read/write optimization

[orbs]

following my last post on this thread:

'?do=embed' frameborder='0' data-embedContent>>

until native FileCopy supports EFS, i scribbled a very simple alternative:

Func MelmacFileCopy($sSrcFile,$sDstFile)
    Local $hFile,$sFileContent

    $hFile=FileOpen($sSrcFile,16)
    $sFileContent=FileRead($hFile)
    FileClose($hFile)

    $hFile=FileOpen($sDstFile,16+2)
    Local $result=FileWrite($hFile,$sFileContent)
    FileClose($hFile)

    Return $result
EndFunc

it basically reads the entire file into memory, then writes it into a new file.

i'm in progress of improving the functionality in several ways, like creating destination folder if it does not exists, better error control, etc.

i ask the forum assistance for ways to optimize the performance of this function. should i read the entire file into memory, or in parts? if yes, then what size those parts should be? i use Binary format to make it compatible to whatever format the file may be in, is this correct or is this the most effective way? etc.

any ideas are welcome. thanks all.

Hi,

You can still make your own tests using the TimerInit/TimerDiff functions to compare them.

Br, FireFox.
