Nadya:
If you have other questions, I'll try to answer them. I spent last week working up a backup, restore and partial restore (which should NEVER be used). DZPROG32.exe is provided with DynaZip to allow you to display a progressbar and Cancel button. I printed out Chapters 5 & 6 and read them first. Took their dzexvfp project from the samples directory and used the code to understand how to make everything work.
