export the file to a new aup project, flac, ogg or whatever.
- 10 - repeat the steps 5-9 until you're done.
- 11 - praise audacity because you wouldn't be able to record such a huge project with wavelab on windows.
