How to Fix Corrupt Zip File?


If you download and upload a lot of files over the internet, you must be familiar with the Zip files. Zip files are compressed or achieved files that contain any data in its compressed form. A Zip file can hold any number of files and folders of any file formats into a single Zip file with file extension of .zip. This is a great invention as Zipping a file has many benefits where storing, transferring or downloading multiple files are concerned. Main advantages of a Zip file over any normal file are: Zip file occupies less space as it is in a compressed form; storing large number of multiple files is easier when all the data is in a single Zip file. A Zip file is safer and can be secured with a password or encrypted. Obviously as Zip files consumes less space, they can be downloaded or uploaded with ease.

How does a Zip file work? Any special software such as WinZip is used to bundle all files and folders in to a single Zip file with .zip file extension using a technique called Lossless Compression technique- meaning all data can be restored to its original size once it is unzipped. A Zip file can sometimes be compressed up to 90% of its original file size.
