I have a series of photo attachments for a series of locations in the form of STX, GDBINDEX, GDBTABLE, FREELIST, HORIZON, and SPX files (54 total; screengrab below of most of them). However, I can't get ArcGIS to read the files, or even recognize them; the folder they're in keeps showing up as blank in the catalog pane, and when I try to drag them in it tells me it's an unsupported data type, without any further explanation. I'd appreciate any insight, thanks.
