Problems with files using the .7z extension?

[Theees]

Before a certain date, I was able to open files with the .7z file easily, without the 7zip or WinZip programs. After some time, for some reason the .7z extension was automatically opened from the Notepad program, and I was unable to remember how I had opened it before. I was wondering if there was any way to open 7zip files without the two programs listed above?

(Thanks for any help)

When you download a file with .7z.

Right click on it and choose open with.

Click on the choose default program option in the pull down menu.
Click on other programs see if winzip in in there.

Or click on browse.

Find winzip and select it from the list of programs to open with.
Click ok or apply.

You need to associate the .7z file extention to winzip.
