Check files and folder last time accessed in PowerShell

How to check last time a file was accessed?

How to check last time a folder was accessed?



When files and folders are just sitting on a shared folder and just occupying space for an unknown reason, such questions will easily pop.

If there's a need to check files and folders, last write time or last accessed time PowerShell can be very handy.


PowerShell codes below will be able to check files and folders, for last write time or last accessed time.

Code below is from Technet:
http://technet.microsoft.com/en-us/library/e811c7ac-c793-4dc2-82a0-92d08b0f660b

$(Get-Item c:\scripts).lastaccesstime

It will check the last access time for the specified parent folder path.

Code below will list all the:

  Folder and Sub folders plus last write time for each folder. (list folders only)

Get-ChildItem -Recurse "D:\powershell scripts"  | ?{ $_.PSIsContainer } | Select-Object FullName,lastwritetime

Code below will list all the:

 Files and folder plus last write time for each folder and files. (folders and files)

Get-ChildItem  -Recurse  -Path "D:\powershell scripts\"  $_.PSIsContainer|  Select-Object FullName, LastWriteTime

Below code will list all the:

 Files in every folder, which includes LastwriteTime and its file name. (files only)

Get-ChildItem -Path "D:\powershell scripts" $_.LastWriteTime -Recurse

Folder name has space in between, need enclosed path in quotation marks.


List all directories display result in descriptive format:

Get-ChildItem "D:\powershell scripts\" -Recurse | where {$_.PSIsContainer -eq 'Directory'}


To when was the last time a file was modified or written, for example you have a document or a file that is shared and the file needs to be updated constantly. But you are not sure whether file is being updated or modified, PowerShell can help to check the file properties when was the last time it was written or modified.


(Get-item C:\Users\Administrator\WIP_Document\Sales_Doc_Input.docx).Lastwritetime


Sample output will be like this:
Friday, November 24, 2017 7:16:54 AM

Then you can always set a script and send the output to yourself or to anyone who should receive the email.


Cheers!!! Till next time!!!

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.
