How is the checksum

Many users who often download something from different sharing services, sooner or later wondering about how to learn figure called "checksum file"?It is necessary to find out in some cases.For example, when you run the downloaded app ever issued checksum error.In this article we will study in detail how to find out this information.

So, first you must enter the folder where the file (s), the checksum which we are interested.This is done using the file manager, which is all too familiar.It is called "Total Commander".Use the disc or drop-down lists that are on panels (whatever you like), you must switch to the drive, which is the desired directory.The method of successive change directory you should find you are interested in a folder.

When you open this folder, you will see the contents (files and subfolders).With the help of a manipulator or arrows keys to control the cursor, you must move the marker up or down the list.The interests of the file or files, press the «insert».This action will highlight the desired data.

Next you need to display the settings dialog the parameters by which to calculate the checksum.To do this, in the main menu of our file manager, select "File" and then click on the "Create a file SFV checksums."

after doing this manipulation, we set the parameters for the calculation of the index file "checksum".In the dialog box, you must activate the check box "MD5" (only in case of the need to obtain results in the form of MD5 hash).By itself, the MD5 algorithm is pretty kriptostoek, so now acts de facto standard when used for civilian purposes, as well as the time of publication on the Web.So, set the switch to the "file is created for each separate SFV file."This is done for each computed checksum is stored in a separate file.Now you need to set the path where the result should be saved calculation and template name.

Then our task is to calculate the checksum of all selected files.Therefore press "OK" button in the previous dialogue and wait until the completion of the processes that shape these files checksums.If the total amount of data to be processed is large, all calculations can take considerable time.

After the previous action we begin to study the contents of all files created.This is done by using a text editor or viewer.If the file manager created multiple files, the results, then you open the file that has the same name with the checksum which you are interested.To view highlight the file and press F3.Sets of lines which consist of two parts, and will be the contents of these files.The first part of the line, which will be located before the symbol "star" - the value of the checksum file.And all that will follow after the symbol "star" - the name of the file.
