Q: When I try to save a file in PDF Studio, it gives me an error message saying that “The process can not access the file because it is being used by another process”. I am using Windows 7.

A: Under Windows Vista and Windows 7, if you’re using the Preview Pane in Windows Explorer, any PDF file being previewed is locked by the preview process for an extended period of time. So if you open the file in PDF Studio when the file is being previewed or within the locking period, you will be unable to save the file.

You can use “Save As” to save to another file as a workaround.

To stop the issue from happening, you can turn off the preview pane.
