Im sure many folks working as a digi-tech do the same as me and keep a macOS File/Folder Info panel open for their Capture One session to know the total file size for the job. But I had the idea to improve this. Rather than rely on this native feature what if you just have the total size living on screen, updating in real-time?  


So I built [FolderMete](https://github.com/titleunknown/FolderMeter)r.

It lives in your menu bar and shows you the total size of your Capture One session folder at a glance. But once I had that, I thought it could do just a little bit more...  
Click the number and you get a breakdown of your Capture, Output, Trash, and Selects folders; including RAW file count, JPG count and subfolder count. It also includes a breakdown of much space each one is eating. It updates live as files arrive or move.

  
No setup beyond pointing it at your session folder.

What it does:

\- Shows total session size in the menu bar.  
\- Auto-detects Capture One session structure  
\- Tracks RAW and JPG counts separately  
\- Excludes CaptureOne cache folder(s) from file/folder counts  
\- Works on any folder if you're not shooting Capture One  
\- Lives in the menu bar only -- no dock icon, no clutter,  
 

How to get it:

The project is open source and free on [**GitHub**](https://github.com/titleunknown/FolderMeter). (There is an release available.)  
Its still an early build so you might run into some hiccups. I'll be updating as come across any myself. 

Since it's not distributed through the AppStore, when first launched: macOS will show a "downloaded from the internet" warning since it's not distributed through the App Store.  Right-click the app and choose Open the first time, or go to System Settings → Privacy & Security and click "Open Anyway"

  
Permissions: It will ask for: Files and Folders access. macOS will prompt the first time you pick a folder, asking if FolderMeter can access it. Just click Allow. 

Otherwise, you'll need Xcode to build it yourself for now. (Requires: macOS 14 or later, Xcode 15+)  
Building it takes about two minutes if you've never opened Xcode before. Clone the repo, open the project, hit run.  


I built this for myself first. If it helps other photographers and techs on set, great. If someone wants to contribute or fork it and make it better, even better.
