|You may be working with other users and want to send your multi-track Project to them so they can contribute to it. Or perhaps you created a five minute message with some music and want to send it to a relative by email.  Or what if you want to open your Project on another of your own computers running a different operating system?
Are any of these possible?
==Sending Projects to others==
It's quite possible to send an Audacity Project to another person
or open it on another computer of your own, so that the Project can be opened in another copy of Audacity with all the tracks, label and envelope information in situ. However when opening the .aup Project file you need to have its associated _data folder with the same name as the .aup file present in the same folder. For example, if you were sending a Project to someone else  you could include these in the contents of an attached .zip folder compressed with {{external|[http://www.7-zip.org/ 7-Zip]}} for Windows, {{external|[http://www.stuffit.com/mac/expander/index.html Stuffit]}} for OS X  or similar program. Then have your recipient extract both the .aup file and _data folder to the same directory and open the .aup file from inside that folder.
In practice, the problem with sending such a folder to someone else is the size of the _data folder. At Audacity's default
32 bit float sample format and 44 100 Hz sample rate, stereo Projects take up 20 MB of space per minute, and more as soon as you start editing them. This rules out most email transfers. You can transfer larger files over the internet with a service like {{external|[http://www.yousendit.com yousendit.com]}} but for very large files this is unlikely to be free. For example, the yousendit.com free service permits sending files up to 100 MB in size, with a charge for larger files. However you can always combine your .aup Project file and _data folder in a .zip folder, burn this to a data CD and send it by snail mail. 
There are other restrictions on opening an Audacity Project on
another computer:
1) If the Project contains audio data that was imported into Audacity from a WAV or AIFF file, you must have previously set Audacity to make a copy of that original audio when you imported it, so that it's included in the _data folder. You set this option on the File Formats tab of Preferences: ("when importing uncompressed audio....make a copy of the file before editing").  This is not an issue when importing compressed audio like MP3 or .OGG as Audacity always copies the audio into the _data folder.
2) If the person you are sending the Project to has a 1.2.x version of Audacity you will need to save the Project in a 1.2.x version of Audacity, because 1.2.x versions of Audacity cannot open Projects created in 1.3.x versions.  If the person you are sending the Project to has Audacity 1.3.2, the other person should be able to open it even if you created it in 1.2.x, but ask them to back up the .aup file and _data folder first to be sure.
3) If the person you are sending the Project to uses Audacity 1.0.0 (users on Mac OS 9 are limited to this version of Audacity), you must create the Project in 1.0.0, because 1.0.0 cannot open Projects created in 1.1.0 or later. If that person sends you a Project created in 1.0.0, you should generally be able to open it in 1.1.0 to 1.2.6, but Audacity's conversion of a 1.0.0 Project to the new format used by 1.1.0 or later does not always work. You should not open Projects created in 1.0.0 in the Beta 1.3.x versions of Audacity. 
4) If the person you are sending the Project to is on a different operating platform (e.g. you are on Windows and the other user is on a Mac), you must create the Project using Audacity 1.2.2 or later, and the other user must be using 1.2.2 or later. Prior to 1.2.2, .aup Project files are not portable between different operating platforms.
=='''Sending an exported audio file'''==
You can always send an exported audio file (such as an MP3) from your Project to the other user. If your Project only contains one stereo or mono track, only Project–specific information such as label and envelope data will be lost by doing this. But if you have multiple tracks in your Project, Audacity 1.2.x will always mix these down to a single mono or stereo track when exporting to an audio file. To get round this you can:
1) send each track from the Project as an individual audio file. The recipient can then shift-select and multiple import them into separate tracks of an empty Audacity Project.
2) use Audacity 1.3.2 Beta which can export the individual tracks in a Project as one multichannel audio file. So if you had a Project with 6 mono or left/right tracks, it could be exported as a one 6-channel audio file, and any 1.2.x user of Audacity can open that file and see the 6 channels displayed as individual tracks. To use multichannel export you must go to the File Formats tab of Preferences and turn on "Advanced Mixing Options" in the "When exporting tracks" panel.
To export your Project as audio file(s) you use the <span  style="background-color: #CCFFCC"><font color="#a0522d">File > Export As...</font></span> command. If you export as a WAV or AIFF file this enables you to send the file with no loss of audio quality, but the audio file would take up 10 MB per minute for a stereo file of CD quality (44 100 Hz, 16 bit). However if you export as an MP3 file using the <span  style="background-color:#CCFFCC;color:#a0522d">File > Export As MP3</span> command, you can greatly reduce the size of the exported file. MP3 loses some audio quality, but if you export your MP3 at Audacity's preset MP3 export bitrate of 128 kbps, this gives very reasonable sound quality for about 1 MB of space per minute. You can compress the MP3 to a still smaller file (at the cost of further quality loss) if you go to the <span  style="background-color:#CCFFCC; color:#a0522d"> File Formats tab of Preferences</span> and reduce the MP3 Export bitrate at "MP3 Export Setup". Click the downward pointing arrow in the Bit Rate dropdown as shown below, choose a lower bitrate from the list, and click OK:

For example, if you chose 64 kbps, your exported MP3 would take up 0.5 MB (500 kb) per minute, because 64 kbps is half the bitrate of 128 kbps.

|'''HINT:''' If you want to export MP3s you need to add the LAME encoder to your computer. Instructions for doing this are at [[Lame Installation]].
Note that you should always attach your audio file to the email message. Some email clients can embed the audio inside HTML email messages so that the recipient hears the audio on opening the email without having to open an attachment. However whether the recipient will hear the audio depends on the recipient having an
HTML email client (or having HTML enabled without any security restrictions in place). Many email users disable HTML email due to the perceived security risk of HTML email.
Note also that sending files greater than 5 MB by email is usually out of the question due to server bandwidth and storage restrictions. Some webmail services such as GMail do allow files up to 10 MB to be transferred. The solution is to use a web-based transfer service like {{external|[http://www.yousendit.com yousendit.com]}} or burn the exported audio file on to an audio CD and send it by postal mail. If you want to burn to an audio CD you need to export 44 100 Hz, 16 bit stereo WAV or AIFF files, and tell your burning software to burn an "audio" or "music" CD. For innstructions on how to do this, see [[How to burn CDs]].
Audio CDs will retain the full quality of the original track in Audacity, can contain 74 – 80 minutes of music and can be played in computers and on any standalone CD player (and some standalone DVD players).
