file/ directory duplicates recording folders

BenF8

Hello OpenBCI, my name is Ben, I just joined. This is my first post so if I'm posting in the wrong section of the forum please let me know!

I just installed the OpenBCI GUI v5.1.0 for Mac from the Downloads page, on macOS Ventura 13.3

In the 'Ganglion Getting Started Guide' on the website there is an Info box that says:

By default, the GUI stores all user data and raw EEG recordings in [USER]/Documents/OpenBCI_GUI and names each session with an autogenerated timestamp by default.

While my recordings are correctly stored under that path (e.g.[User]/Documents/OpenBCI_GUI/Recordings/OpenBCISession_Ganglion-Tutorial) and each recording folder has a .w, .csv, or a .txt file, I also have a random file/ folder in my home directory that seems to duplicate my recordings, except it doesn't include actual data files.

Is this a bug? Can this folder be safely deleted? Is there some option in settings I need to adjust in order for this not to happen?

Thank you,

Ben

These appear to be temporary folders used to write BrainFlow CSV at runtime. Upon closing the file, it is then moved to the specified location, which by default is next to OpenBCI CSV files in User/Documents/OpenBCI_GUI/Recordings/SessionName.

@retiutut I actually think the BrainFlow data is being written to the "final" destination in User/Documents/OpenBCI_GUI/Recordings/SessionName. In the image attached you can see that when I'm streaming it's creating & writing to the .w files (which is why iCloud is not uploading them). Once I stop recording, the files stop being written to and they're backed up properly. So nothing get's written to the duplicate User/Documents/file/User/Documents/OpenBCI_GUI/Recordings/SessionName. Setting a Custom location also doesn't fix the problem. Only setting location to None avoids the creation of the duplicate folders, but then you don't get a .w or .csv file.
