Where should most customized files be stored to avoid being overwritten during updates?

Storing most customized files in the home folder is the best practice because this location is specific to each user and is less likely to be affected by system updates. System updates typically target shared system directories where default files reside, which could lead to customized content being overwritten or lost if these files are not properly safeguarded.

The home folder is designed for personal use, providing a dedicated space for users to manage their files and configurations without interference from system-wide changes. This makes it an ideal location for customized files, as updates are less likely to inadvertently alter user-specific data.

In contrast, other locations such as the temp folder are meant for temporary data storage and can be cleared regularly by the system, leading to potential loss of customized files. The system folder is critical for the operating system's functionality, and any modifications in this area can easily be impacted by updates. Meanwhile, a shared folder typically allows multiple users access to certain files, increasing the risk of accidental overwrites while also exposing customized documents to alterations by others. Hence, the home folder is the safest and most reliable choice for storing customized files.
