Wharf's ingest and propagate files have overwhelmed my Macbook Pro.

From the link, it appears these files are related to a Cloud Based service

Is this computer using iCloud Drive, Google Drive, Drop Box or some other Cloud Based Service ?

Further, Backup to iCloud.

Perhaps one should read up on what iCloud is and Is Not

iCloud is only a conduit to have files on iCloud.

So other Devices you own & sing the Same Apple ID & using iCloud can access those files

It is not a Backup nor should it be consider a Backup

That is best left to Time Machine Backup  

Sign in to iCloud on all your devices

On another similar post, the person found all of the files seem to be referencing one specific file or folder. They moved that folder from the top level in documents to a sub folder and everything went back to normal.

I imagine it was the function of moving it not necessarily moving it down one level that had anything to do with the problem. I suspect it was somehow hung up on that file or folder in the move. Just broke it free.

I do have iCloud Drive. Is that what's causing problems? Can I use iCloud for backups and synchronizations without using iCloud Drive? In any case, what can I do about the large folders in Wharf. The link you cites seems not to address that question

The synchronization (Desktop, Documents) is done by FileProvider.

I have a wharf folder, but do not have any files inside of it. The parent folder is named with a unique ID and I cannot map that back to any of the iCloud FileProvider folders or the OneDrive FileProvider (I don't use OneDrive).

Much like my learned Colleague @Barney-15E

I too have as per below image including the " Purgatory " folder

Further, that folder in empty as per second image below

If I may go a little sideways User wrote " Can I use iCloud for backups and synchronizations without using iCloud Drive? "

Perhaps the reason the Purgatory files on your machine is so large is because you are syncing something like iPhone to the computer over a Direct Cabled Connection

I can not speak to that as I do not sync my iPhone to computer but to iCloud

I have the same issue. 350gb on my 120gb MacBook hard drive. With sub folders of 188gb in Propogate and 176gb in Ingest

only become an issue in past week.

I can’t run applications without Apple telling me I have no room
