Suggested April 2024 Verify File Integrity With Free File Integrity & Checksum Checkers

It is always important to verify whether the large file you downloaded is the file you expected to download or not. This is because files may change in some way from the original while downloading. This may be due to corruption, due to errors in the download process. The downloaded files may even possess security-compromising features or include unwanted malicious software such as a virus or malware.

Therefore, no matter what the reason is, you should check the integrity of the files first. You should also check if there is any change from the original form or not. There are various ways by which you can check the original form. For instance, you can check if a file has a digital signature or not or check the hash value of it.

MD5 checksum

The MD5 checksum for a file is a 128-bit value which is unique to the file – something like a fingerprint. It can be used to compare files and their integrity control.

Check the hash value

Some web pages offering programs to download provide a long code called as MD5 near the program link. When you apply a cryptographic hash function to it, a string value is returned which is only valid for that file in the current state. If you download the same file with changed data (at very few places only) from some other website and apply this cryptographic function again, you will observe the value is changed. So, you can easily determine if the file is untouched or not.

Luckily, there are many programs available for Windows that help you calculate the hash value and check if the hash value you have of files matches or not. I am covering some free File Integrity Checkers & File Checksum Integrity verifier tools to check file integrity of downloaded files in Windows using Using MD5 & SHA1 Hashes, by computing MD5 or SHA1 cryptographic hashes for files.

Python Zip File With Example

Python allows you to quickly create zip/tar archives.

Following command will zip entire directory

shutil.make_archive(output_filename, 'zip', dir_name)

Following command gives you control on the files you want to archive

ZipFile.write(filename)

Here are the steps to create Zip File in Python

Step 1) To create an archive file from Python, make sure you have your import statement correct and in order. Here the import statement for the archive is from shutil import make_archive

Code Explanation

Import make_archive class from module shutil

Use the split function to split out the directory and the file name from the path to the location of the text file (guru99)

Then we call the module “shutil.make_archive(“guru99 archive, “zip”, root_dir)” to create archive file, which will be in zip format

After then we pass in the root directory of things we want to be zipped up. So everything in the directory will be zipped

When you run the code, you can see the archive zip file is created on the right side of the panel.

Now your chúng tôi file will appear on your O.S (Windows Explorer)

Step 4) In Python we can have more control over archive since we can define which specific file to include under archive. In our case, we will include two files under archive “guru99.txt” and “guru99.txt.bak”.

Code Explanation

Import Zipfile class from zip file Python module. This module gives full control over creating zip files

We create a new Zipfile with name ( “testguru99.zip, “w”)

Creating a new Zipfile class, requires to pass in permission because it’s a file, so you need to write information into the file as newzip

We used variable “newzip” to refer to the zip file we created

Using the write function on the “newzip” variable, we add the files “guru99.txt” and “guru99.txt.bak” to the archive

When you execute the code you can see the file is created on the right side of the panel with name “guru99.zip”

Note: Here we don’t give any command to “close” the file like “newzip.close” because we use “With” scope lock, so when program falls outside of this scope the file will be cleaned up and is closed automatically.

Here is the complete code

Python 2 Example

import os import shutil from zipfile import ZipFile from os import path from shutil import make_archive def main(): # Check if file exists if path.exists("guru99.txt"): # get the path to the file in the current directory src = path.realpath("guru99.txt"); # rename the original file os.rename("career.guru99.txt","guru99.txt") # now put things into a ZIP archive root_dir,tail = path.split(src) shutil.make_archive("guru99 archive", "zip", root_dir) # more fine-grained control over ZIP files with ZipFile("testguru99.zip","w") as newzip: newzip.write("guru99.txt") newzip.write("guru99.txt.bak") if __name__== "__main__": main()

Python 3 Example

import os import shutil from zipfile import ZipFile from os import path from shutil import make_archive # Check if file exists if path.exists("guru99.txt"): # get the path to the file in the current directory src = path.realpath("guru99.txt"); # rename the original file os.rename("career.guru99.txt","guru99.txt") # now put things into a ZIP archive root_dir,tail = path.split(src) shutil.make_archive("guru99 archive","zip",root_dir) # more fine-grained control over ZIP files with ZipFile("testguru99.zip", "w") as newzip: newzip.write("guru99.txt") newzip.write("guru99.txt.bak") Summary

To zip entire directory use command “shutil.make_archive(“name”,”zip”, root_dir)

To select the files to zip use command “ZipFile.write(filename)”

How File Handling Work In Scala With Eamples

Introduction to Scala File

Scala file handling is quite similar to java. We can use a scala package or we can also use packages provided by java to handle files. We can create, read, write, and open a file in scala similarly we can do in other languages. Scala provides us various methods to create or read, write on file we just need to import proper packages to use those classes, methods, or interfaces. The file is a concept of strong and fetching of our data we can write any lines of data into the file.

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Syntax:

val my_file = new File("your_file_name" )

The above syntax shows how we can create a file in our system. We just need to give the variable and file name by which we want to create the file in the system.

val myfile = new File("demo.txt" )

This will create a file in your system with a specified name.

How File handling work in Scala?

The purpose to use file is that we can easily store and retrieve our data from the file when needed. But to create a file and read from file we must have chúng tôi package import in our Scala Program because in scala we do not have any standards library for writing data to file so for that we need to use chúng tôi So in java file class, we can either pass a file name or a directory name where we want to create a file. This file class has so many different methods which are working internally to handle the file.

