What to do when I click to open my zip file and encounter an error, the zip file is invalid?
Sometimes due to certain viruses in the device, security issues related to MS office, or if the file being downloaded is corrupted, the screen pops up with an error i.e. zip file is invalid.
A file having Zip format is an extension file that is a compressed form of data and is widely used all over to store information. It is like all other available file formats, a collection of one or many file folders that are compressed into one to give it ease of transportation and compression.
