Founded. Thanks if somebody tried to help.

Delete range from 10 to 20:

        FileOpen $0 "C:\File.txt" a
        FileSeek $0 0 END $1
        IntOp $2 $1 - 20
        System::Alloc $2
        Pop $3

        FileSeek $0 20 SET
        System::Call 'kernel32::ReadFile(i r0, i r3, i $2, t.,)'
        FileSeek $0 10 SET
        System::Call 'kernel32::WriteFile(i r0, i r3, i $2, t.,)'
        System::Call 'kernel32::SetEndOfFile(i r0)'

        System::Free $3
        FileClose $0
