Since Unix reads only '/' for folder structure and windows takes both '\' ,'/' .Is there a way to check if dir exists for both in Java? if folder structure has '\' and we use --> 'f.isDirectory()' , the Unix doesn't read the folder structure. Thanks in advance.

    Does this answer your question? [Platform independent paths in Java](https://stackoverflow.com/questions/3548775/platform-independent-paths-in-java) – Martheen Jul 28 '20 at 06:06
  • no,it doesnt really help, thanks anyways – Noobie Jul 28 '20 at 06:09
  • "If the folder structure has \ ...". Well make sure it doesn't have \ before you try. For example by converting them. – Kayaman Jul 28 '20 at 06:36
  • @Kayaman - I am trying to unzip a file which has folders, files seperated with "\" , so it gets unzipped fine in windows and not in Unix – Noobie Jul 28 '20 at 13:40
  • @Noobie zip files are platform agnostic. If you've managed to somehow create a problem with zip files due to the path separator, you're doing something more complicated than it needs to be, and wrong. – Kayaman Jul 29 '20 at 06:26
  • Could you post the code that you are having a problem with, otherwise it is hard to help you. – DuncG Jul 29 '20 at 08:54
  • Very good question. I struggle with this my self. Please let me know if you found a solution. Those who gives negative credit are not reading what you actually asked. It's simple and clear. – Lars Hansen Aug 01 '22 at 09:11

You could look into using the Path API from java.nio.file:

Path rootDirectory = Path.of(System.getProperty("user.home")); // Let's say /home/noobie
Path subDirectory = rootDirectory.resolve("sub"); // home/noobie/sub
Path subSubDirectory = subDirectory.resolve("subsub"); // /home/noobie/sub/subsub
Path subSubDirectoryMethod2 = rootDirectory.resolve("sub").resolve("subsub"); // /home/noobie/sub/subsub

This API works regardless of platform. To check if a path is a directory you can do:

boolean isDir = Files.isDirectory(path);

I found this post, it mentions the difference between Linux and Windows and how to fix it with File.seperator

File.separator or File.pathSeparator
