The "Online Storage" view is used display how much of your current online storage is in use. As such this view will not be applicable to free users.
There are two important things to note about the storage snapshot display and the reported file size. The reported file size is always the pre-compressed file size. The storage snapshot is always based on the compressed file size. Therefore the reported file size will never equal the snapshot file size. Your storage usage is based on the number shown in the snapshot which means that we charge you for compressed storage usage - saving you money.
Also note that the reported storage usage is not necessarily in sync with the file size shown in the folder list. This could be for two reasons. First, files may be in transit and therefore not represented in the stored snapshot. Second, there is a delay between the uploading a file in the file being reported to the user storage server.
The storage commands are used to work with your online storage account. There are four actions you can take with files on your storage account.
Delete - the delete command can be used to remove an attachment from the server and reclaim storage space. An attachment can only be deleted if it is no longer referenced by a current project or task. If the attachment is still referenced you will be prompted to first delete the reference before continuing to delete the file.
Open Folder - the open folder command can be used to open the local folder which contains the given attachment. This is useful if you wish to work with the given attachment.
Refresh - the refresh command is used to refresh the reported status of a given file or folder. Note that the refresh command does not call the storage server.
Activity - shows the activity for the selected attachment. For more information please see task details activity.
The folder list can be used to display all attachments which you own. Note that attachments which you do not own will not be displayed. Also note that only the root elements are attachments. In the example shown above the folder "PDF files" is not attachment - it is a subdirectory of attachment. If you wanted to delete the folder "PDF files" you need to delete the attachment "Project Files4".
The storage snapshot view shows you how much of your storage allocation is currently in use. Note the storage snapshot usage may be out of sync with the file size reported in the folder list due to the issues discussed above.
The credit history view shows you your storage credit history. Note that if you wish to increase the amount of storage available you can purchase additional credits (licenses).
