About YZ1 files
A .yz1 file is a compressed archive, functioning like a digital suitcase to bundle and shrink multiple files. Historically associated with the Yazsoft Yz1 Archiver and the DeepFreezer utility (originally by Yamazaki Satoshi), this format offers high compression ratios but suffers from poor compatibility with modern operating systems. Users typically encounter friction because standard tools like Windows Explorer or macOS Finder treat these as unknown files, displaying a blank icon and refusing to open them. Unlike the universal ZIP format, a .yz1 file requires specific, often legacy, third-party software to unpack. To access the documents, images, or data inside, the most practical solution is converting the .yz1 container into a widely supported format like ZIP or 7Z, or using a specialized extraction tool.
Convert.Guru analyzes your YZ1 file, detects the exact format, and lets you read the text inside.
If you want to convert YZ1 file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use YouZip or similar software from the "Compressed Archive Storage" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to YZ1, try YouZip or another comparable tool in the "Compressed Archive Storage" category.
The YZ1 Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our YZ1 converter.
