When you create a JAR file, the time of creation is stored in the JAR file. Therefore, even if the contents of the JAR file do not change, when you create a JAR file multiple times, the resulting files are not exactly identical. You should be aware of this when you are using JAR files in a build environment. Java File.createFile method. The File.createFile is a method of File class which belongs to java.nio.file package. It also provides support for files. The nio package is buffer-oriented. The createFile method is also used to create a new, empty file. We don't need to close the resources when using this method. It is an advantage. The options and arguments used in this command are: The c option indicates that you want to create a JAR file.; The f option indicates that you want the output to go to a file rather than to stdout.; jar-file is the name that you want the resulting JAR file to have. You can use any filename for a JAR file. By convention, JAR filenames are given a.jar extension, though this is not required.
In Linux, we can create an empty file using ‘touch‘ command. There’s no equivalent command for touch in Windows OS. However, we can still create zero byte files using the command
fsutil
.Create stream from Iterator. Iterators, in Java, are used in Collection Framework to retrieve elements one by one. Spliterator is the key to create the sequential stream. Hence in this method also, Spliterator is used. But in this method, the source of Spliterator is set to an Iterable created from the Iterator.
The syntax of fsutil command for creating a file is: Script debugger 7 0 6 – applescript authoring environment examples.
Below is the command you can run to create a empty text file.
Example: Wi fi crack v1 03.
The above command can be run from a batch file also. It works on all Windows editions: XP, Server 2003, Vista, Windows 7, Server 2008.
‘fsutil‘ command should be run from elevated administrator command prompt. Otherwise, you would get the below error message.
Using echo command
In Linux, we can use echo command also to create empty text files. This command is available in Windows also.
But using ‘echo’ we can’t create empty files. See below.
But using ‘echo’ we can’t create empty files. See below.
As you can see, it has created a file of size 13 bytes.

Fsutil.exe is a built in filesystem tool that is useful to do file system related operations from command line. We can create a file of required size using this tool.
syntax to create a file:
For example, to create a dummy file test.txt, with size as 50MB :
Note that the above command creates a sparse file which does not have any real data. If you want to create a file with real data then you can use the below command line script.
(Run the above two commands one after another or you can add them to a batch file.)
The above commands create a 1 MB file dummy.txt within few seconds. If you want to create 1 GB file you need to change the second command as below.
Explanation:
The first command(echo…) creates the file dummy.txt with 64 bytes.
The second command, runs in a loop for 24 times, and each times doubles the size of the file, by appending it to itself.
