How to open wps files

Hello,
I recently bought a new PC and had documents from old PC transferred to new machine. I cannot open the wps files that were transferred. I get message
'Adobe Reader could not open file because it is either not a supported file type or because the file has been damaged'.
This is the reply from all transferred wps files - other types seem OK.
I have downloaded Microsoft office Word Viever without success - what else can I do please?
