There is not "free space inside a folder". Folders can be filled with data until the disk is full or if a disk quota for a specific user is reached. You can check the available disk size by:

FileObj      = java.io.File(Folder);
free_bytes   = FileObj.getFreeSpace;
total_bytes  = FileObj.getTotalSpace;
usable_bytes = FileObj.getUsableSpace;

Note that filling a disk to more than 99% (95% is better) might cause a loss of data. If the disk is exhausted, the behaviour is not well defined.
