Directory Opus is a Windows file manager for browsing folders, transferring files and organizing large collections. Its windows combine folder displays with tools for renaming, comparing, searching and inspecting files. You can use it alongside File Explorer or enable Explorer Replacement mode so that ordinary folder-opening actions launch an Opus window.
Browsing folders in a Lister
A Directory Opus window is called a Lister. It can show one folder or two, with folder trees for navigation and tabs for keeping additional locations open.
In a dual display, one location acts as the source and the other as the destination. Selecting files on the source side and invoking a copy or move sends them to the destination without routing the operation through the clipboard. The same arrangement works between separate Lister windows.
Folder formats control which columns appear and how entries are sorted or grouped. You can save these settings for a particular folder, its descendants or folders matching a rule. A picture collection can therefore retain different display settings from a directory of documents.
Expandable folders reveal nested contents inside the current file display. Flat View goes further by presenting files from child folders together, either as a flat list or grouped by their original locations. These views change how the directory tree is presented; the files remain in their existing folders.
File transfers
Copying and moving also work through drag-and-drop, toolbar commands and the usual cut, copy and paste operations. Directory Opus can queue multiple copy jobs so that transfers wait their turn rather than all competing for the same disk or connection. Filters limit which files inside a folder are copied, while filename collisions open a dialog for choosing how to handle the existing and incoming files.
Archives participate in this folder-based workflow. You can create a ZIP archive and add files by dragging them in, pasting them or copying from the opposite display. ZIP support is built in, while plugins provide access to additional archive formats.
The built-in FTP client brings remote server directories into the file displays. Connections can be entered in the location field, made through a connection dialog or saved in an address book. Remote files can then be copied, renamed or deleted through the same interface used for local folders.
Batch renaming
Directory Opus handles a single filename through inline editing, but its Advanced Rename tool applies rules across a selection. Wildcard expressions retain chosen parts of existing names, numbering adds sequences, and metadata can supply information for the new names.
Rename macros provide another approach: keyboard editing actions can be recorded and applied across the selected names. Scripts handle more involved transformations.
Folder synchronization
Synchronization begins with a comparison between two locations. A one-way job can decide what to replace using names, sizes, modification times or a byte-by-byte comparison. A two-way job copies in both directions and uses modification dates to choose the newer file when matching files exist on both sides. Targets can include local folders, network shares, archives and FTP locations.
The comparison marks proposed copy and deletion actions in the file displays before the transfer runs. You can inspect those marks and change individual actions, then start synchronization. Filters and excluded folders narrow the job. In one-way mode, an optional setting also removes destination files absent from the source.
Finding files and duplicates
The filter bar narrows the current display with a typed pattern. Searching instead looks for files beyond the open folder, using names, attributes and metadata. Directory Opus includes its own search tools and can work with indexed search services such as Windows Search and Everything. Search presets preserve settings for recurring queries.
The duplicate finder searches selected folders or drives for repeated files, or for copies of particular files you specify. Its comparison modes range from matching names or sizes to calculating MD5 checksums. Results appear in a collection grouped by duplicate set. Selection controls help choose which copies to retain or remove; deletion remains a separate file operation after the search.
Working with media files
A viewer pane displays supported files beside the folder list, while a separate viewer can show images and run slideshows. Movie and document viewing depend on the available format support and plugins. The metadata pane follows the current selection and exposes properties appropriate to those file types, such as picture information, music tags or document details.
Shared properties can be edited across several selected files. Comments, ratings and tags are stored inside formats that support them; for other files, the fallback uses NTFS alternate data streams. That fallback does not provide the same metadata storage on other file systems.
The image converter processes selected pictures individually or as a batch. It can write BMP, GIF, PNG and JPEG files, resize by dimensions or percentage, preserve proportions and rotate pictures, including rotation based on EXIF orientation. Converted images can go to the destination folder, and filename suffixes distinguish outputs from their sources.
Directory Opus customization and licensing
Toolbars, menus and keyboard shortcuts can be edited around the operations you use. Buttons and hotkeys can invoke Opus commands or external programs, while custom floating toolbars can serve as program launchers. The scripting interface extends this further with additional commands and dialogs.
Directory Opus is paid software with a time-limited evaluation. A standard license permits continued use indefinitely and includes an initial period of updates; renewing update access is separate from continuing to use the licensed program.
