Android Question disk size? File attributes?

[boten]

Is there a way to get the total disk size/free space?
something like : TotalDiskSize(File.DirRootExternal ) or FreeDiskSpace(File.DirRootExternal )

also is there a way to get file attributes
something like: IsHidden(File,Dir)

There is no hidden attribute in Android.

thx for size link. still...
If not hidden then:
Using MyFiles (builtin file browser in Samsung) to show storage, lists some folders (usually system folder?) with "dimmed" folder icon. What does it signifies? and how to tell if a folder is "dimmed" or not?

 

[Erel]

Maybe folders starting with . (dot).

 

[boten]

Maybe folders starting with . (dot).

Apparently so. Any significance to the dot or just file browser whim?

The dot makes some apps think there is no file name, just the extension, and ignore it Pictures starting with a . for example, will not show in most photo browsers.
