I think qrc__0.localstorage is the only interesting one. Attached you find a new zip file with the qrc__0.localstorage from my backup. I'am not 100% sure, that the first zip file is the right one. I hope it helps.
Sorry to dredge up an old thread but this just happened to me and I fixed it by deleting everything in C:\Users\mpflaging\AppData\Local\Sencha\Sencha Architect 3.1
But I did back it up. See attached. I had to take out the file "xds-3.1.0.001851.ion" (57Mb) and the subdirs (23Mb) because your site does not allow files above 488.3 KB (and also fails silently if this is exceeded).
