No this is not possible I’m afraid we had the same problem. You need to create a placeholder.txt file in each empty directory if you want the precompilation tool to generate these empty folders. Failing that you can create a command line app that will create the folders in your post build events (but only … Read more
You use m + a and put a trailing / on the name of the child node you want to create. E.g., m + a + foo creates the file foo. m + a + foo/ creates the directory foo.
You should use the secondary constructor for File to specify the directory in which it is to be symbolically created. This is important because the answers that say to create a file by prepending the directory name to original name, are not as system independent as this method. Sample code: String dirName = /* something … Read more
Back in the MS-DOS days, “con” had a special meaning. It referred to the console, and allowed you to treat it like any other file. For example, you might create a new text file by typing copy con new.txt. Then you could enter your text and hit ^Z when finished. The thing is, you can … Read more
Charles’ answer is good, but can be improved upon to increase speed and efficiency. Each item produced by os.walk() (See docs) is a tuple of three items. Those items are: The working directory A list of strings naming any sub-directories present in the working directory A list of files present in the working directory Knowing … Read more
ZipOutputStream can handle empty directories by adding a forward-slash / after the folder name. Try (from) public class Test { public static void main(String[] args) { try { FileOutputStream f = new FileOutputStream(“test.zip”); ZipOutputStream zip = new ZipOutputStream(new BufferedOutputStream(f)); zip.putNextEntry(new ZipEntry(“xml/”)); zip.putNextEntry(new ZipEntry(“xml/xml”)); zip.close(); } catch(Exception e) { System.out.println(e.getMessage()); } } }
After some trial and error and observing the results (in other words, I hacked it), I got it to work. Quotes ARE required to use a path name with spaces. The trick is there MUST be a space after the path names before the closing quote…like this… robocopy “C:\Source Path ” “C:\Destination Path ” /option1 … Read more
Try this,to retrieve all files inside folder and sub-folder public static void main(String[]args) { File curDir = new File(“.”); getAllFiles(curDir); } private static void getAllFiles(File curDir) { File[] filesList = curDir.listFiles(); for(File f : filesList){ if(f.isDirectory()) getAllFiles(f); if(f.isFile()){ System.out.println(f.getName()); } } } To retrieve files/folder only public static void main(String[]args) { File curDir = new … Read more
You can check if a directory is empty using find, and processing its output: #!/bin/sh target=$1 if find “$target” -mindepth 1 -print -quit 2>/dev/null | grep -q .; then echo “Not empty, do something” else echo “Target ‘$target’ is empty or not a directory” fi That is: Use find to find the first filesystem entry … Read more
Ruby now has Dir.empty?, making this trivially easy: Dir.empty?(‘your_directory’) # => (true|false) In Rubies prior to 2.4.0 you can just get a list of the entries and see for yourself whether or not it’s empty (accounting for “.” and “..”). See the docs. (Dir.entries(‘your_directory’) – %w{ . .. }).empty? # or using glob, which doesn’t … Read more
