Answer
You can use one of the following methods to quick access to the folder containing the currently opened PDF file.
Method 1: Right-Click on the Tab Bar
Right-click the document's tab bar and select "Open Containing Folder".
If the tab bar is not visible (e.g., when only one document is open), enable it via View > View Setting > Start Page.
Note: The "View>View Setting>Start Page" option is available in Version 2025.2, V14.0, and later versions.
Method 2: Use File Properties
Go to File > Properties > Description.
Click the file path in the Description section to open the containing folder, where the file will be highlighted.
Note: The second method is only available in Version 2025.2, V14.0, and later versions.
