Office documents converted to win rar files


#1

I restored my files with WD my book and I had a cookbook that I worked on for 8 years that restored in a winrar file.  I found winrar and downloaded it.  I try to open my document with it and it says files damaged.  I would like to either restore them to their original format or get them opened in this winrar (whatever that is ) Can anyone help me restore this document?
