Once you have created a Local Drive filter, you can modify it as desired in the Editor for Local Drive Filter Files. For details on creating a Local Drive filter, see "Create a Local Drive Filter".

7. Save filter file: Click OK. The filter file is saved and can now be allocated. For details on allocation of a Local Drive filter, see "Allocate a Local Drive Filter".
