Re: Cannot open zips they are either invalid or corrupt

I have never heard of a zip that comes in parts like a rar does.. I'm up for learning anytime.. and in this particular zip was one file, a graphic.. one image! You are right, I was talking about a cam zip utitlity.. had 7zip on my mind.. lol thanks for all the information.. had trouble with the 7zip and file association.. I had so many unzip utilities on my computer, I had to uninstall the ones I wasn't going to use... then went to folder options to make sure zips were associated with 7zip. It wasn't! . Thanks for wading through my explanation.. I appreciate the input and all the new information.. and No I didn't know this.. I have had a computer for 10 years or more and have never seen a zip that depends on other parts of the zip like a rar does.. Is that what you mean by Multipart? hugs rainy

every time I try to unzip a zip file using either winzip,

Unzip which is now telling me I only have one part of the zip. like
a rar that comes in parts.. ? (It's only one zip) I would
appreciate knowing how to fix this one.. I have been searching for
an answer for a few weeks.. so far all I have found is a suggestion
to go to Tools Folder Options, File types, click on the unzipping
utitlity, advanced and make sure that confirm open after dowload
has a check mark..it already had a checkmark, so now I don't know
what to do. .. I am thinking it's a registry problem.. but don't know how to fix or where to start. I
just installed 7zip and still it does the same thing. Yesterday I repaired the
operating system, thinking that might fix the problem.. :( Would
appreciate
some advice please...

You can have a multipart zip. You should know this - 7-Zip can do it.

7z, ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, ISO, MSI, WIM, NSIS, RPM and DEB are all just compression algorithms essentially. Different ways of doing the same thing - essentially making a file/set of files smaller by getting rid of 'empty' space. The multi-part compressed file is more a feature of the application in some ways than the algorithm you have chosen. It was done legitimately for some so that they could spread the results across multiple (usually smaller) external media sources *and* the software 'sharing' community liked it because it allowed for checksums easily and made the download sizes smaller (in batches) and a bunch of smaller single files (compressed) is less to download overall. With high-speed Internet more common, this is not done quite as much.

What is confusing (and the real reason for the response) about your solution...

First post:
"I just installed 7zip and still it does the same thing."

Post with supposed solution:
"[I] downloaded 7zip and it worked."

Now - I understand (although it is a bit confusing and mentioned almost as a "and oh yeah...") that you later state, "I also downloaded a corrupted zip repair utitlity called Object Fix and it repaired the corrupted zip." --> something I think you might have said first thing. ;-) Skimming the results might lead someone to quickly believe you had a corrupt 7-Zip install and somehow had a messed up native compression utility as well. ;-)
