I have a Phonegap app that uses filesystem API to save file on device filesystem.
On startup the app requires some filesystem space with window.requestFileSystem but runtime it's possible to download other files and I can't predict the total amount of needed disk space.
The idea is to check the space available before download begins and if the space is not enough then trigger a message to user.
Is there some method with Phonegap to check remaining free space?
Phonegap does not provide this feature. The solution is to create yourself a phonegap plugin to check the space available.
