Hi!
I must do read a file
the code is simple:


$filename = "D:\ter\TE.txt"

$timer = TimerInit()

$SuperMegaGigaFile = FileRead($filename)

MsgBox(0,"",Round(TimerDiff($timer)/1000))



The problem?
The file size of the file is: 460m
text file

To read a file that large you'd need roughly 2GB of RAM to run effectively. How much do you have? There are also threads on reading files by parts through buffers. Try one of those.

I have 2 gb
i try with buffer, the name of the function?
thanks

It's not just one function, it's a custom method. Just search the forum for "file buffer" or something similar. Also you need to realize the 2GB was a guess as to how much you would need, you may need more you may not need that much.

Here you got the UDF that dbzfanatic were talking about

All needed API functions for that are now included in standard AutoIt's UDF WinAPI

Here is example of use:
