How to reduce the use of Chrome
Chrome browser has always been considered one of the most popular browsers and the main RAM killer of computers since its release until now. It doesn’t matter if the RAM capacity of your system is 4 GB or even 32 GB and more; In any case, by opening Chrome, you will dedicate most of the RAM capacity to Chrome.
Although Google has always been trying to optimize the use of Chrome and periodically improves the stability and consumption of hardware resources of this browser with frequent updates, RAM consumption is still one of the biggest problems for users when using Chrome.
This issue becomes more pronounced when you connect your Google account to Chrome to sync information, extensions, and history, and at this time you will see that at least half of the RAM capacity is easily allocated to this browser.
In general, it is inevitable that a large part of the system resources will be used to use this browser, but with solutions, this effect can be greatly reduced, especially in the case of RAM consumption.

Enable Memory Saver in Chrome
Nearly two years ago, Google introduced the Memory Saver feature to reduce Chrome’s RAM consumption. This feature intelligently disables tabs, add-ons, and other processes that remain unused for a while and do not refer to them, deletes their data from the RAM, and has a significant impact on the RAM consumption of this browser. To enable this feature:
- Enter Settings from the three-dot option at the top of the screen.
- Search for a Memory saver in the search bar above.
- By activating the RAM saver, three levels, Moderate, Balanced, and Maximum, will be displayed, and by choosing each, you can determine the period of time for the tabs to be disabled. By selecting Balanced, the tabs will be disabled after a normal amount of time of inactivity. If you select Moderate, the tabs will be disabled for a longer time, and with Maximum, they will be disabled for a very short time after leaving.
If your RAM fills up quickly and slows down the system, use the Maximum option; However, closing unused tabs is a more logical solution.
If your RAM is not affected much by Chrome, we recommend leaving the setting on Balanced so that when the tab returns and activates, less time is spent on reloading the page and refreshing the cache, thus reducing the processing load.
Prevent tabs from being disabled for a specific site in Chrome
If you have opened an important site that has certain information or is involved in a process that is lost if the tab is disabled, you can prevent it from being disabled by adding the address of this site to the list of exceptions and keeping it open all the time.
- In Chrome settings, from the top search bar, search for inactive.
- Click on the Add option in the Always keep these sites active section.
- You can choose your desired site from the open tabs or enter the desired website address manually from the Add Sites section.
Close unused and high-use tabs
Perhaps Chrome is always accused of high RAM consumption, but the user himself can also be guilty in this case; Therefore, it is better to manage your open tabs and if you are one of those people like me who thinks you should keep tabs open to refer to them every hour or day, you will never see the empty half of the device’s RAM.
For more convenient RAM management, Chrome allows you to see the RAM consumption of each tab by hovering the mouse over the tabs, and thus you can make an easier decision by closing the tabs that are consuming the most RAM.
If you don’t see the RAM usage information by hovering over each tab:
- Open Settings and enter Appearance from the left bar.
- Activate the Show tab memory usage option from the Tab hover preview card section.
Remove or disable unused plugins
Chrome is not just a browser and provides a platform for running various applications and extensions so that as a multi-purpose software, various tools and facilities can be used. This browser has a lot of codes and many complications, part of this complexity is due to the existence of many features and facilities, and most importantly, the infrastructure of the ChromeOS operating system is based on Chromium.
Chrome extensions are so wide and diverse, and among them, there are useful tools that there is rarely a situation where the user of this browser does not install an extension; But sometimes the number of installed add-ons becomes so large that the user loses track of the number and does not notice the increase of add-ons that may have been used only once.
Therefore, if you are one of the people who have many extensions in Chrome, it is better to fix this section and help increase the speed of Chrome and thus reduce its RAM consumption. For this:
- First, through Chrome’s Task Manager, check which extensions occupy the most RAM; To do this, press Shift+Esc.
- Click the Memory footprint tab a few times until an upside-down triangle icon appears next to it.
- Tabs, processes, and add-ons will be shown in order of RAM consumption, and in this way, you can identify the most consuming add-ons.
- Click on the three dots option from the top menu and click on manage extensions from the Extensions section.
- On the add-ons page, turn off frequently used or underused items or remove them completely from Chrome by clicking Remove.
Disable Preload Pages
Chrome has a feature that preloads some sites and pages before the user requests to speed up the page-loading process when the user wants to enter a site.
This feature will be useful for people who have weak internet and it even reduces the processing load of the processor to a great extent, but it will lead to an increase in RAM consumption another way to prevent this is to turn off the mentioned feature:
- In the Chrome settings, search for Preload from the top toolbar and turn off the Preload Pages option.
- You can also balance the level of preloading pages by Chrome and enable Standard Preloading instead of Extended Preloading.

