What is a UZED file?
A UZED file is a Zip-compressed archive that contains a .GEDCOM genealogy file and .XML metadata file. It is used by MyHeritage Family Tree Builder, which is a free genealogy application, to store genealogy information, such as a family tree and characteristics about individuals within the family tree.
UZED files are primarily used by version 7 of MyHeritage Family Tree Builder. They replaced .ZED files, which are used by versions 1 - 6 of the software.
UZED files are similar to ZED files but instead of storing only a Zip-compressed GEDCOM file, it also includes a metadata.xml file that stores metadata about the family tree. Also, the GEDCOM file compressed in the UZED archive stores Unicode UTF-8-encoded text instead of ANSI-encoded text, which the GEDCOM file in the ZED archive utilizes.
ZED and UZED files are often referred to as being saved in the ZEDCOM (Zipped-GEDCOM) format. The files were replaced by .FTB SQLite database files with the release of version 8 of MyHeritage Family Tree Builder.
How to open a UZED file
While UZED files have been replaced by FTB files, you can still open them with MyHeritage Family Tree Builder. To open a ZED file with Family Tree Builder, select File → Open Project....
Since UZED files are compressed with Zip compression, you can also rename the .uzed file extension to .zip, decompress the archive with a Zip utility, such as Microsoft File Explorer (Windows), Corel WinZip (Windows), or Apple Archive Utility, then open the GEDCOM file with a genealogy program and XML file with a text editor.
