How to tackle The Compressed Folder is invalid.. Zip error message

WinZip is a popular compression application used to compress one or more files into a single container file. It creates a .zip file and is also needed to open or unzip the files from the zipped folder. But, like every other computer application, WinZip also has certain flaws. At times, you may face some issues while opening the compressed or zipped folder, which indicates corruption of the zipped folder. Few reasons behind its corruption could be virus, improper system shutdown, power failure, and more. Zip file corruption causes inaccessibility of data stored in it. But, you can still retrieve your data in the presence of a data backup file. However, if the backup is not present, then you will need to repair zip file using a third-party application.

"You are about to activate an embedded object that may contain viruses or be otherwise harmful to your computer. It is important to be certain that it is from a trustworthy source. Do you want to continue?"
