Java – get all absolute paths of files under a given folder

absolute-pathapache-commonsjavajava-7list

I need to hold in memory all absolute paths of file names under a given directory.

myDirectory.list() – retrieves String[] of file names only (without their absolute paths).

Don't want to use File Object since it consumes more memory.

Last thing – I can use apache collections etc. (but didn't find anything useful for that).

String directory = <your_directory>;
File[] files = new File(directory).listFiles();
for(File file : files){
  if(file.isFile()){
    System.out.println(file.getAbsolutePath());
  }
}

This works, and I gotta say I'm confused when you say you don't wanna use File objects, but whatever works, I guess.

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'

Also works if it is already an absolute path:

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'

Linux – How to generate a list of files with their absolute path in Linux

If you give find an absolute path to start with, it will print absolute paths. For instance, to find all .htaccess files in the current directory:

find "$(pwd)" -name .htaccess

or if your shell expands $PWD to the current directory:

find "$PWD" -name .htaccess

find simply prepends the path it was given to a relative path to the file from that path.

Greg Hewgill also suggested using pwd -P if you want to resolve symlinks in your current directory.
