Sync from laptop to ios

I would be grateful for any advice anyone could give on this problem. I have a file on my laptop which I would like to sync with my iOS devices., These already contain files and I tried synching this one with the same external Dropbox folder (apps/Scrivener). The file did not show up on my iOS devices but in another place on my laptop. I think I followed the same steps the last time I synex additional files. I lke keeping things simple and tidy, and would like to sync everything with apps/Scrivener, but something’s not right.

Thanks in advance.

Are hou talking about a file in general or a Scrivener project?
If you save your Scriv project in the folder where your iDevices are looking for Scriv projects, iyour iDevice will see it.

Thanks, that did it.
