Finding the file name with Regular Expression

Question

Hello All,
I am having some requirment to find the file name for the input provided parameter.
In my program i am having an input parameter for file name. This contains both the file name and file stored location.
Example : C:\Dokumente und Einstellungen\xs234fs\Desktop\TEST_123_44.txt
From the above example string i need to find only the file name that is TEST_123_44.txt by using Regular expression.
Please let me know how to get this.
Thank you ver much in advance.
Thanks,
Feroz.

Hello,
If you have attached an F4 help to the filename input param, in that you can use the FM: GUI_FILE_SAVE_DIALOG.
In this there is a return param FILENAME which contains the name of the file.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_FILE.
      CALL FUNCTION 'GUI_FILE_SAVE_DIALOG'
       EXPORTING
         window_title            = TEXT-001
         default_extension       = p_extens
         default_file_name       = ls_deffile
         initial_directory       = ls_initdet
       IMPORTING
         filename                = ls_filename "This contains the filemame
         path                    = ls_path
         fullpath                = ls_fullpath
         user_action             = ls_usaction.
Else if you have hardcoded the filename in the input field you can use rthe FM: PC_SPLIT_COMPLETE_FILENAME to split the filenames into different components
