If you run out of storage space, manage it to prevent it from happening again.

Help with storage space shortage tasks according to the goals and materials below. [input] Goals and usage situations: I want to clear the blockage from lack of storage space and decide my next course of action. Resources to review: Storage space analysis screen Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Check the purpose and cleanup impact of large items and avoid guessing deleting system files. [Results to be created this time] Change only the parts where the cause has been identified into preventive rules. Present items to be checked regularly and abnormal signals/check cycles according to the usage environment. Please do not recommend installing general optimization programs or disabling unnecessary security features. [Working Principle] After checking the operating system and version, provide guidance on the relevant environment. Before changing files, accounts, or settings, explain the implications and recovery methods, and don't tell anyone you've actually deleted a deletion candidate. Do not arbitrarily disable business management policies or security protections. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Ensure that causes and preventative actions are linked and maintenance burdens are realistic. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
