Unraid is a popular operating system designed for network-attached storage (NAS) and server applications. It provides an intuitive interface and robust capabilities for managing data. However, you may find yourself in a situation where you need to delete all files on your Unraid server, either for maintenance purposes or to clear space. In this article, we'll explore how to delete all files on Unraid, provide insights from the community, and offer some additional best practices to ensure your data management is efficient and secure.

Why Delete All Files on Unraid?

Before diving into the deletion process, it’s essential to understand why you might need to delete all files. Common scenarios include:

Server Cleanup: You may want to remove unnecessary files to free up space.
Data Migration: If you are transitioning to a new system or server, you might need to delete existing files.
Error Recovery: Sometimes, files may become corrupted or problematic, necessitating a fresh start.

How to Delete All Files on Unraid

Using the Unraid Web GUI

Log In: Access the Unraid web interface.
Navigate to Shares: Click on the ‘Shares’ tab on the top menu to view your shared folders.
Select the Share: Identify the share you want to delete files from and click on it.
Click on "View": This will show you all the files within the selected share.
Select All Files: Use the checkbox to select all files. Alternatively, if you want to delete everything in that share, you can perform a manual selection.
Delete: Click the delete option (usually represented by a trash bin icon). Confirm the deletion when prompted.

Command Line Interface (CLI)

For advanced users, using the command line provides more flexibility. Here’s how:

Access the Terminal: You can access the command line through SSH or by using the terminal in the Unraid GUI.
Identify the Share: Know the path of the share you want to delete files from. For example, /mnt/user/myShare.
Delete Files: To delete all files in a share, run the following command:
```
rm -rf /mnt/user/myShare/*
```
Note: This command will irreversibly delete all files in the specified directory, so use it with caution.

Important Considerations

Back Up Your Data: Always back up essential files before conducting massive deletions.
Permissions: Ensure you have the necessary permissions to delete files in the specified directory.
System Files: Be cautious not to delete system files or folders that Unraid uses for its operation.
