 If an upload fails, the drive will show a dialog at the bottom of the screen. The error can also be seen in the Drive Uploader window or the logs (if they are enabled). The Uploader will make several attempts to upload a file if the error is recoverable (e.g. network failure or server retry error). You can retry or remove uploads through the Drive Uploader window.
+## Folder Upload
+Folders can be dropped into the drive through the Windows File Explorer or copied into the drive from local or network storage.  Note: The progress bar indicates the status of files being copied into the local drive cache. It does not indicate upload status.

+Use “Manage Uploads” to check when files are actually uploaded to the cloud.

+The Cloud Drive shows a circular loading button for files that are not yet uploaded. The icon changes to a green checkmark when the file is uploaded.
+If you are copying many large files, check you have enough space on your local machine to cache all these files. You can also tune the drive’s cache settings. For example, you could set the cached file to be removed after it has been uploaded.
+<WRAP center round tip 60%>
+For larger uploads use the File Fabric Cloud Explorer which uploads files straight to File Fabric (without using a local cache).

+## Copying Files & Folders
+Users can copy files and folders through the drive. As expected, if you copy files from a local drive or a network drive to the cloud drive, those files are uploaded to the File Fabric.
+However, if you copy a file or folder within the drive all he files are downloaded, copies, and then uploaded back through the File Fabric. This is an expensive operation for larger files and folders.
+Tip: To avoid using the desktop cache to transfer files use the File Fabric Cloud Explorer app or the web-based File Fabric Cloud File Manager to copy files. These apps ask the File Fabric to execute the copy, and it doesn’t need to use cache – it sends a “Copy Object” command directly to S3 storage.
+## Renaming Files & Folders
+Traditional file systems allow moving of files and folder hierarchies within the same drive. These are light operations where the file system is changing records in their directory catalog. File contents are not moved.
+Most object storage platforms however must physically copy a file’s contents when it is moved or renamed. The S3 API doesn’t even include a “rename” operation!
+Therefore, moving very large files and large folder hierarchies can take a long time and impact other users.  A rename or move of a large folder within the Windows File Manager will block applications from using the folder until the rename is complete (that folder may look like it’s frozen).
+When a file is moved within the drive, Windows tells the drive to rename the file. The Cloud Drive then sends a rename command to the File Fabric without transferring data. Since the S3 API doesn’t support rename, the S3 Drive sends a “Copy Object” followed by a “Delete". It also doesn’t need to transfer data.
+Users can also move folders within the drive too. The Cloud Drive sends one rename folder command to the File Fabric where the entire folder move is orchestrated.  The S3 Drive will send Copy/Delete commands to Amazon S3 for each file it finds.
+Tip: Move larger folders via the File Fabric Cloud File Manager. These operations run in the background. You can check their status under “Tasks”.
+WARNING: The File Fabric locks folder being moved, restricting subfolder and file changes. The subfolders can be still browsed and files downloaded however.
+The Cloud Drive will ask for confirmation before executing a folder rename or move.
