Using Java's File.delete() method
(4 answers)
Closed 6 years ago.
I was trying to delete some duplicate files in my folder which is around 230GB. Therefore, I searched for files with the names _2 or _3 and use the
file.delete();
However, it deletes the files that I wasn't expecting it. Can I undo that process or are those files deleted permanantly?
The Files are gone. See this Question below

So, about the workaround, If this was on windows, using recovery tools like "File Scavenger" might help you out.

I have a java program and I want it to be able to print out its location on the computer. For example, if I were to place the program in the Downloads folder, and run it, it would print out the path to the file.
new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation()
.toURI()).getPath();
make sure to change the Myclass.class stuff
then system.out.println(File)

Access file in jar file?

I am currently coding a server-panel which will be able to configure plugins and so on.
The only problem I currently have is, I want to get the plugin.yml from inside the jar file.
Is there an API or anything out there, which can get this file decompiled and then read the plugin.yml????
The plugin.yml gets put into the .jar. If you opened the .jar up with something like winrar you can access the file.

Check if file is already open

Is it somehow possible to test if a java.io.File is currently open in another process by any process ? I am using Java 7 and target platforms are Linux/Windows/Mac.
There is no easy way in Java to go about this that will work reliably across different platforms. Depending on what you're trying to do, you might be able to patch together a series of try/catch statements which ostensibly work for most cases on most file systems, but you can never have full certainty that the next situation it encounters won't throw it off.
If you do end up going this route you want to ensure that when there is any doubt, it fails fast and doesn't get into a situation where it thinks a file is not open when it really is. My advice would be to see if there is any way you can possibly work around having to do this check.
