Problem with OneDrive

[MikeShawn]

Microsoft has been no help so maybe some one on here can help. I currently store a large number of files on my X: drive. To back them up to the cloud I use FFS to make a mirror copy into my OneDrive folder. That part works great, thank you FFS! After OneDrive syncs all of the new files with the cloud backup, I want to delete the files off my C: drive. I cannot use "Free Up Space" because that MS feature is grayed out. The problem, I believe, is that FFS is copying the files into my OneDrive folder as "Keep on this machine." That negates my ability to remove the new files unless I hunt them down one by one and change their status. MS offered one solution but that was to make all of the files available on my machine and then I can use the free up space function. So, they want me to download 50 GB of files just to be able to free up 50 MB. Is there a way for FFS to copy the file over and not set the status to "Keep on this machine?"

That won't be possible until OneDrive is natively supported.

This thread explains some people working with mapping their OneDrive as a drive letter, then you are syncing directly to the cloud instead of to a local folder and then uploading.

Thanks. That would be the ideal solution since i could then bypass the C: drive completely. Latest from MS is I have system corruption even though I told them I just did sfc repair followed by Dism to confirm. Actually, the guy admitted he didn't know what was wrong, that's a first.

sfc/dism is always what Microsoft will suggest, and they are very valuable tools, but only in the right situations. You don't have a problem to fix, so those won't be of any help.

Actually, MS did not recommend them. They just assumed I have system corruption and recommended I reinstall Windows and all of my programs and apps. I ran sfc, repaired Windows, and I still have the problem with OneDrive. For some reason FFS sets the file flag to "keep" when making the copy. If I can get it to stop everything should work fine. I also use Dropbox and their "free up space" works fine.

I've been able to dig up a little more info on my problem. Shown below are the file attributes used by OneDrive:
- online-only
FILE_ATTRIBUTE_PINNED : False
FILE_ATTRIBUTE_UNPINNED : True
FILE_ATTRIBUTE_RECALL_ON_DATA_ACCESS : True

- locally available
FILE_ATTRIBUTE_PINNED : False
FILE_ATTRIBUTE_UNPINNED : False
FILE_ATTRIBUTE_RECALL_ON_DATA_ACCESS : False

- always available
FILE_ATTRIBUTE_PINNED : True
FILE_ATTRIBUTE_UNPINNED : False
FILE_ATTRIBUTE_RECALL_ON_DATA_ACCESS : False

When FreeFileSync makes a mirror copy of a file into my OneDrive folder, the status is always available. This defeats the functionality of the Free Up Space command. I need FreeFileSync to stop setting FILE_ATTRIBUTE_PINNED = True and set it to False. Mirrored files will then show up as locally available and I can remove them using Free Up Space.
