I assume that this is what you want. You want a filename field on the selection screen. When the user wants F4 value help - you want a file open dialog to help them find their files. The following should do just that.
----
SELECTION-SCREEN *
----
parameter: ifile type file_table-filename obligatory.
----
SELECTION SCREEN - VALUE REQUES FOR FILENAME *
----
at selection-screen
on value-request for ifile.
data: window_title type string.
data: path type string.
data: filename type string.
data: fullpath type string.
move 'Source Data File'(001) to window_title.
call method cl_gui_frontend_services=>file_save_dialog
exporting
window_title = window_title
changing
filename = filename
path = path
fullpath = fullpath
exceptions
cntl_error = 1
error_no_gui = 2
others = 3.
if sy-subrc <> 0.
else.
move fullpath to ifile.
endif.
This would do a file-save dialog. If you want a file-open dialog the following example would work:
----
SELECTION SCREEN - VALUE REQUES FOR FILENAME
----
at selection-screen
on value-request for ofile.
data: window_title type string.
move 'Destination Data File'(002) to window_title.
call method cl_gui_frontend_services=>file_open_dialog
exporting
window_title = window_title
DEFAULT_EXTENSION =
DEFAULT_FILENAME =
FILE_FILTER =
INITIAL_DIRECTORY =
MULTISELECTION =
changing
file_table = ifile_tab
rc = rc
USER_ACTION =
exceptions
file_open_dialog_failed = 1
cntl_error = 2
error_no_gui = 3
others = 4.
if sy-subrc <> 0 or rc < 1.
else.
loop at ifile_tab into ifile_tab_line.
move ifile_tab_line-filename to ifile.
endloop.
endif.

No problem. What you need is in the same class, CL_GUI_FRONTEND_SERVICES, but a different method: DIRECTORY_BROWSE. It works very similar and does exactly what I believe you want it to do.

By UNIX I assume that you mean directories on your SAP application server. I don't know of anything quite as nice as what is available for the front-end tools. However you might want to check out the function module EPS_GET_DIRECTORY_LISTING and other function modules in the same function group. By default this only returns files. I copied the function module and made a few changes to return both files and directories. With this you could code a pop-up of your own. I also made some of the variables for files and directories larger. The following is my copy of EPS_GET_DIRECTORY_LISTING from a 46C system.
function z_e_get_directory_listing.
