Abstract: A computer-implemented method according to one embodiment includes performing a query for finding files that meet at least one predefined criterion. The at least one predefined criterion includes a file size that is less than a predefined fraction of a predetermined threshold file size. Performing the query includes sequentially performing additional querying in response to finding a first file that meets the at least one predefined criterion. As files are found in the additional querying, for each sequence of additional querying, the method includes determining whether a total storage size of files found during performance of the query exceeds the predetermined threshold file size. In response to a determination that the total storage size of the files found during performance of the query exceeds the predetermined threshold file size, the files are consolidated into a consolidation file. The method further includes writing the consolidation file to a magnetic recording tape.
