At the same time, you must back up the EFS certificate and private key to prevent data loss. EFS relies on user account security and only supports NTFS. It is suitable for stand-alone privacy protection, but is not suitable for multi-user sharing or high-security threat environments. Compared with traditional password encryption, EFS is integrated with system login, without repeated input of passwords, but the account password is securely bound. For higher security requirements, you can choose third-party tools such as BitLocker full disk encryption or VeraCrypt. When backing up the key, you should export the PFX format certificate and set a strong password to store it in a secure location.

The most direct way is to recall the storage location, usually in folders such as desktop, documents, downloads, etc.; if it cannot be found, you can use the system search function. File "missing" is mostly due to problems such as unattention of the saving path, name memory deviation, file hiding or cloud synchronization. Efficient management suggestions: Classify by project, time, and type, make good use of quick access, clean and archive regularly, and standardize naming. Windows search and search through File Explorer and taskbar, while macOS relies on finder and Spotlight, which is smarter and more efficient. Mastering tools and developing good habits is the key.
