GPO IUCFL Collection Explorer

A tool to help look for file formats and patterns in the Indiana University CD-ROM & Floppy Library

This tool was developed as part of this piece of work with the U.S. Government Publishing Office. The work was funded by the Digital Preservation Coalition Member Support programme. If you have any questions, please do get in touch.

Purpose

The purpose of this tool is to help find formats and patterns of file extensions in the copy of the Indiana University CD-ROM & Floppy Library held by the U.S. Government Publishing Office.

The full list of file extensions has been included in the collection profiles part of the workbench, so you can get an overview all the extensions there. You can then use this page to look at individual extensions in more detail.

See the full report for more information about this project.

This system depends on a database file containing information on over six million files. It might take a while (minutes) to start up and respond, depending on your device, download speed and the host server status.

Query by File Extension

First, enter an extension of interest, e.g. dbf/pdf/bat/shp.

Found items with extensions matching '.'. The following table shoes a list of all items that match:

If you select an item in the list (using the small circle in the left-hand column), more details about the item will be shown below (although it might take a moment to update).

All file extensions in this item

This table shows all of the file extensions in the selected item, and counts up how many files have that extension, and now many bytes these files take up in total. This can be useful for spotting items with similar patterns of files extensions and file extensions that commonly appear together.

Files with extension '' in the selected item

This lists files in the item that have the extension '' (up to 1,000 files). Can be slow to load/refresh.

Focus on Floppy Disks

This part uses a query that focusses on floppy disks only, to make it easier to find example files from floppy media. It limits the number of matches it returns, to avoid overloading the results table.

Found items with paths matching ''. The following table shoes a list of all items that match:
