Have a problem opening a .ZIP file? We collect information about file formats and can explain what ZIP files are. Additionally we recommend software suitable for opening or converting such files.
What is the .ZIP file type?
The ZIP file format is a popular archiving format used to combine, encrypt and store files in a single data container. This packaging system helps reduce the total size of the files when necessary - for example, if you need to free up some disk space or send large files via email.
The ZIP file format was originally created by Phil Katz for the PKZIP file archiving software in 1989 and is still considered to be the most popular type of archive formats. It is used by numerous applications, but they may add extensions other than .zip to their files.
A zipped archive can store just one or multiple files in several directories. It allows users to download and distribute a group of files at once. The inside content can be compressed with the help of various packaging methods - or even not compressed at all.
If you downloaded a zipped file that you need to open, you can use compression/decompression programs built into your operating system, or you can take advantage of third-party utilities capable of unpacking .zip archives.
