Abstract
In accordance with one or more aspects, one or more portions of each of multiple files that have been freed are determined. One or more delete notifications are generated identifying the one or more portions of the multiple files. Each portion is identified as a range of data on a storage device, and each delete notification includes one or more ranges of data on the storage device. These generated delete notifications are then sent to a storage stack. Additionally, an application can determine that one or more ranges of data of a storage device are to be freed and send a delete notification, in the absence of a file system on the device, to the storage stack identifying the one or more ranges of data of the storage device that are to be freed.
