1. A non-transitory memory device storing operational instructions that, when executed by a processing module, causes the processing module to: interpret a file command, wherein the file command includes a file name for a data object; determine that the data object is stored in stored in a distributed storage network (DSN) memory, wherein the data object is encoded using a dispersed storage error encoding function to produce a set of encoded data segments and interleaving an encoded data segment of the set of encoded data segments into a number X of a plurality of encoded data slices wherein the number X of the plurality of encoded data slices is stored in the DSN memory and wherein the data object is encoded using the error encoding dispersal storage function by: arranging data blocks of the data object into a data matrix; generating an encoded data matrix based on the data matrix and an encoding matrix; and arranging data blocks of the encoded data matrix into the set of encoded data segments; retrieve from the DSN memory at least a number T of the plurality of encoded data slices, wherein the number T of the plurality of encoded data slices is needed to reconstruct the data object based on the error encoding dispersal storage function and wherein the number T equals less than the number X; and reconstruct the data object from at least the number T of the plurality of encoded data slices to produce a reconstructed data object
