A solid offline-first setup does not require expensive software. Download Joplin for a free, open-source notebook that supports attachments and Markdown formatting. Keep sensitive credentials in KeePass rather than a browser password manager — the database file is portable and works without an internet connection. For editing configuration files or parsing server logs, download EmEditor — its large-file handling and regex search are hard to beat on Windows. Cloud file management rounds out the toolkit: S3 Browser for AWS-specific work, and Cyberduck's cross-protocol support for everything else.