So if you want to create a file object we must follow the below steps;

var myfile = new File("file name")

In this, you can give your filename or directory name. This path can be relative or absolute. This file class also maintains the access permission issues when it comes to the security of files to prevent it from external use. Also, this Java File class is immutable that means once created cannot change.

It has many methods. Some are mentioned below:

String getAbsolutePath(): to get absolute path

boolean canExecute()

boolean exists() : File exists

boolean canWrite() : to write

boolean delete() : to delete

boolean equals(Object obj) : compare two objects

boolean canRead() : to read

In the scala, we have a chúng tôi package to handle file events. Also, we can use java package to achieve those same features. Let’s discuss them one by one. Now first we will see how we can write and create a file in scala.

Step 1: To create and write on a file;

import java.io._ val myfile = new File("demo.txt" ) This is the very basic step to start with.

Explanation: In the above line of code, we are creating a file object. File objects have this constructor in which we need to pass the file name. It will create one file with the specified name in the system.

Step 2: This file object is available in the chúng tôi package so we need to import it into our program in order to avoid any errors.

val pr = new PrintWriter(myfile)

Explanation: Now we are using PrintWriter object to parse our file. As the name suggests it has a write a method to write in a file. This is also available inside the chúng tôi package.

Step 3: For this, we need to parse our file into its constructor.

pr.write("We are writing to the file.")

Explanation: PrintWriter has this method to write in the file with specified content.

Step 4:

pr.close()

Explanation: In this step, we are just closing this object.

Below you can find the steps which are required to read data from a file:

val myfile = "demo.txt"

Explanation: In this step, we are just defining the name of the file from which we want to read data.

Step 2:

val src = Source.fromFile(myfile)

Explanation: Now this step is important because here we are using Source class to provide them the file and get the data of the file. It has one method called From File where we need to provide the filename from which we want to read.

Step 3:

for(line<-src.getLines){ println(line) }

Explanation: To read data we must require a for loop in order to iterate over each and every word of the file. Here we are creating an instance of the iterable file which can easily be iterated.

Step 4:

src.close()

Explanation: In this step, we are just closing the source object. It helps us prevent our data from external use.

Operation Create Write Write Method

Write New File() PrintWriter PrintWriter.write()

Operation Read To Get file To get file data

Read Filename Source.fromFile Get lines()

Packages to be imported:

Points to be remembered:

Example to Implement Scala File

Below are the examples of Scala File:

Example #1

In this example, we are creating, parsing, and writing to a file.

Code:

import java.io.File import java.io.PrintWriter object Main extends App{ val myfile = new File("I:\demo.txt" ) val myPrintWriter = new PrintWriter(myfile) myPrintWriter.write("This is our first content to write into a file.") myPrintWriter.close() }

Output:

Example #2

In this file, we are reading from the file that we have created previously. Please import chúng tôi to work.

Code:

import java.io.File import java.io.PrintWriter import scala.io.Source object Main extends App{ val myfile = "demo.txt" val src = Source.fromFile(myfile) while (src.hasNext) { println(src.next) } src.close() }

Output:

Conclusion

Files are used to store our data. In scala, we used two libraries to deal with file handling i.e. chúng tôi and chúng tôi Like any other programming language, we can create, read, and write into a file. The file got created on a particular location if given otherwise it will create into the user folder of our system.

How To Open File With No Extension In Windows 11/10

Every file that we have saved on our computers has a particular extension. The file extension is added at the end of the filename followed by a dot (.). It tells the operating systems about the structure of the file so that the OS could select the right software or application to open that file. You might have seen some files on your computer that do not have any file extension or file type. How do you open such types of files? In this article, we will see how to open a file with no extension in Windows 11/10.

When it comes to opening a file on a Windows OS, there are three ways that a user can try:

Select the file you want to open and hit Enter.

To open a file, you should have the right program installed on your system. For example, if you want to open an Excel file, you should have a program that supports the excel file, like Microsoft Excel, Apache Open Office, Libre Office, etc. If you want to open a PDF file, you should have a PDF reader or a web browser to open the PDF file.

What if you come across a file with no extension? In this case, none of the above three methods work to open that file. To open the files with no extensions, first, you have to identify their extension or type. After identifying their extension, install the right program on your computer to open that file.

If you view the properties of the file with an unknown extension, you will see File as its file extension.

How to open a file with no extension in Windows 11/10

There are some free file identifier tools that let you know the extensions of the unknown file types. We have listed some of these tools below.

How do I enable file extensions in Windows 11?

To show file extensions in Windows 11, you just have to change the view mode in File Explorer. The steps are as follows:

Open the File Explorer.

After selecting the Details view, you will be able to see the file extensions in the Type column.

If you do not want to change the view mode in File Explorer, you can enable the file extension by following the below-listed steps:

Open File Explorer.

Select the View tab and uncheck the Hide extensions for unknown file types option.

After that, Windows 11 will show the file extensions in every view mode you select.

How do I enable file extensions in Windows 10?

The methods to enable file extensions in Windows 10 are the same as in Windows 11 but the steps are a bit different in both of these operating systems. You either have to change the View mode or turn off the Hide file extensions option.

Another way to enable the file extensions is turning off the Hide file extensions in Folder Options. The steps are as follows:

Open the File Explorer.

Now, select the View tab and uncheck the Hide extensions for unknown file types option.

I hope this helps.
