Hi Tim,
we've talked on the AERO about an automatic sync between all devices already and I understand that this is not possible for certain reasons. However, right now the handling of SD data is not very comfortable.

In my case, I plan everything on my PC, upload it, and just open it on my iPad. I do not do any planning on the tablet. So all data flows from my PC to my tablet, with the only exception of the flight logs.

It would be very helpful to have a "Upload everything" button, which pushes all planned routes, aircraft, settings, hidden NOTAMs and so on to the cloud at once. On to tablet, a "download everything" would be very helpful.

Regards,
Johnny

Hi Tim,
I kinda lost track on this thread. Combining several legs to one file helps to decrease the number of files drastiacally. However, it would be great to have a "Upload all aircraft to cloud" and "Download all aircraft from cloud" button. Same for routes. I use SkyDemon on the PC for planning, in the tablet for flying only.

A slightly techie solution to what I think you are trying to achieve (?)...... 
For Android/PC/Mac I have used Dropbox / Dropsync to keep them in-sync.
Simply a case of syncing the \sdcard\Skydemon\ directory on the Android with c:\users\<username>\documents\SkyDemon\ on the PC.

This involves a little bit of extra syncing on the PC (between the Dropbox folder and the Skydemon folder) as SkyDemon doesn't appear to allow you to configure where it keeps it's stuff and won't work with a junction point, but on the Mac / Android it's all straight forward.

Perhaps if SkyDemon allowed you to configure where the SkyDemon data directory/folder was located, then people could use (or not use) their cloud storage synchronisation provider of choice..... albeit that doesn't solve for iPad.
