B4J Question DirRootExternal

[Roger Daley]

Hi All.

Is there such a thing as DirRootExternal in B4J? File.DirRootExternal gives an Unknown Member error.
In the jRandomAccessFile examples "DirRootExternal" is shown in the code?

Just wondering what is the B4J equivelent for DirRootExternal?

That's probably left over code from porting the examples over to B4J from B4A. DirRootExternal, in B4A, points to the root folder of the "external SD card" (which need not be an SD card, to make things more fun for the developers). There's no such universal equivalent in desktop Java. You can probably store temporary data in sub-folder of File.DirApp unless you're packaging your app into a Windows installer, in which case you'll want to use File.DirTemp or File.DirData, depending on your intent.

There is no DirRootExternal. The documentation will be fixed.

See this tutorial: https://www.b4x.com/android/forum/threads/working-with-files.34672/

In most cases you should use File.DirData.

Thanks Roycefer,
It looks like it will be DirData.
