.zip file turned into .z file???

[Mean MrMustard]

I have a zipped program that I have on my old computer. I installed perfectly fine along time ago on that machine. Since then, I wanted to install it on my new machine. Suddenly it is a .z instead of .zip. Winzip won't decompress it because it doesn't recognize the "header." Everything was fine earlier until now. How do you change the file extension? Not just renaming it. Any suggestions are appreciated.

Go to the command prompt, and go in to the directory that the file is in. Type the following: ren *.z *.zip

That will "rename" all of the files in the directory with a .z extension to one with a .zip extension.

I really appreciate the synopsis. Rather than crapping on my contribution, what do you recommend?

I assumed he wanted the extension changed, which can be done at the command prompt. Files don't just change compression formats over time. If it happened to be compressed with GZip (.Z extension), WinZip should be able to handle it.

No reason to be offended - I just pointed out that he specifically said he did not want to know how to rename the files, which is exactly what you told him.
On a sidenote, I had read the post, too, and (same as you, obviously) did not know how to help him, because, as you correctly point out, files don't change their compression formats over time. I don't use WinZip anymore, and don't remember exactly how crappy it is, but I'm pretty sure if the files were of any format supported by it, WinZip would find out and extract them, ignoring the file extension (at least decent programs do that).
My impression is that the files are, for some unknown reason, defunct. But since I am no expert on using WinZip, that may very well be wrong, and is therefore not a reason to give up trying.
