Most of the file that I had been using for my work and personal use, I do use the Microsoft word processing documents software which uses the file extension DOC. Where you will be needing to use a file extension wps to be sure that you can edit, create and save a specific file on a specific software that you are using.
The file extension wps which is the file extension of documents saved that you can use with the Microsoft Works. The Works which is like a bare-bones version of Word, as you can see you may find it lacking many of its features but still many of us especially like me who still uses it for it is still capable of producing text documents. You can use the program file extension wps usually which was installed on most PCs running Windows operating systems. The Windows users have to purchase Microsoft Word separately, but Works comes preinstalled. To find the file extension have a visit the link on my post and find the right site which can give you not just the information that you needed but also the free download for it.
