How to delete files in a folder and its subfolders via command line?

Deleting files is good and bad.

Good because it will free up space and able to get rid of your unwanted files.

Deletion is bad when you accidentally delete a file, and lost everything.

Confident that there was a backup and yes indeed there was a backup that was never tested.

Upon recovery backup is corrupted.

Well life is full of surprises; you got to be ready what mystery life may bring.

There are instances that we need to delete unwanted files.

Not only the file has been there since Windows 95 era, there are files that you keep and you even don’t even know why you’re keeping it.

You forgot what the purpose of the file is and why it was downloaded and besides the file has been dormant for years and years and it’s just taking up space on your hard drive.

When the time comes, you want to get rid of those files that you don’t need.

But there’s a hundred or thousands of it, and it’s not fun to delete them one by one.

If you’re a scripter first thing that will come into your mind, you will make a script and that’s it delete those files.

Script can do the job but I believe in simplicity, if there is a simple way to finish the job the simpler would be the better.

So a one liner command line can do the job to delete files in your folder and subfolders.

Here’s how to do it.

First, if you just want to have a list before deleting the files.

Type this at the command line:

For example you just want to have a copy of all zip files on directory c:\xrar and its subfolders.

Open command prompt.

     DIR c:\xrar\*.zip  /s  > d:\backup\myFileList.txt

Above command line will read the contents of xrar and its subfolders and the list will be written to myFileList.txt.

Before doing any deletion check myFileList.txt and check whether the command executed the way you want it to be.
 
myFileList.txt contains all zip files on that particular folder specified on the command.

NOTE: If myFileList.txt contains other files, which is not a zip file. Please don’t execute command below.

Since you have the list of files on the specified folder path, you are ready to delete.

Having the list of files before deletion will be helpful, if some other time you can’t find the file you just go back to your list and check whether the file has been deleted. Save your time for searching the file.

On this example we will just delete all the zip files on the xrar folder and its sub folders.

The command to do the jobs is:

Open command prompt.

Please be extra careful, when executing delete command and be sure that you don’t need the file and you know exactly what you are doing.

     DEL c:\xrar\*.zip /s /q

Below is an example when I executed the command above: (it deletes the zip files on all the subfolders)
Deleted file - c:\xrar\pencil-0.4.4b-win.zip
Deleted file - c:\xrar\1\pencil-0.4.4b-win.zip
Deleted file - c:\xrar\1\2\pencil-0.4.4b-win.zip
Deleted file - c:\xrar\1\2\3\pencil-0.4.4b-win.zip
Deleted file - c:\xrar\1\2-1\pencil-0.4.4b-win.zip

That’s it no script needed, just a simple command line.

In this example I just use *.zip, you can replace *.doc* to delete all document files or *.xls* to delete excel files. Or any file extension that you wanted.
Just make sure you know exactly what you are doing, deletion is not a joke.



Cheers!! Hope it saves your time by doing the right deletion!!

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided. Why would you need a command line tool if there’s a GUI to check? If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username. If you have remote computers, you need to delegate someone in the remote office or location to check. Or you can just write a batch file or script to automate the task. Here’s the code below on how get computer model, manufacturer and the username. Open an elevated command prompt and type:     wmic computersystem get "Model","Manufacturer", "Name", "UserName" Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.

Notepad++ convert multiple lines to a single line and vice versa

Notepad++ is an awesome text editing tool, it can accept regex to process the text data. If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur.
