Directories operations

    +
  1. +

    +To create directory you can use getDirectory method. +

    +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getDirectory("ert",{create:true},function(dir){
+     console.log('Created dir: '+dir.name);
+  })
+});
+

    -Description. +The output: 

    -//////////////////// some code
+Created dir: ert
+
    +If options is {create:false} or null entry of existing directory will be return in successCallback. +
    2. + +
  2. +In a similar way, you can create a file. To achieve that you can use getFile method. +Also if options is {create:false} or null entry of existing file will be return in successCallback. +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getFile("qa.txt",{create:true},function(file){
+       console.log('Created file: '+file.name);
+ });
+});
+
    +

    +The output: +

    +
    +Created file: qa.txt
+
    +
    3. + +
  3. +To achieve delete a directory and all of its contents, you can use removeRecursively method. +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getDirectory("testDirectory", {create:true},
+   function(directoryEntry) {
+     directoryEntry.removeRecursively(function() {
+       console.log("success");
+     });
+ });
+});
+
    +

    +The output: +

    +
    +success
+
    +
    4. + +
  4. +To read entries you have to create reader first, you can use createReader method. +
    +requestFileSystem(TEMPORARY, 100, function (entry) {
+ entry.root.getDirectory("MyDocument", {create:true}, function(dirEntry) {
+      var directoryReader = dirEntry.createReader();
+  });
+});
+
    +
    5. + +
  5. +Having directoryReader you can read the next block of entries from this directory.Please use readEntries method. +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ var a = fs.root.createReader();
+ a.readEntries(function successCallback(entries) {
+   console.log("success");
+ });
+});

    The output: 

    -///////////////// some output
+success

Entries operations

+
    +
  1. +

    +To look up metadata about entry, you can use getMetadata method. +

    +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getMetadata(function (metadata) {
+   console.log("Last modification time: " + metadata.modificationTime);// get metadata successfully
+ });
+});
+
    +

    +The output: +

    +
    +Last modification time: Fri Jan 02 2015 03:58:08 GMT+0900 (KST)
+
    +
    2. + +
  2. +

    +To move an entry to a different location on the file system, you can use moveTo method. +

    +
    +successCallback = function(entry){console.log('Full path to the moved file: '+entry.fullPath)};
+requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getDirectory('testDirectory', {create:true}, function(direntry) {
+   fs.root.getFile("aa.txt", {create:true}, function(fileentry) {
+     console.log('Full path before move: '+fileentry.fullPath);
+     fileentry.moveTo(direntry,'newname.txt',successCallback);
+   });
+ });
+});
+
    +

    +The output: +

    +
    +Full path before move: /aa.txt
+Full path to the moved file: /testDirectory/newname.txt
+
    +
    3. + +
  3. +

    +To copy an entry to a different location on the file system, you can use copyTo method. +

    +
    +successCallback = function(entry){console.log('Full path to the copied file: '+entry.fullPath);};
+requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getDirectory('testDirectory', {create:true},
+   function(direntry) {
+     fs.root.getFile("test.txt", {create:true},
+       function(fileentry) {
+         fileentry.copyTo(direntry,'newname.txt',successCallback);
+       }
+   );
+ });
+});
+
    +

    +The output: +

    +
    +Full path to the copied file: /testDirectory/newname.txt
+
    +
    4. + +
  4. +

    +To look up the parent DirectoryEntry containing this Entry, you can use getParent method. If this Entry is the root of its filesystem, its parent is itself. +

    +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getParent(function (entry) {
+   console.log("success");
+ });
+});
+
    +

    +The output: +

    +
    +success
+
    +
    5. + +
  5. +

    +To deletes a file or directory, you can use remove method. It is an error to attempt to delete a directory that is not empty. It is an error to attempt to delete the root directory of a filesystem. +

    +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getFile('test.txt', {create: true}, function(fileEntry) {
+   fileEntry.remove(function () {
+     console.log("success");
+   });
+ });
+});
+
    +

    +The output: +

    +
    +success
+
    +
    6. + +

    +To return a URL that can be used to identify this entry, you can use toURL method. +

    +
    +requestFileSystem(TEMPORARY, 100, function(fs) {
+ fs.root.getDirectory('testDirectory', {create:true},
+   function(entry) {
+     var url = entry.toURL();
+     console.log('URL: '+url);
+ });
+});
+
    +

    +The output: +

    +
    +URL: file:///home/owner/apps_rw/WfigBlWDyf/tmp/testDirectory/
