That is correct. The HooToo's iPlugmate app:
- is keyed to the HooToo-specific USB DeviceID
- allows selecting any file on the external storage and emailing it.

Meanwhile, I'll use the TESTED, ACTUALLY WORKS HooToo.

See ya, Dave

Dave - I wasn't totally clear on the meaning of your post. Sorry if I'm being dense.

HooToo specifies the files that can be transferred and (not surprisingly) .IGC is not among them. I realize the .IGC files are basically text files that carry the .IGC extension - and HooToo does transfer .TXT files. The question is: Can you use HooToo to load a file from a logger with a USB port (that part seems obviously okay) and then plug HooToo into your iOS device, select that file as an iOS mail attachment (or maybe it's a HooToo iPlugmate mail app) - OR does iOS filter out files based on the extension without looking at the file content, which would make any .IGC files loaded onto the HooToo USB stick invisible to any app on the iPhone - even iPlugmate - because .IGC isn't listed a a supported file extension. If iOS looks at the file content .IGC might show up but if iOS looks only at the extension, it might not.

I could just buy a HooToo stick and find out I suppose. I just don't want to waste the time if it's fruitless.
