The original physical report contained a CD in the back with files on it for Appendices B-F, as well as a set of Figures and a set of Plates. The report describes the content of these files in more detail. Each set of files (individual Appendices, Figures, and Plates) has been zipped and uploaded as a separate folder attached to this record. This is an account of the number and types of files uploaded, as well as any file format conversions that took place. Appendix B contains 2 .xls (Microsoft Excel 97-2003) files; these were converted to .csv (Comma-Separated Values) to improve accessibility and .xlsx (Microsoft Excel 2016) to retain formulas that were lost in the .csv files. All 3 versions (6 files total) were uploaded. Appendix C contains 26 .jpg (JPEG) files, which were uploaded as is. Appendix D contains 6 .pdf (Portable Document Format) files, which had OCR (Optical Character Recognition) applied and were converted to the archival form of PDF files, PDF/A, before being uploaded. Appendix E contains 1 .xls file; this was converted to .xlsx, and each individual sheet was also converted to a separate .csv file. All 3 versions (7 files total) were uploaded. Appendix F contains 2 .doc (Microsoft Word 97-2003) files and 5 subfolders. The .doc files were converted to PDF/A files and both versions were uploaded. The subfolders contain a total of 6 sub-subfolders; all of these together originally contained a total of 504 files (.bak, .jpg, .hpf, .rtf, and .xrdml). The .bak, .jpg, .hpf, and .xrdml files were uploaded as is, because the file format is supported (.jpg), acceptably open (.xrdml), or too specific to have a better option to convert to (.bak and .hpf). The .rtf (Rich Text Format) files were converted to PDF/A files and both versions were uploaded. A total of 590 files were uploaded in Appendix F. Figures originally contained 73 files, 46 .jpg and 27 .rtf. The .jpg files were uploaded as is; the .rtf files were converted to PDF/A files and both versions were uploaded. A total of 100 files were uploaded in Figures. Plates contains 37 .pdf files, which were converted to PDF/A files before being uploaded.
