Locking a folder or file in Windows isn’t a tricky thing to do. Windows itself gives you all the necessary options. So let’s go ahead and learn about it.

Why you may need to Lock a File or Folder?

There are many reasons why you may feel a need to lock a file or folder. The most common reason is that you share your computer with others. Alternatively, you want to safeguard your files or folders and prevent them from being accidentally deleted. Or if you believe your PC is at risk of getting hacked, someone might steal sensitive information from you.

Locking a file or folder can help you control access to the data and ensure that it is not modified or deleted accidentally or intentionally. It is also helpful in cases where you need to ensure data integrity is maintained.

Windows comes with a built-in option to lock a file or folder. The feature is known as File encryption. Encrypting a file or folder with Windows ties the encryption to your account. This means that when you are logged in, the operating system automatically decrypts the files for you. However, if someone logs in using a different account, they will not be able to access files that were encrypted using your account.

In Windows 11, things have changed. As you can see in the above image, while it is tied to the user account, there is no option for a recovery certificate. The certificate is not generated at all.

How To Open Or Run A Jar File On Windows 11/10

What is Java executable JAR file?

A JAR file is an archiving format that not only stores directories and source files and can also be run as executable files. Such Java ARchive files can contain Java class files that will run when the JAR is executed.

While Archiver tools like 7-Zip can extract content from JAR files, but doing that is pointless – we need to execute the files just as we run the EXE files.

How to run a JAR file in Windows 11/10

Since Java or JAR files can’t run on Windows on their own, you need to install the Java Framework or what is popularly called Java. That said, Java files can be dependent on a particular version of Java. So the steps you need to take to open JAR files on Windows 11/10 are:

Download and install Java.

Set the System path

Run the JAVA file

Set Java file association

Establish a file association with Java runtime.

1] Download and install Java Framework

To run a JAR file on Windows, you need to install Java on your system. Go to Java Download Page, and install it. The default will install the latest version only. However, if your JAR file needs a different version of Java, you can download it from here.

Sometimes, an existing older version of Java can cause an issue. So, if you are facing such a problem, make sure to remove the older version first. Use the official Java Remover tool to get rid of it. Then install the latest version.

2] Set System Path for Java

Next, you need to set the JAVA_HOME path. It ensures that any JAVA file you run can find the necessary libraries for the program. You can also use the command line to echo the Java path to determine if it is correct.

3] Run a Java or JAR file

If you have a JAR file which is not running on its own, then you can use java JDK to run it. Open Command Prompt, and type java -jar name_of_jar_file.jar. It will execute the JAR file automatically.

4] Set the Java or JAR file association

The last step is to establish a file association with Java runtime. It will make sure that every time you run, you are not asked to select a program that can execute it.

Select ‘Choose another app.’

And then choose Select app from the computer.

You should see ‘Java(TM) Platform SE binary’ listed in this context menu but don’t select it.

Locate the file which can run the JAVA or JAR file which is available in the path we suggested above.

Make sure to check the box which says, “Always use this program.”

Once done, all future JAR files will automatically open with Java run time library. You should see the Java icon for all of these files.

How run Java JAR from command line?

You’ll need to use the java command to run a .jar file

If you don’t have java installed, you can fix that by installing the default-jre package.

How To Reduce Video File Size In Windows 11/10?

The way in which videos are made and shared these days have come a long way. Unless you are a professional YouTuber, high video qualities like 2K, or 4K can seem wasteful and a bit of an overkill, since most videos are used for casual recreational and sharing purposes. In a case where you do come across a video that is too big to be shared or uploaded, you may want to reduce its size. So today, I’ll be suggesting some hassle-free ways in which you can do so. I will be discussing freeware as well as a free online tool.

What impacts a video’s size?

The two most common ways in which you can reduce a video’s size without impacting its quality is by either trimming the footage down or removing audio from the video. You can bring your video’s resolutions down but that is going to take a toll on its quality, although tools and software try their best to make the impact as minimal as possible. The resolutions that you choose to go with largely depend on the device that your video will be broadcasted on. The bigger the screen of your device, say television or a home projector, the higher the resolutions you would need. So, one should make modifications to their videos accordingly.

There are several other factors that can play a role in the varied video sizes like video codec and the bitrate. Video bitrate is the amount of data that is used by a video per second. Different videos require different bitrate to stream without losing their quality, depending on their resolution and frame rates. The video codec is used to encode a video and compress its data. Different codecs provide different compression ratios, depending on the contents of the video. For example, the H.265 codec offers a 50% better compression ratio than the H.264 codec.

How to reduce video file size in Windows 11/10

You can reduce video size without losing quality. Using this free video compressor software or online tool you can make video size smaller.

ShotCut free video compressor software

ShotCut is a full-fledged video editing tool used by people far and wide to efficiently cut down on the size of their videos. In order to edit a video on ShotCut, you have to follow the steps mentioned below:

Download & install ShotCut, open it and import a video file using the ‘Open File’ option.

Using an H.264 profile is good enough to cut down on the video size without giving up too much on its quality, and it is what ShotCut itself claims to have done the job for most of its users.

It is in the export settings that you will find options to compress your videos. You can play around with the resolutions and the aspect ratios. You should keep in mind that you make proportionate changes to your configurations unless you want a distorted video.

Changing the output automatically modifies the attributes of the video, suppose you shift from HDV (1080p HD film at 25 fps) to HDV (720p HD film at 29 fps). Your FPS and resolution will change automatically, and so will your corresponding size. Going smaller than the preset resolution, however, will require you to calculate the appropriate dimensions manually.

VideoSmaller free video compressor online tool

Compatible with both Mac and Windows, VideoSmaller is a clean, easy-to-use video compressing tool. The first thing you’ll notice is that it first offers you to use a lower compression level on the video you upload. This would maintain the best quality but won’t reduce the size as much.

Alternatively, you can choose to scale your video. The option to do so is right below the low compression setting, in the form of a dropdown with all possible dimensions. This would impact your video quality, the significance of the impact would depend on how much you choose to scale it back, but it would reduce the file size considerably.

On the bottom is an option for you to rid the video of any sound. This, as mentioned above, has bearings on the file size. So, if your video is something that isn’t in any need of audio, you can check this setting too. On the window where you can upload your video is a warning that VideoSmaller can only take videos up to 500MB, but this isn’t something to be worried about, because it takes hours and hours of footage off of, say, a smartphone, to rag up 500 megabytes. VideoSmaller also claims to keep your uploaded videos off of its cloud, i.e., any video you upload will be removed from its servers a few hours after your work with it is done.

However, not all images have the location info in the description properties. Some will show an empty description in the Details tab.

If none of the methods above work to show the location info of the image, you can try to use Google Reverse Image search.
