How to Delete a File With MATLAB


MATLAB uses files to store numeric and graphical results, and MATLAB functions and code may be contained in files as well. Delete files in the default file path -- the "MATLAB" folder in your user "Documents" directory in a typical Windows installation -- or elsewhere using the "delete" command, or with the file browser in the MATLAB desktop.

  • Launch MATLAB and choose a file to delete. To quickly create a new file to work with, type the following command into the Command Window:

    save testfile.m

  • Use the "delete" command to delete a file programmatically:

    delete testfile.m

    Specify the whole path of the file (e.g.,"C:...") if it isn't in the MATLAB default path. Delete multiple files using the following syntax:


  • Right-click a file in the "Current Directory" browser and choose "Delete" from the drop-down menu to delete the file using the MATLAB interface.

Tips & Warnings

  • Use the asterisk as a wild-card character to delete many files at once. For example, to delete several files whose names start with "testfile," use the following command:
  • delete testfile*
