If this abstract pathname does not denote a directory, then this method returns null. On some platforms it may be possible to start the Java virtual machine with special privileges that allow it to modify files that disallow write operations. The object, if any, will reside on the partition named by some ancestor of the absolute form of this pathname. I think the file part is implied. Returns: The number of available bytes on the partition or 0L if the abstract pathname does not name a partition.

Returns: true if and only if the operation succeeded; false otherwise Throws: SecurityException - If a security manager exists and its SecurityManager. For better understanding, Let's understand with the help of some code separator: Platform dependent default name-separator character as String.

SCEGLI DUNQUE LA VITAMINA
|Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists.
On some platforms it may be possible to start the Java virtual machine with special privileges that allow it to execute files that are not marked executable. On UNIX systems, the hash code of an abstract pathname is equal to the exclusive or of the hash code of its pathname string and the decimal value Note that the Files class defines the delete method to throw an IOException when a file cannot be deleted.
When should I use one over the other?
When possible, this method checks for write permissions and other operating system restrictions and will therefore usually provide a more accurate estimate of how much new data can actually be written than getFreeSpace.
