Extract text from Split ZIP archives (Z1)
To convert Z1 Archives to another format, you need WinZip or other Compressed software.
To convert other file formats to the "Split Archive File" file type, you need software like WinZip or a similar tool.
The .Z1 file extension is primarily used for Split ZIP Archives created by file compression software like WinZip. When a standard archive is too large for an email attachment limit or a specific storage medium, the archiver splits the data into multiple sequential parts. The main file is usually named ZIP, and the fragmented parts are given extensions like Z01, Z02, or in some workflows, .Z1.
Less commonly, the .Z1 extension represents a 3D design model file generated by i3DOne, an educational 3D modeling software, or a legacy Z-machine Z-code File used for classic interactive fiction games developed by Infocom.
Handling .Z1 files is notoriously frustrating for everyday users. For split archives, a single .Z1 file is completely useless on its own. You must possess every single part of the split archive in the same folder to successfully extract the underlying data. Furthermore, many default operating system extraction tools (like Windows Explorer) lack native support for reassembling split archives, forcing users to download specialized third-party tools. If your .Z1 file is an i3DOne project, you face a different problem: it is a highly proprietary CAD format that cannot be directly opened by standard 3D viewers or web browsers.
To resolve these compatibility issues, it is best to combine split archives into a single, unified ZIP or 7Z file for easy sharing. For 3D files, exporting to a universal format like STL or OBJ is strongly recommended to ensure compatibility with 3D printers and modern CAD environments.
Converting or extracting a .Z1 file is difficult because standard online converters fail to process incomplete archive parts or proprietary 3D data. Often, only the original software can properly read or export the data. However, convert.guru provides a pragmatic solution: just drag and drop your file to see what it is, inspect the internal content, and convert it if the underlying format is supported.
Convert.Guru analyzes your Z1 file, detects the exact format, and lets you read the text inside.
Users also converted Z01, PNG, ZPX, ZND and ZNC files.
If you want to convert Z1 file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use WinZip or similar software from the "Split Archive Storage" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to Z1, try WinZip or another comparable tool in the "Split Archive Storage" category.
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 Z1 converter.
