Java better way to delete file if exists

Question

We need to call file.exists() before file.delete() before we can delete a file E.g.

 File file = ...;
 if (file.exists()){
     fil         


        

Answer 1

Use the below statement to delete any files:

FileUtils.forceDelete(FilePath);

Note: Use exception handling codes if you want to use.

Answer 2

  File xx = new File("filename.txt");
    if (xx.exists()) {
       System.gc();//Added this part
       Thread.sleep(2000);////This part gives the Bufferedreaders and the InputStreams time to close Completely
       xx.delete();     
    }

Answer 3

Use Apache Commons FileUtils.deleteDirectory() or FileUtils.forceDelete() to log exceptions in case of any failures,

or FileUtils.deleteQuietly() if you're not concerned about exceptions thrown.

Answer 4

file.delete();

if the file doesn't exist, it will return false.

Answer 5

if you have the file inside a dirrectory called uploads in your project. bellow code can be used.

Path root = Paths.get("uploads");
File existingFile = new File(this.root.resolve("img.png").toUri());

if (existingFile.exists() && existingFile.isFile()) {
     existingFile.delete();
   }

OR

If it is inside a different directory this solution can be used.

File existingFile = new File("D:\\<path>\\img.png");

if (existingFile.exists() && existingFile.isFile()) {
    existingFile.delete();
  }

I was working on this type of function, maybe this will interests some of you ...

public boolean deleteFile(File file) throws IOException {
    if (file != null) {
        if (file.isDirectory()) {
            File[] files = file.listFiles();

            for (File f: files) {
                deleteFile(f);
            }
        }
        return Files.deleteIfExists(file.toPath());
    }
    return false;
}
