What is a JZ file?

JZ files mostly belong to 7-Zip. The JZ file is a container for compressed data that can use different internal formats.

If the file stores a compressed JPEG image, it works much like the images seen in mobile galleries such as OnePlus Gallery.

If it contains an MP4 video, it acts as a compressed video container similar to files processed by YouCut.

If it holds a GZIP compressed JSON file, it wraps textual data in a compressed package—this variant is often managed with tools like 7-Zip. For more information about such compression, see the 7-Zip website.

How to open JZ files

You need a suitable software like 7-Zip to open a JZ file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your JZ file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JZ file directly in the browser:. Just drag the file onto this browser window and drop it.

JZ format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below is our analysis of the JZ files:

JZ is seldom used as a file extension and is used by a few programs, each with its own file format. However, the following two file formats are common:

30% of all JZ files save the data in JPG file format. JPEG is the standard image format for lossy and compressed image data. These files contain neither text nor words, but only data. The average file size is 240 KB with most files being between 170 KB and 2 MB in size. It is a modern file type. Certain words are almost always found in the files, such as OnePlus, JFIF, Exif, IN2020, !22222222222 and $.' ",#. Some examples of file names are IMG-20180601-WA0002133.jz or IMG-20180601-WA0004244.jz.
30% of all JZ files internally utilize the MP4 file format. MP4 is a multimedia container format used to store video and audio and allows streaming over the Internet. These files contain neither text nor words, but only data. The files are often between 1 MB and 15 MB in size. The following keywords are characteristic: \tkhd, lmvhd, trak, moov, ftypisom and isomiso2avc1mp41. A usual file name is YouCut_20180601_233554500.jz.

All other JZ files (40%) have no consistent format, frequently e.g. ZIP, zlib and GZIP. These files are often connected to city, audio or vivn. You can get all the details of your JZ file by dragging it onto this page or by clicking the button "Choose your .jz file to analyze" above.
