Original GitHub issue: https://github.com/prasathmani/tinyfilemanager/issues/127

I have a couple of files over 2GB in size and they are displayed with negative size.
After reading some sources, turned out filesize() doesn't work well with 32-bit system for files bigger than 2GB.

I found some functions to replace filesize() that will work, but I am not sure if it is a good idea for me to edit the code by myself. Maybe you know the best method to use.

Thanks.

Hi. Looking into the commit, you just added support for Windows but Linux will still be using filesize.

function fm_get_size($file)
{
    $return = filesize($file);
    if(substr(PHP_OS, 0, 3) == "WIN") {
        exec('for %I in ("'.$file.'") do @echo %~zI', $output);
        $return = $output[0];
    }
    return $return;
}

The code clearly would just be checking for a Windows and use specific method, but then if Linux, it would still be using filesize().

I have tried searching a solution by myself and found this solution works: https://stackoverflow.com/a/5502328
