I basically want to make a watch service (or something like it) that checks if a file has been closed and instantly remove that file if it did close(finished executing).
How I can achieve this? please give me a cmd commands or some code(i prefer Java).
Ok, this should not be hard to do, if you google a bit you find a Java-File Method called file.canWrite()
which basically returns if a file is locked by an other program or so.
So codewise what you could do is something like this.
boolean isDeleted = false;
File f = new File (// Put your file here);
while (!isDeleted) {
if (f.canWrite()) {
f.delete();
isDeleted = true;
} else {
try {
Thread.sleep(10); // Throws Exception you need to catch somewhere...
} catch (Exception e) {}
}
}
This code you need to include into some Java-Program. I added a simple Thread.sleep(10)
that your PC does not have to check aaaaaalllllllll the time.
See Check if a file is locked in Java
Other possibility would be trying to rename the file with file.renameTo("some_path.txt");
as this method also returns a boolean whether it was successfull! Just note that you then need to update the file again before removing it.
Last possibility I see is pretty similar to the second one. You try to delete the file by calling file.delete();
If the file still exists you know it was not successful and loop because of that.
