Thanks for the quick response. I saw the temp\imageranger_fs folder containing a lot of newly-generated *.fxz files, and that the contents of those files appear to refer to the indexed photo folders.
So you’re saying that those files are the ImageRanger index, and that it gets wiped and would need to be regenerated if you clear the Windows temp folder? Hmmm, I guess that’s ok as long as the user knows about it. It would help to update the documentation to make it clear that ImageRanger doesn’t store the index in the photo folders that it’s indexing.
Aside from that, the program does seem really useful, even if you already have other photo indexing programs, and it works fine for me.
