Because itĪtomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. Use File.createNewFile() in a loop for writing. One can consider or LinkedBlockingDeque based on requirement. A read operation just gets the latest filename from this collection and work with it. ![]() The watch service (or similar process) can store the filename of the (latest) file created in the folder to this collection. Using a collection to retrieve latest file:Ī thread-safe collection can be used to store the filenames (or file path) and retrieve them LIFO (last-in-first-out). Note there is no locking mechanism involved if one is using these APIs. I think using the above APIs and methods one can create an application to track the latest files created in a specified folder and perform a required action. The following APIs allow creating and reading a custom file attribute: .UserDefinedFileAttributeView and Files.getFileAttributeView(). This unique attribute value can be associated with a file to identify if its the latest. The attribute allows defining as key-value pair. This gives a chance to be more specific about what is the newest file.Īlso, there is an option to create a custom user-defined file attribute for any file. This can be extracted as of type .FileTime which is in millis or can be a more specific (this allows nanosecond precision). The file already has a created time attribute ( .BasicFileAttributes). ![]() ![]() Each time a new file is created the file creating an event is triggered and the process allows do some user-defined action. In this scenario create a watch service to track new files created in the specific folder. This folder locker for Windows 10 allows you to protect unlimited folders. WatchService API allows tracking file operations (create, modify and delete file) in a specified directory. LocK-A-FoLdeR is a free tool that can password-protect or hide and lock folders. It is a better way than obfuscation.It makes a Native ClassLoader by modifying the source of OpenJDK, could encrypt the classes that you want to protect by AES and parse them in their custom-JRE.You can publish your software with the JRE and distribute your software safety.
