When I used the File.delete() method to delete a file, where is the deleted file? I am using a Mac and I don't see the file in the Trash. I want to know where the file is being stored at? Or if it is permanently gone.
Thanks,
It's gone. The trash bin is just a temporary place where files are put before being deleted, when you "delete" them through the OS.
In most filesystems, however, deleting a file only removes the pointer to it from the system's list of files. The actual data may sit on the harddrive for a significant amount of time until it is overwritten. There are file recovery tools available that can attempt to retrieve such files, but they are not 100% sucesfull.
The trash in Mac/Linux (or Recycle Bin, in Windows) only work with the specific file managers (Finder, Nautilus/Dolphin or Explorer) where they actually move a file into a temporary folder on the same partition (aka Trash / Recycle Bin), from where it's deleted.
From the core OS's point of you, delete() will permanently delete it.
where the file is being stored?
It isn't. You deleted it. It's deleted.
Calling File.delete() permanently removes the file, without going into the recycling bin or anything similar.
