"""
|
|
Script to copy Atari files with (potentially) too long names from
|
|
source directory into target directory, using in latter file names
|
|
clipped to 8+3 characters.
|
|
|
|
Clipping is done like Atari GEMDOS functions would do it, so that
|
|
those file names can then be moved/copied to Atari media from another
|
|
OS.
|
|
|
|
If original long names work with Hatari GEMDOS HD emulation, the
|
|
clipped names should work with normal TOS on real harddisk (image)!
