I received the following E-mail from the programers of PIEPlus.
Thank you for contacting us.
PIEPlus does not use temporary files. If you get a loss of storage
space, it may be caused by memory leakage of PIEPlus.
I'm sorry for the problem and we'll try to solve this issue and update
next version.
Best regards,
