Download And Install Windows PowerShell If Not Already

Download And Install Windows PowerShell if it is not already installed on your computer

For this project, do the following: 1) Download and install Windows PowerShell if it is not already installed on your computer (see Start Menu > Accessories ). 2) Review the Getting Started information in the Windows PowerShell help file, and study the information in the help file and online resource for basic scripting techniques using Windows PowerShell. 3) Prepare a document to submit your work: A. Use Microsoft Word B. Title page a) Course number and name b) Project name c) Your name d) Date C. Write a Windows PowerShell script that will perform the following functions: a) Search your computer for files ending with a .doc, .docx, .xls, or .xlsx file extension. b) Output the filenames and sizes (in groups by file extension) to a text file named “File_Summary.txt”. The output should also conclude with a total of the number of files and total file size for each file extension. c) Include comments in the script code to document the functionality of the script. D. Paste the script and the file output to your MS Word document.

Paper For Above instruction

In this comprehensive project, the primary goal is to develop a PowerShell script that efficiently searches a computer for specific document and spreadsheet files, categorizes them by type, and summarizes their sizes and counts in an output text file. This task not only enhances scripting skills but also aids in managing disk space and organizing files systematically. The following sections describe the step-by-step process, including setup, scripting, and documentation, culminating in an organized report ready for submission.

Introduction

Windows PowerShell is a command-line shell and scripting language that facilitates automation and configuration management. Its versatility allows users to perform complex tasks through scripting, including searching for files across the filesystem. Before scripting, it is essential to ensure PowerShell is installed and functional; if not, it must be downloaded and installed from official sources. After installation, reviewing basic scripting techniques and help resources prepares users to write effective scripts that are both functional and well-documented.

Setting Up PowerShell

The initial step involves verifying the installation of Windows PowerShell. Typically, Windows 10 and later versions include PowerShell by default; however, earlier versions or custom Windows builds may lack it. Downloading PowerShell from the official Microsoft website ensures access to the latest features and security updates (Microsoft, 2020). Once installed, users should familiarize themselves with the PowerShell help system, which provides guidance on commands, scripting syntax, and best practices (Microsoft Docs, 2023). This foundational knowledge is crucial for developing scripts that are robust and error-free.

Developing the Script

The core of this project is creating a script that searches the entire system—or a specified directory—for files with particular extensions: .doc, .docx, .xls, and .xlsx. The script should group the files based on their extensions and output the filenames and sizes into a text file named “File_Summary.txt”. Additionally, the script must calculate and present the total number of files and accumulated file size for each extension, providing a clear overview for the user. To enhance clarity and maintainability, comments are embedded throughout the script, explaining each significant step.

Script Structure and Logic

The scripting process involves several key components:

  • Defining the search path: the root directory or specific folder where the search begins.
  • Utilizing Get-ChildItem with filters to locate files with the specified extensions.
  • Grouping the files by extension using Group-Object.
  • Calculating individual file sizes using the Length property.
  • Summing sizes and counting files within each group for the summary.
  • Writing the detailed list and summary statistics to “File_Summary.txt”.

Sample PowerShell Script

# PowerShell script to search for specific document files, group by extension, and summarize count and size

Define the path to start the search; here, C:\ is used as an example


$searchPath = "C:\"


Define the output file


$outputFile = "File_Summary.txt"


Initialize the output file


"File Extension Summary Report" | Out-File -FilePath $outputFile -Encoding UTF8


Define file extensions to search for


$fileExtensions = @(".doc", ".docx", ".xls", ".xlsx")


Loop through each extension, find files, and generate report


foreach ($ext in $fileExtensions) {


Get files with current extension


$files = Get-ChildItem -Path $searchPath -Recurse -Filter "*$ext" -File -ErrorAction SilentlyContinue


Calculate total files and total size


$fileCount = $files.Count


$totalSize = ($files | Measure-Object -Property Length -Sum).Sum


Output header for current extension


"`nFiles with extension: $ext" | Out-File -FilePath $outputFile -Append -Encoding UTF8


List each file with its size


foreach ($file in $files) {


"$($file.Name) - $(Format-FileSize $file.Length)" | Out-File -FilePath $outputFile -Append -Encoding UTF8


}


Output summary statistics


"Total files: $fileCount" | Out-File -FilePath $outputFile -Append -Encoding UTF8


"Total size: $(Format-FileSize $totalSize)" | Out-File -FilePath $outputFile -Append -Encoding UTF8


}


Function to format file sizes in a friendly format


function Format-FileSize([long]$bytes) {


if ($bytes -ge 1GB) {


"{0:N2} GB" -f ($bytes / 1GB)


} elseif ($bytes -ge 1MB) {


"{0:N2} MB" -f ($bytes / 1MB)


} elseif ($bytes -ge 1KB) {


"{0:N2} KB" -f ($bytes / 1KB)


} else {


"$bytes Bytes"


}


}

This script demonstrates a systematic approach to file searching and reporting. It uses core PowerShell cmdlets, control structures, and functions to deliver a comprehensive output that categorizes files by type, lists individual file details, and summarizes counts and sizes. Comments throughout the script clarify each step, facilitating understanding and future modifications.

Execution and Output

To execute the script, save it as a .ps1 file, such as "FileSearchScript.ps1," and run it from the PowerShell prompt with appropriate permissions. The output file, “File_Summary.txt,” will contain detailed listings and summaries, which can be reviewed to assess disk space usage or locate specific document files efficiently.

Conclusion

This project emphasizes practical scripting skills and file management techniques using Windows PowerShell. The created script not only automates the tedious task of manual file inventory but also provides valuable insights into storage usage. Proper documentation and organized output ensure the script's usability and ease of understanding for future customization or troubleshooting. Mastery of these scripting principles forms a foundation for more advanced automation tasks and system administration functions.
