What can ZIP files do?
ZIP is a special file format for compressed data. ZIP files have the extension ".zip", text files, for example, have the file extension ".txt".
- A ZIP file has two major advantages: ZIP files serve as containers and can therefore combine numerous other files and folders in one file. For example, you can pack and send multiple documents, images and folders in just one file.
- On the other hand, the data is significantly reduced by packaging it in a ZIP file. Depending on the size of the file, several percent of the original file size can be saved. For example, a 4.5 GB film in a ZIP file can easily become a 4 GB film.
- With programs like 7-Zip or WinZip you can open, create and edit your own ZIP files. You do not need any additional software to open a ZIP file. Windows can open and extract ZIP files by default.
