There is a great write up and some easier solutions posted at http://ponderthebits.com/2017/01/mac-dumpster-diving-identifying-deleted-file-references-in-the-trash-ds_store-files-part-1/ 

Including this Terminal one-liner to convert a .DS_Store file to (mostly) text: 

xxd -p &lt;path/to/.DS_Store&gt; | sed 's/00//g' | tr -d '\n' | sed 's/\([0-9A-F]\{2\}\)/0x\1 /g' | xxd -r -p | strings | sed 's/ptb[LN]ustr//g'
