How LUA copies binary files

Using LUA to copy binary files is a bit more complicated than a text file, as follows

function Copyfunc (Targetpath,sourcepath)

Local RF = Io.open (SourcePath, "RB")--using "RB" to open binary files, if "R" is the case, is opened using the text mode, when encountered ' 0 ' will end the read

Local len = Rf:seek ("End")--Get file length

Rf:seek ("set", 0)--re-set the location of the file index to 0

Local data = Rf:read (len)--read file data based on file length

Local WF = Io.open (TargetPath, "WB")--writing binary files with "WB" method

Wf:write (Data,len)

Rf:close ()

Wf:close ()

End
