Files guide
A file shelf for Mac: keep files ready to drag
Momo’s file shelf gives you a temporary place to keep files handy between apps. Drop a file on Momo, then drag it out when you are ready. The shelf keeps a reference to the original, rather than moving it into a new folder.
Stage and preview the files for your next task
- Drop local files on Momo, or open Files and choose Add files….
- Use the thumbnails to find the file you need. Select it and press Space, double-click it, or choose Quick Look for a preview.
- Command-click to select several files, or Shift-click for a range. Drag the selection into an app that accepts those files.
- Choose Remove from shelf when you are finished with the selected references.
For example, gather a PDF and screenshots before composing an email, then drag the selection into the attachment area. The receiving app decides how to handle the drop. A preview does not move the original or add it to a cloud service.
References are convenient, but are not backups
Your original files stay where they are. Removing an item from the shelf removes its reference and does not delete the original file. The shelf stores its list locally and holds up to 50 references.
A reference is not a second copy of the file. If the original cannot be found or its drive is disconnected, the shelf can show Missing and you cannot drag that unavailable file out. Restore access to the original or add the correct file again. Keep important files in your normal storage and backup workflow.
Export a different image format when you need one
Select one available image in Files, then choose Convert image…. Export JPEG, PNG or HEIC as a separate copy. Maximum-edge options include original resolution, 1024, 2048 and 4096 pixels; JPEG and HEIC also offer a quality control.
The export keeps the source unchanged, applies orientation and removes metadata. It exports the first frame, so it is not a way to preserve an animation. JPEG does not retain transparency; choose an appropriate format for the image you are sending.
Keep the shelf small and purposeful
Treat the shelf as a staging area for a handoff: assets for a message, screenshots for a bug report or documents for a review. Clear out references after the task to make the next batch easier to find.
For copied text, use Clipboard instead. For a thought you want to edit, use Notes. The shelf is for local file references, not cloud storage or a replacement for Finder.
Common questions
Does removing a shelf item delete my file?
No. Removing a shelf item removes its reference; the original stays in its existing location.
How many files can I keep on the shelf?
The shelf holds up to 50 references. Remove references you no longer need before adding more.
Does image conversion overwrite the source?
No. Momo exports a copy and asks you to choose a different filename if you select the source path.
Can I preview and drag several files?
Yes. Use Space or double-click for Quick Look. Command/Shift selection lets you select several items, then drag their original file references into an app that accepts them.
