Hey Everyone,

I trust you are all well and keeping safe. Can you please advise me on what is the best Repair zip tool to open an corrupted archive that was compressed using WinZip, I have these old project files that I need to access urgently in Windows 10, I have downloaded 7zip but it is still giving me errors it is now coming up with an error message "cannot open the file as 7z archive is not archive" , and obviously I can not redownload the files....! I have read the 7zip help menu, but I am not good at command language. I have seen quite a few repair tools out there such as (Zip repair, Object fix, Yodot) but not sure which is good, so this is why I need your help urgently.

Many thanks in advance

Are you sure that your ZIP file is actually a ZIP file? Try opening the file in a text editor and check if the first two characters in the file are PK. If not, it's not a ZIP file.

Hey JDMurray

Thanks for responding, I am very sure I zipped up several files using Winzip,I have managed to open some folders using 7zip but this particular file in question is 55mbg.
Thanks Cassma

It would be good to verify if what you have is a PKZIP file or not. Sometimes a file gets transformed into another data format for whatever reason or even stripped of its binary content. 55MB is a small file that a modern text editor can handle.

Do you have access to the original files in an unzipped form?
