Abstract: A computer-implemented process for replacing old files having old names on a permanent storage medium with new files in volatile memory. Some of these files may be opaque files, which are old files that have become new files without undergoing any changes, other than possibly name changes. The primary steps of this replacement can comprise first saving the non-opaque new files onto the permanent storage medium and assigning them temporary filenames. An opaque recovery file listing the old name and a temporary name for each opaque file is created. A primary recovery file listing the temporary name and a final name for each new file is created. After the names of the opaque files are changed to their temporary names, the names of the non-opaque old files are changed from their old names to backup names. Then, the names of the new files are changed from their temporary names to their final names. The recovery files and the old files can be deleted.

Abstract: An indexable glass shipping apparatus that can be used in conjunction with reusable steel racks or other glass shipment racks. The apparatus includes a catalog made up of a plurality of sheets of shock absorbent material, spaced from each other to accommodate glass panes between. The sheets are fastened together by a series of fasteners located along a lower edge of the catalog. In one embodiment, the lower edge is journaled to conform to the shape of a steel rack, to minimize any risk of longitudinal movement of the catalog on the rack. The sheets of the catalog may be indexed to facilitate selection of glass panes. In addition, an outer protective cover is provided, that is secured to the outside of the catalog after it is mounted on the glass shipment rack.
