problem cl_gui_frontend_services=>execute when folder has space

Hi Experts,

I use "execute method" in "cl_gui_frontend_services class" for encrypting my text file. it is working when folder does not have space

lv_param = 'C:\Users\myname\Desktop\PA\File.txt'.
lv_default = 'C:\Users\myname\Desktop\PA\'.

CALL METHOD cl_gui_frontend_services=>execute 
     EXPORTING 
        application = 'C:\EncryptFile.jar' 
        parameter = lv_param 
        default_directory = lv_default 
        maximized = 'X' 
      EXCEPTIONS 
        cntl_error = 1 
        error_no_gui = 2 
        bad_parameter = 3 
        file_not_found = 4 
        path_not_found = 5 
        file_extension_unknown = 6 
        error_execute_failed = 7 
        synchronous_failed = 8 
        not_supported_by_gui = 9 
        OTHERS = 10.

This code is working.

If My folder has space as code below ('C:\Users\myname\Desktop\P A\File.txt'). It is not working

There is space between "P" and "A"

lv_param = 'C:\Users\myname\Desktop\P A\File.txt'.
lv_default = 'C:\Users\myname\Desktop\P A\'.

CALL METHOD cl_gui_frontend_services=>execute 
     EXPORTING 
        application = 'C:\EncryptFile.jar' 
        parameter = lv_param 
        default_directory = lv_default 
        maximized = 'X' 
      EXCEPTIONS 
        cntl_error = 1 
        error_no_gui = 2 
        bad_parameter = 3 
        file_not_found = 4 
        path_not_found = 5 
        file_extension_unknown = 6 
        error_execute_failed = 7 
        synchronous_failed = 8 
        not_supported_by_gui = 9 
        OTHERS = 10.

What can I do for solving this problem when my folder has space?
