Any unsaved application data will not be saved once an application was forced to quit. Do it only if necessary.
When to force quit an application? Only when its unresponsive and cannot be quit in a usual manner.
I bought a macbook last december 2009 and transfer my files from my windows laptop. After the the transfer, the first thing I did is to browse the projects that I’ve done. While browsing, I came across a page where in there is a file upload facility. Then I started to upload a file. While uploading, it suddenly popped an error. Then I checked the folder I used to put the file uploads and found out the file is not there. What could be the solution? It’s the upload_tmp_dir found in the php.ini. Just make sure that the folder path where you put the uploaded file is specified.
