rmdir is my all time favorite command for the job. It works for deleting huge files and folders with subfolders. A backup is not created, so make sure that you have copied your files safely before running this command. RMDIR “FOLDERNAME” /S /Q This silently removes the folder and all files and subfolders.
The answer to that question depends somewhat on the particular Python implementation. To understand what this is all about, pay particular attention to the actual file object. In your code, that object is mentioned only once, in an expression, and becomes inaccessible immediately after the read() call returns. This means that the file object is … Read more
If you are using JDK 7 use the new Files.createTempDirectory class to create the temporary directory. Path tempDirWithPrefix = Files.createTempDirectory(prefix); Before JDK 7 this should do it: public static File createTempDirectory() throws IOException { final File temp; temp = File.createTempFile(“temp”, Long.toString(System.nanoTime())); if(!(temp.delete())) { throw new IOException(“Could not delete temp file: ” + temp.getAbsolutePath()); } if(!(temp.mkdir())) … Read more
Use os.rename(src, dst) to rename or move a file or a directory. $ ls cheese_cheese_type.bar cheese_cheese_type.foo $ python >>> import os >>> for filename in os.listdir(“.”): … if filename.startswith(“cheese_”): … os.rename(filename, filename[7:]) … >>> $ ls cheese_type.bar cheese_type.foo
You should check out Apache’s commons-io. It has a FileUtils class that will do what you want. FileUtils.deleteDirectory(new File(“directory”));
Use File.ReadAllText and File.WriteAllText. MSDN example excerpt: // Create a file to write to. string createText = “Hello and Welcome” + Environment.NewLine; File.WriteAllText(path, createText); … // Open the file to read from. string readText = File.ReadAllText(path);
fileConn<-file(“output.txt”) writeLines(c(“Hello”,”World”), fileConn) close(fileConn)
Python 2.4 and Earlier f = open(“myfile”, “rb”) try: byte = f.read(1) while byte != “”: # Do stuff with byte. byte = f.read(1) finally: f.close() Python 2.5-2.7 with open(“myfile”, “rb”) as f: byte = f.read(1) while byte != “”: # Do stuff with byte. byte = f.read(1) Note that the with statement is not … Read more
In Python 3.2+, using the APIs requested by the OP, you can elegantly do the following: import os filename = “/foo/bar/baz.txt” os.makedirs(os.path.dirname(filename), exist_ok=True) with open(filename, “w”) as f: f.write(“FOOBAR”) With the Pathlib module (introduced in Python 3.4), there is an alternate syntax (thanks David258): from pathlib import Path output_file = Path(“/foo/bar/baz.txt”) output_file.parent.mkdir(exist_ok=True, parents=True) output_file.write_text(“FOOBAR”) In … Read more
From the docs: If no encoding is specified, then the raw buffer is returned. Which might explain the <Buffer …>. Specify a valid encoding, for example utf-8, as your second parameter after the filename. Such as, fs.readFile(“test.txt”, “utf8”, function(err, data) {…});
