Well, first of all i want to apologise for my poor english. My problem is that I have problems accessing net mounts on windows. For example, if R: is a unit attatched from the internal net and I try to access it, I get error. The following code is what I'm trying to do to test the access: -------------------------------------------------------------------------------------------------- echo "<a href='" . $filename2 . "'> arxiu </a><br>"; if($error=basename($filename2)) echo $error . ": basename<br>"; else echo $error . ": basename<br>"; if($error=disk_free_space('G:')) echo $error . " G: free space<br>"; else echo $error . " G: There isn't free space<br>"; if($error=copy($filename2,'.')) echo "Copy successfull<br>"; else echo $error . " Copy successless<br>"; if($error=is_readable($filename2)) echo "Read successfull<br>"; else echo $error . ": The file cannot be readed<br>"; if($error=file_exists($filename2)) echo "File Exists<br>"; else echo $error . ": The file doesn't exists<br>"; ------------------------------------------------------------------------------------ -------------- $filename2 is the path to a file in a net mount. and the output is: ------------------------------------------------------------ loss_of_supervision: basename G: There isn't free space Copy successless : The file cannot be readed : The file doesn't exists ------------------------------------------------------------ I try the same code with C: unit and a file inside it and works fine... There's some kind of bug or it's my server's configuration that is wrong?
