note 70687 added to function.is-dir

I'm not sure what is going on here... I have a function to return a listing of (sub)directories within a directory. Works great until I ran into the directory given in the warning below... 87 characters seems too short to be running into a file/directory name length issue? This is what I'm getting (though broken into a couple lines so this forum will accept it): Warning: is_dir(): Stat failed for /home/office/public_html/Library/1_NNHP-produced/4_Maps /Peterson2003/BRTEreport_DVD.zip (errno=75 - Value too large for defined data type) in /home/office/public_html/index.php on line 104 Here is line 104: if (is_dir($dir .
