Spacer

Spacer is a tag-based file explorer designed to provide an alternative to traditional folder-based file organization. It enables users to manage their files by assigning tags, creating spaces, setting priorities, and leaving memos, offering a customizable workflow that moves beyond hierarchical folder structures. The tool is aimed especially at designers and media-focused creators, but is positioned as useful for anyone seeking a more systematic approach to file management.

Core features of Spacer include the ability to tag files, group them into spaces based on projects or topics, and pin important files for quick access. Users can add memos to files for additional context and set priorities to highlight urgent items. The tool supports viewing all sub-files at once, regardless of folder depth, and provides a context pane for easily accessing file attributes. Flexible search capabilities allow users to find files quickly by searching across tags and memos. Spacer also supports rich metadata display, folder previews, document and code previews, and offers a dark mode for its interface.

Spacer operates entirely offline, with all data stored locally on the user's device. It does not collect any personal information or file-related data. An internet connection is only required for license activation and app updates. The application is available for both macOS and Windows platforms.

Spacer offers a demo mode that allows users to experience its core features with some restrictions, such as limits on the number of spaces and tags that can be created. The full version is available for a one-time purchase, providing unlimited access to all features without recurring subscription fees. Purchases are handled via Steam and are refundable within 14 days and less than two hours of use. This licensing model is designed to provide users with permanent access to the software after a single payment.
