Abstract
A digital file may be stored on a storage device and deleted upon reading of the file. In one example, at least a portion of the stored file may be read, such as by a processor. In response to the reading of the stored file, at least part of the at least a portion of the stored file that has been read may be deleted. In further examples, the at least part of the at least a portion of the stored file may be deleted progressively while the stored file is being read, after a triggering event, or after a delay in time. According to another example, a user may provide an indication representative of the at least part of the at least a portion of the stored file that is to be deleted after the at least a portion of the stored file is read.
