Where Audacity stores temporary files and why you might move them

Audacity stores temporary files in a default folder on your computer while you work on audio projects. These files can grow large quickly, especially if you're editing long recordings or working with multiple tracks. If your main drive is running low on space, or if you want those temporary files on a faster drive, you can tell Audacity to use a different folder instead.

The temporary directory holds the audio data Audacity needs to undo changes, play back your project, and save your work. Moving this folder to a drive with more free space or faster performance can make Audacity run more smoothly and prevent your main drive from filling up.

Key Takeaways

  • Audacity's temporary files live in a default system folder that you can change through the Preferences menu.
  • You can point Audacity to any folder on your computer, including external drives or secondary hard drives.
  • The new temporary directory must exist before you change the setting — Audacity will not create it for you.
  • Changing this setting takes effect the next time you launch Audacity, and does not affect projects you have already saved.

How to find and open Audacity's Preferences

On Windows, open Audacity and click the menu button (three horizontal lines) in the top left corner. Select Preferences from the dropdown. On Mac, click Audacity in the menu bar at the top of the screen, then select Preferences.

The Preferences window will open. You will see a list of categories on the left side. Look for Directories in that list and click it.

Locating the Temporary Files setting

Once you are in the Directories section, you will see several folder paths listed. Find the one labeled Temporary Files. Next to it is a folder icon and a text field showing the current location of your temporary directory.

The default location varies by operating system. On Windows, it is usually inside your user folder under AppData. On Mac, it is typically in a hidden Library folder. You do not need to remember or find this folder — you only need to know where you want the new one to be.

Creating a new temporary files folder

Before you change the setting in Audacity, create a new folder on the drive where you want temporary files to go. Right-click on your desktop or open File Explorer (Windows) or Finder (Mac), navigate to the drive you want to use, and create a new folder. Name it something clear like "Audacity Temp" or "Audacity Temporary Files".

Make sure the folder is completely empty and that you have write permission to it. Audacity needs to be able to create and delete files inside this folder without restrictions. If you are using an external drive, make sure it is connected and formatted in a way your computer recognizes (NTFS or exFAT for Windows, APFS or Mac OS Extended for Mac).

Changing the temporary directory path in Audacity

Back in the Directories section of Preferences, click the folder icon next to the Temporary Files field. A file browser window will open. Navigate to the new folder you just created and select it. Click Open or Choose (the button name depends on your operating system).

The path to your new folder will now appear in the Temporary Files field. Click OK at the bottom of the Preferences window to save the change. Audacity will confirm the new location and close the Preferences window.

What happens after you change the setting

The new temporary directory takes effect the next time you launch Audacity. Close and reopen the program to start using the new location. Any projects you have already saved are not affected — this change only controls where new temporary files go while you are actively working.

You can safely delete the old temporary files folder once you have confirmed Audacity is working properly with the new location. The old folder will not be used anymore, and clearing it out frees up space on your original drive. If you ever want to move temporary files again, follow the same steps and point Audacity to a different folder.

Troubleshooting if Audacity will not accept the folder

If Audacity shows an error or will not save your preference change, the most common reason is that the folder does not exist yet. Go back and create the folder manually before trying again. Another possibility is that Audacity does not have permission to write to that location — this can happen with system folders or folders on network drives.

If you are using an external drive, make sure it is connected and visible on your computer before you select it in Audacity. If the drive disconnects later, Audacity may not be able to write temporary files and will show an error when you try to record or edit. In that case, change the temporary directory back to a folder on your main drive.

Frequently Asked Questions

Can I use an external USB drive for temporary files?

Yes, but only if the drive is connected when you use Audacity. If the drive disconnects or is removed, Audacity will not be able to save temporary files and will show an error. For reliability, use a secondary internal hard drive or a fast external drive that stays connected.

What happens to temporary files when I close a project?

Audacity deletes temporary files when you close a project or exit the program. These files are not meant to be permanent — they exist only while you are working. If you want to keep your work, save the project as an Audacity file (.aup3) or export it as an audio file.

Will moving temporary files make Audacity faster?

It can, if you move them to a faster drive. If your main drive is slow or nearly full, moving temporary files to a faster secondary drive or SSD may improve performance. Moving them to a slower drive will have the opposite effect.

Do I need to move temporary files if I have plenty of disk space?

No. If your main drive has several gigabytes of free space, there is no practical reason to move temporary files. The default location works fine for most users. Only change it if you are running low on space or want to use a faster drive.
