converting ecw italy maps to sqlite

I have all the maps of all provinces of Italy igm 25.000 format ecw. Does any body know how to convert them to oruxmaps sqlite.
Oruxmaps Desktop does not work!

example Sardinia:

Sardegna-ecw-map.zip (1.65 GB)

If anybody converts it to sqlite and uploads it to mega even better.

Hello !
This map is big but we can open and transform it with CompeGPS.
The quality of map is poor but usable.
The only (and easy) format that CompeGPS can use to be Ok with Oruxmaps is .rmap.
Let's go : 2 hours of work for this map (1,8 Go).
By chance the result is the same (1,8 Go).
Then, copy to the phone and try.
Oruxmaps is waiting a moment but map is opened without problem. You must stay at the only level presented.
Conclusion :
The easyest way to use .ecw with Oruxmaps is this one. Maybe you can try to get .jpg (and then to create atlas in another soft) but with the size of the .ecw, Windows is unable to open such size (various Go).
Maybe you can try another soft like Global Mapper to convert .ecw but it's not the same price for the license !

Any other links to these ecw files (for the Alps ...Val D'Aoste, Piemond?). I think the .rmap done with Compegpsland can work fine but better to check the accuracy of the calibration ..). I tried the "online" wms maps with mobac but very poor quality and many "stamps" ...
