If the file is moved or renamed, the hyperlink may no longer work.

Example:
C:\Users\ADMIN\Downloads\try.ods

Relative Hyperlink:

It stores the location of a file in relation to the current location.
It depends on the location of the current spreadsheet.
It can continue to work when the related files are moved together while maintaining their relative locations.

Example:
Admin\Downloads\try.ods

It makes data entry faster.
It allows multiple users to work together.
It improves collaboration.
It makes sharing and updating information easier.
It helps users work on the same spreadsheet more efficiently.
