Hi, I am using windows vista and if I am going to unzipp a file that zipped throug php code, it says file corrupt! But if the file is too small like 1 or 2 lines it open ,if more than 2 lines it does not open. Don't understand why?? anyone can help or share any idea. Trying to unzip in windows vista. $zip = new ZipArchive; if ($zip->open('test.zip' ,ZipArchive: :CREATE) === TRUE) { $zip->addFile('/path/ to/index. txt', 'newname.txt' ); $zip->close(); echo 'ok'; } else { echo 'failed'; } kabir [Non-text portions of this message have been removed]
