Problem with listing filesize bigger than 4GB

kumschick

problem with file listing.
There is a bug with listing the file size.

If the file is bigger then 4GB that it's showing strange file size.

File is 7,56GB but only showing 3,13GB ???
On php.net they say to just this formula!

$myfilesize = sprintf("%u", filesize("c:/xx/xx/xx.xx"));
echo"<p>$myfilesize</p>";

if($myfilesize >= 1073741824) {
  $myyfilesize = number_format($myfilesize/1073741824,2,',','\'');
  $myxfilesize = "$myyfilesize GB";
}
else {
  ...
  ...
}
...
...

I'm not clear on what you're problem actually is. Are you just reporting the fact that filesize() returns unreliable values for file sizes larger than 4GB? Or are you looking for a method of obtaining such file sizes, where the various suggestions in the user notes on the [man]filesize[/man] page (where, incidentally, I don't find the code you list) aren't usable?

(I went to try the shell suggestion out, but I coulnd't find a >4GB file on my system to test it. But when I generated one and tried the shell command method suggested in one of the users' notes, it worked. I'm assuming from your code you're using a Windows system: dir works with a wee bit of parsing. I'm also assuming you're using an NTFS filesystem, or 4GB files wouldn't even be an issue.)

I wrote an special administration that gives you access to ALL files on the server. c: ; d: , e: , etc...

as if you would be in "Windows Explorer"

And on that server I have files bigger than 10GB.
And I want to know to to obtain the correct filesize.

I'm using PHP 5.0.1.

Thx

Yes, we use a rack server running windows 2003 enterprise edition with NTSF SCSI hdd. We have total of 10TB (10'000G😎 and very very big files. But I need the correct filesize.

you don't have any idear how to fix this isue?

thx

Well, filesize() is no good, because it only returns an int, and the size of those files won't fit in an int. Further, to manipulate them, you'll want to use the bcmath functions - like [man]bcadd[/man] (the alternative would be to use doubles and risk losing precision).

To get the sizes, I found that
