I was talking about Windows Explorer, not File Manager, eidenk. If you copy a 2Gb file from within Explorer (not File Manager or any other app) in WinME, it will copy ok without WinME kernel patch. Excuse me please, but you said it didn't make sense to patch the WinME kernel32.dll at all : Additionally I was not answering to you specifically and what you now explain to me I know it well enough already if you want to read the few posts I made in this thread.
