Abstract
A data storage system having data locking and unlocking functions and a method therefor are provided. The data locking and unlocking method includes: when a used capacity of a storage device is equal to or greater than a first threshold, locking a plurality of folders of the foregoing storage device; preventing the folders from being unlocked when the used capacity is greater than or equal to a second threshold; unlocking the locked folders according to a first unlock signal when the used capacity is less than the first threshold; and unlocking the locked folders according to a second unlock signal when the used capacity is between the first threshold and the second threshold. The foregoing second threshold is greater than the first threshold.
