A family of Microsoft word processing software products for creating web, email, and print documents.
This is my understanding, which may not be correct.
The files that are saved in C:\Users\prg13\AppData\Roaming\Microsoft\Word is the last AutoRecovered version of a file if you close it without saving.
The files that are in C:\Users\prg13\AppData\Local\Microsoft\Office\UnsavedFiles is the document as it was when you closed it without saving it and may contain more that the AutoRecover version that could have been saved up to the number of minutes selected in the "Save AutoRecover information every # minutes" facility under File>Options>Save.
