'            >> FileManager.bas <<
' adapted (ie. stolen & exended) from [main.bas] by me.
' Optimized for 600*636 w-s-kb (600*1024 wo-kb) tablet.
' Works fine for me on Android and Win
'
' Warning: Not heavily tested. If you like it, use it &
' adapt it to meet your needs. No waranties, anyway!
'
' Tip-1: if you have selected a file, AND a directory
'   is in the edit field, the file-operations affect
'   the "directory/file" relative pathname construct.
'
' Tip-2: I made /storage/sdcard0/external_sdcard/sb12/
'   directory as my "home directory" on Android.
'   If set, it is NOT allowed to "walk" outside "home".
'   If you set a "home directory", put this program
'   there, and edit next line accordingly.
