.UVZ file extension
To open .UVZ files on Windows, try opening the .uvz file with an archive utility (open it the way you would open a .zip) to inspect/extract the contents.
To open a .uvz file, treat it as an UltraViolet (DECE) media package stored in a ZIP container. You can usually inspect it with a ZIP tool, but actually using the packaged content depends on software/services that understand the UltraViolet/DECE package structure.

How to open .UVZ files
Use these platform-specific instructions to open .UVZ files safely.
Windows
- Try opening the .uvz file with an archive utility (open it the way you would open a .zip) to inspect/extract the contents.
- If you need to use it as an UltraViolet/DECE media package (not just extract files), look for software/workflows that explicitly support DECE/UltraViolet “media packages” and the media type application/vnd.dece.zip.
Mac
- Try opening the .uvz file with an archive utility (or rename a copy to .zip and open that copy) to inspect/extract the contents.
- For full UltraViolet/DECE package handling, use tools/workflows that explicitly support DECE packaging (application/vnd.dece.zip).
Linux
- Open the .uvz file with a ZIP-capable archive tool to inspect/extract contents (it is a ZIP-based container).
- If your desktop environment does not recognize .uvz, add a MIME association via the shared MIME-info mechanism (map *.uvz to application/vnd.dece.zip) so file managers handle it consistently.
iOS
- iOS may not recognize .uvz as a supported package type; if you can’t open it in Files, transfer it to a desktop system and inspect it with a ZIP tool.
Android
- Try a ZIP-capable file manager/archive app to view or extract the contents; if the app refuses due to the extension, rename a copy to .zip and try again.
- If you need DECE/UltraViolet-specific processing, move the file to a desktop environment with appropriate DECE-aware tooling/workflows.
Security notes
- .uvz is a ZIP-based container; like other archive formats, it can contain many files and nested data, so be cautious with unexpected .uvz files (they can hide content you did not intend to open).
- If you rename a .uvz to .zip to open it, treat the extracted contents as untrusted until you understand what was inside; inspect before opening extracted executables or scripts.
- Because .uvz may not be widely supported, some third-party tools may have less-tested parsers for DECE-specific structures; prefer well-maintained archive utilities for basic extraction and use the DECE specification when validating package expectations.
Can't open this file?
These are the most common causes and fixes when .UVZ files fail to open.
Common reasons
- The file won’t open because the app doesn’t recognize .uvz
- It extracts like a ZIP, but the result doesn’t ‘play’ or isn’t usable
- MIME type is misdetected (treated as generic ZIP or unknown)
Fix steps
- Make a copy of the file and rename the copy from .uvz to .zip, then open the copy with a ZIP-capable tool.
- If you are on Linux, ensure *.uvz is associated with application/vnd.dece.zip via the shared MIME-info database so your file manager can pick an archive handler.
OS-specific troubleshooting
What is a .UVZ file?
.uvz is the file extension used by the UltraViolet File Format (DECE) for its media package, and it is a ZIP-compressed container. The DECE specification associates it with the IANA-registered media type application/vnd.dece.zip. In practice it behaves like a .zip at the container level, while the internal layout is defined by the DECE Media Package specification.
Background
The .uvz extension is used for UltraViolet/DECE packaging: a standardized way to bundle media and related package data in a single ZIP-based file. The DECE “Media Package” specification defines how the package is structured and explicitly ties the format to both the .uvz extension and the vendor media type application/vnd.dece.zip.
On many systems, .uvz will not have a dedicated default application because it is a niche, domain-specific package format. However, because it is ZIP-based, common archive utilities can often open it for inspection and extraction, which is useful for troubleshooting or verifying contents.
On Linux desktops, file type recognition commonly relies on the freedesktop.org shared MIME-info database concept (filename globs like *.uvz mapped to a MIME type). Technical MIME mapping references commonly associate .uvz with application/vnd.dece.zip.
Common MIME types: application/vnd.dece.zip

Common .UVZ issues
The file won’t open because the app doesn’t recognize .uvz
Many tools key off the filename extension; .uvz is uncommon even though it is ZIP-based, so some archive apps won’t offer to open it directly.
- Make a copy of the file and rename the copy from .uvz to .zip, then open the copy with a ZIP-capable tool.
- If you are on Linux, ensure *.uvz is associated with application/vnd.dece.zip via the shared MIME-info database so your file manager can pick an archive handler.
It extracts like a ZIP, but the result doesn’t ‘play’ or isn’t usable
A .uvz is not just arbitrary ZIP data; it is a DECE Media Package with a specific internal structure. Extracting may produce files that still require DECE/UltraViolet-aware software/workflows to interpret correctly.
- Verify that your goal is inspection/extraction vs. proper DECE package ingestion; for the latter you need tools/workflows that explicitly support the DECE Media Package specification.
- Use the DECE Media Package specification to understand the expected internal layout and metadata for troubleshooting.
MIME type is misdetected (treated as generic ZIP or unknown)
Some systems or applications may not include an up-to-date mapping for .uvz, so they may label it as a generic ZIP or as an unknown type, affecting how it opens or is shared.
- When configuring servers, email gateways, or file type rules, use application/vnd.dece.zip for .uvz when you need the specific vendor type.
- On Linux desktops, add/adjust a shared MIME-info rule so *.uvz maps to application/vnd.dece.zip.
FAQ
Is a .uvz file just a .zip?
At the container level it is ZIP-based, but the .uvz extension identifies it as an UltraViolet/DECE media package with a structure defined by the DECE Media Package specification.
What MIME type should be used for .uvz?
The DECE/UltraViolet packaging is associated with the vendor media type application/vnd.dece.zip (registered with IANA).
Why does my computer label it as an unknown file?
.uvz is relatively uncommon, so your system may not have a built-in extension-to-MIME association. On Linux, the shared MIME-info database mechanism can be used to map *.uvz to application/vnd.dece.zip.
Can I safely rename .uvz to .zip?
Renaming a copy to .zip is a common workaround for opening it with ZIP tools because it is ZIP-based. Do this only to a copy so you don’t lose the original extension used to indicate DECE/UltraViolet packaging.
