ux0home

ux0home is an informal term used in PlayStation Vita homebrew communities to describe a directory on the ux0: storage partition that is intended to hold user-specific data for applications and games. It is not an official Sony designation and does not appear in official documentation.

In PS Vita architecture, the system uses multiple storage partitions. ux0: is typically the primary internal storage where applications and user data reside, while uma0: represents the memory card storage. Some homebrew projects reference a ux0:/home directory to separate user data, such as settings or saves, from the main application files. Because ux0home is not standardized, its exact location and contents can vary between software and firmware versions.

Usage of ux0home in practice varies by project. Certain homebrew tools or scripts may read from or write to ux0:/home to persist configuration or save data across launches, while others may use different paths. Documentation and guides from the community may mention ux0:/home or related paths, but such references are informal and depend on the specific toolset being used.

Limitations and cautions are important. Since ux0home is not an official feature, not all devices or firmware revisions guarantee its existence or structure. Modifying files in ux0 or any user data area can affect application behavior or stability. Users should back up data before making changes and rely on trusted tools and guides when interacting with such directories.
