# File Management
## Save Project
### Save
Click **Save Project** in the "File" menu to save the current project.
Shortcut key: Ctrl/⌘ Command + S
{% hint style="success" %}
Regularly save your work to prevent data loss. Make it a habit to use the save shortcut keys during your workflow.
{% endhint %}
### Save as
Click **Save as** in the "File" menu to save the project as a new file.
Shortcut key: Ctrl/⌘ Command+ Shift + S
### Auto save
During project startup, an automatic backup will be made every 10 seconds. The automatic backup will be cleared after a manual exit, but will be preserved in case of unexpected crashes. The ACE Studio will proactively ask if you want to open the backup project at the next launch.
Each time you save this project manually, a copy will be saved under this project folder “autosave”. This become a part of the project history, and you can restore a historic version from this folder.
### Collect all files and save
Click **Collect all files and save** in the "File" menu to copy all audio files from external sources used in the project into the "Samples" folder inside the project folder.
## Project File and Project Folder
The project will be saved as a folder in the specified directory, which includes:
* Project file \*.acep
* "autosave" folder containing automatic backups during project startup and the last 10 historical manually saved backups.
* “Samples” folder containing all audio files generated from this project.
* You can move the audio files under this folder. If the original audio file path is lost when the project is restarted, ACE Studio will automatically look for it in the project directory. This also helps when sharing the whole folder to others.
## Limits
* The max duration of a project is 40 mins.
* The max number of AI voices in a project is 60.
