Check if file is already open

Question

I need to write a custom batch File renamer. I\'ve got the bulk of it done except I can\'t figure out how to check if a file is already open. I\'m just using the java.

Answer 1

org.apache.commons.io.FileUtils.touch(yourFile) doesn't check if your file is open or not. Instead, it changes the timestamp of the file to the current time.

I used IOException and it works just fine:

try 
{
  String filePath = "C:\sheet.xlsx";
  FileWriter fw = new FileWriter(filePath );                
}
catch (IOException e)
{
    System.out.println("File is open");
}
