Directory Opus Manual

The Undo command can (usually) be used to undo the most recent action. Most actions can be undone - for example, if you rename a group of files incorrectly with a wildcard, you can undo the rename fairly easily. File deletes, however, can not be undone unless the delete was done to the recycle bin. You can find the Undo command in the Edit menu in a Lister (or press Ctrl+Z).

Opus maintains a history of undoable functions. From the Undo List sub-menu, you can see the ten most recent actions, and undo any of them by selecting it from the list. Selecting the More… command from that sub-menu displays the Utility Panel, showing the Undo Log page. This page displays a full list of undoable actions, and you can undo one, many or all actions from this page at the click of a button.

What happens when you undo an action can work in two ways, controlled by the Sequential undo option in Preferences.

• When Sequential undo is turned off, a new undo entry is created at the top of the undo list to undo the undo. For example, if you rename a file, pressing Ctrl+Z would undo the rename. Pressing Ctrl+Z again would redo the rename.
• When Sequential undo is turned on, undoing an operation no longer adds the undone action at the top of the undo list. Instead, it adds it to a separate "redo" list. This lets you undo multiple actions in sequence, and optionally redo them in reverse order if needed, using the Undo REDO command.

While the undo log only shows the most recent undoable actions in the current session, the file log maintains a persistent log of all file operations (undoable or not). You can access the File Log from the Utility Panel, or select the command directly from the Help menu.

By default the file log records the last 1000 file operations. You can see what sort of action occurred, the file involved, when it happened, and in the case of a copy or move, the destination folder.

The file log can be extremely useful at times - if you've ever found that a file you knew was there has mysteriously disappeared, you can often find out what happened to it through the log. You can use the filter field to search for a file by name or path.

The Save button at the top of the log lets you export the log as a text file - useful if it's quite large and you want to search it in a text editor. You can configure the maximum size of the log, and control which operations are recorded, from the File Operations / Logging page in Preferences.
