How Do I Delete a File in MATLAB?

Deleting a file in MATLAB is a straightforward process, achievable through both the graphical user interface (GUI) and command-line methods.

Deleting Files Using the Current Folder Browser

One of the easiest ways to delete a file directly within the MATLAB environment is by using the Current Folder browser. This method is intuitive and familiar to users accustomed to graphical interfaces.

Here's how to do it:

• In the Current Folder browser, locate the file or folder you wish to remove.
• Select the file or folder by clicking on it.
• Press the Delete key on your keyboard.

As mentioned in the reference, By default, MATLAB deletes or recycles files and folders according to your operating system preferences. This means that depending on your OS settings, the file might be permanently deleted or moved to your system's Recycle Bin or Trash.

Deleting Files Using the Command Line

For users who prefer working with commands or need to delete files programmatically, MATLAB provides the delete function. This method is particularly useful for scripting and automating file management tasks.

Syntax:

delete(filename)

• filename: A string or character array specifying the name of the file to delete. You can include the full path if the file is not in the current folder.
• You can also use wildcards (*) to delete multiple files that match a pattern. For example, delete('temp_*.mat') deletes all .mat files starting with temp_ in the current folder.

Examples:

• To delete a single file named mydata.txt in the current folder:

  delete('mydata.txt')

• To delete a file located in a specific path:

  delete('C:\Users\YourName\Documents\MATLAB\reports\report.pdf')

• To delete all files with the .log extension in the current folder:

  delete('*.log')

Important Considerations:

• Using the delete function typically bypasses the Recycle Bin/Trash and permanently removes the file. Use with caution!
• Ensure you have the necessary permissions to delete the file.
• If the file is currently open or in use by another program (including MATLAB itself), the delete command might fail.

Whether you choose the graphical approach via the Current Folder browser or the command-line method using the delete function, MATLAB provides simple ways to manage your files effectively.
