Thanks for reaching out about this.
odrive has several safeguards in place, which makes it very difficult to have files that are truly lost. I’ll see if we can get things sorted out here.
The most important thing to note is that your files and folders should all still be in Google Drive. When you unlink storage from odrive, it can no longer access that storage. The storage stays where it is (Google Drive, in this case), however. This means all of your files are still available in Google Drive. odrive just can’t see/access them because you’ve removed odrive’s access to the storage.
Can you send a diagnostic from the odrive tray menu? (See How do I send a diagnostic? for how to do that). This will provide me with information about your environment and configuration.
.cloud file is a representation of a file that exists in your cloud storage.
It sounds like you unlinked your Google Drive from odrive. When you do this, odrive will see that you have removed (deleted) the Google Drive link and will move the corresponding local folder to your OS Recycle Bin (in Windows) or Trash (Mac). It does this because odrive no longer has any access to that Google Drive account, so when odrive tries to list your linked storage, that account is not returned in the listing anymore (you have deleted it from your odrive account)
When unlinking your storage from odrive, the storage is unaffected. This means your Google Drive files and folders all remain as they are in the cloud. odrive just doesn’t have access to them anymore.
If you re-link your Google Drive storage, odrive will see the storage listed and it will show up on your local system again. At that point you can browse and sync it, once more.
I would need to take a look at where these are located. In general, you will see this message if you try to sync a placeholder file that corresponds to storage that odrive no longer has access to.
I will need to take a look at your diagnostic to see how things are configured, but you would need to have your Google Drive re-linked to be able to access any data that is stored in your Google Drive.
