You can manually upload data via the SkyDrive website. SD will consider the "Orginal" location of those files to be in the cloud, thus preserving them from deletion.
However, you will also need to go into the SkyDrive plugin on your computer and disable syncing back down again. If you do not do this, SkyDrive will re-download all the files into your Skydrive folder once they are uploaded.
to do this:
- Right click on the SkyDrive app in the taskbar.
- Click settings
- Click the "Choose Folders" tab.
- Click "Choose Folders"
- Click "Choose folders to Sync"
- Uncheck any folders on your Skydrive you do not want to be automatically downloaded.
once this is done, you will have a set of data on the Skydrive that will ONLY be there, not locally, and not set to re download automatically.
Use the answer to this question to mount your skydrive as a network drive, then simply copy/paste. You will still need to disable the sync of these folders if you do not want them to automatically re-download.
