# Languages
## Managing Languages
Each language used in a Fuse application has its own language tab in the Audio manager. The name of the language automatically populates the tab title, e.g. English (U.S.A).
### **1. Default Language**
Users set the default language when creating a new application. The default language cannot be deleted.
### **2. Add a Language**
To add an additional language(s) to a Fuse application, click on the 
button next to the language tab. This generates a pop-up window with a drop-down menu. Select the desired language from the list provided.
This creates a new tab for that language. Fuse automatically copies the prompts from the default language to the new language. There is no need to construct a new call-flow for each language.
Use the [Language](/fuse/input/language.md) (
) module to allow end-users to select their preferred language on a call. Adding a new language in the audio manager will automatically update the available language options in the Language () module.
### **3. Delete a Language**
To delete a language from a Fuse application, position the cursor over the language tab and a small gear (
) icon appears in the upper right-hand corner of the tab. Clicking on the gear () icon gives users the option to delete a language from their application.
It is not possible to delete the default language.
{% hint style="warning" %}
Deleting a language permanently removes all of the prompts and pre-recorded audio for that language.

## **Download ZIP**
Click the 
button to download a ZIP file that contains audio files of all the audio files for that application.
## **Upload ZIP**
Click the 
button to upload a ZIP file that contains audio files of all the audio files for that application.
Users can update one or more audio files for a specific language using the Upload ZIP feature.
{% hint style="warning" %}
**Note**: When changing audio files, Fuse only overwrites the audio files in the ZIP file; it does not overwrite *all* the files for that language. \
\
For example, if an application has 10 English prompts with pre-recorded audio and a user wants to update two of the prompts, they can record new prompts, name them properly, and upload them in a ZIP file. \
\
Fuse will overwrite the audio files for those two prompts, but not the other 8 in the application. Each additional language must be updated separately.
{% endhint %}
## **Export CSV**
Click the 
button to download a CSV file that contains the filename and prompt text for each prompt in the application. Exported CSV files contain information for one language at a time. If users want a CSV file for each language in their application they must download each one individually.
