The delete-file BASIC program releases all frames used by the specified file to the overflow table, and removes the file reference from the master dictionary of the current account.
Synonym-defining items (Q-pointers) cannot be deleted with this command. The account must possess the actual D-pointer to a file to be able to delete the file.

| option | i | Cancels the delete if a file is open when the delete-file attempt takes place. The system displays file still open, delete canceled. Control returns to TCL or a calling program without prompting for input. |
| u | Deletes the file unconditionally, even if it is open at the time of the delete. |
The dictionary level cannot be deleted without first deleting any data sections that it may have pointers to.
If another user is still using the file, this command prints a warning message and asks if the user wishes to continue. If the delete is allowed to continue and another user is actively using the file, then the other user may abort and/or experience workspace corruption. Delete shared files with caution.