Close Chrome completely and disable background activities
Sometimes, by closing the Chrome window, the processes of this browser do not stop completely and Chrome remains open in the background so that it can be opened faster in the next execution of Chrome. Of course, some extensions and applications that do not deal with tabs and operate independently of Chrome can lead to Chrome’s activity in the background and, as a result, increase RAM consumption.
If you don’t want this app to keep running in the background when you’re not using Chrome:
- Open the settings and enter System from the left menu.
- Turn off the Continue running background apps when Google Chrome is closed option.
In this article, we explained the most important tricks to reduce Chrome consumption; However, with some initiatives, it is possible to reduce Chrome’s RAM consumption even more. If you know or have tried a specific method or trick that has been fruitful and effective for you, share it with us in the comments section.

How to hide a file or directory in Linux?
Most of us have files on our computer or laptop that we don’t want other people to see. If your system uses a Mac or Windows operating system, you can use various tools to hide different files and folders or even encrypt your favorite files to better protect your privacy. In this article, we will talk about how to hide a file or directory in Linux.
In Linux computers and laptops, like Windows and Mac, you can hide your favorite files and directories from the view of others both through the terminal of the operating system and by using some tools that are very easy to use. In the following, we will introduce some efficient methods to hide files and directories in Linux.
Hide files and directories through the terminal
The easiest way to hide various files and directories in Linux is to use the Linux terminal or the Linux graphical environment (GUI).
- Open a Linux terminal window by pressing Ctrl+Alt+T.
- In the terminal, type the following command:
Note: instead of sync.ffs_db, you must enter the name of the file you want and then type the file name again with a dot (.) at the beginning.
To hide the file through the graphical environment (GUI) of Linux, proceed as follows:
- First, right-click on the desired file and click on the Rename option.
- Put a dot (.) at the beginning of the file name.
- Open and close the file once to apply the changes and hide the file.
Hide files in an image
Although hiding the file and directory in Linux by changing the file name seems to be a simple and fast method, but equally, it becomes easy for people who are a little familiar with the Linux environment to access this file. Therefore, we suggest that you go for a better method.
Data encryption or steganography is a method of hiding information in a normal image file, which, like the first method, has almost simple steps, but unlike it, it really hides the files you want from anyone’s view, and you can even hide them after hiding them. Delete the original file in the image irretrievably. In the following, we will teach the steps to hide the file and directory in an image file using the Linux terminal.
- Open the Linux terminal and create a new folder (directory) using the following command.
Note: instead of newdir, enter your desired name for the new directory.
- Copy or move the image file (PNG or JPG) you want to use to hide your desired file into the new folder you created.
Important note: sometimes, depending on the size of the files or the number of files you want to hide in an image, you may need to use a large image so that you have enough space to store the files inside the image.
If you want to hide multiple files, it is better to compress them into one zip file. To compress files in Linux, you must first create a new folder.
- To create a new folder inside the folder you have already created, enter the following command in the Linux terminal:
Note: instead of tmp, you must type the name of the folder you created in the previous step and enter your desired name for the new folder instead of newdir.
In this tutorial, we created a main folder named Images, which contains an image named MainImage.png and a subfolder named FileToHide. This subfolder contains all the files we want to hide.
- To compress your files into a zip file, run the following command in the Linux terminal:
Note: The r- code in the above command includes all the subfolders in the specified folder in the compressed file. In this command, instead of secret.zip, replace the desired name; You should also enter the name of the folder where you have saved all the files you want to hide instead of FileToHide.
To hide the zipped file in your desired image, run the following command in the Linux terminal:
Note: In this command, MainImage.png is our main image file and secret.zip is the name of the zip file that contains all the files we want to hide. In fact, we redirected these two files to a new image file called secret.png. Be careful that the names of MainImage and secret (in both files with PNG and zip extensions) should be replaced with the names you want.
- After running this command, if you want to see a list of all the files in the folder, use the ls command. In this directory, you will see the file name of the new image you created.
- To access files hidden in an image file, use the following command to extract the zip file from within the image:
Note: replace secret.png with the name you chose for the image file containing the secret files .
- When you run the ls command , the root folder containing the files you zipped will be displayed.
- In this case, if you want to see the original files, enter the following command in the terminal:
Delete the original file after hiding it in the image
Sometimes you may want to delete the original version of the file after hiding the sample files you want in an image file. You can use the shred command to do this. This command replaces the file value with a specific value when the file is deleted. For example, we can set the file value to zero when deleting a file.
- For this purpose, after opening the Linux window, run the following command:
By default, these files are overwritten three times (meaning rewriting new information, without the ability to recover previous information). This amount is usually enough, but if you want to overwrite the file more often, you only need to enter the command as follows and replace N with the number of times you want the files to be overwritten.
In this command, the z-code replaces the value of the file with the value zero. Also, the remove- code removes files; Of course, this is done through the shred command itself, but without entering remove- in the shred command, the file removal operation will not be done completely.
