PowerShell - File and Directory Operations

You want to list all files in C:\Projects and its subfolders, but only those modified in the last 7 days. Which command achieves this?

AGet-ChildItem -Path C:\Projects -Recurse -Filter LastWriteTime -gt (Get-Date).AddDays(-7)

BGet-ChildItem -Path C:\Projects -Recurse | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) -and $_.PSIsContainer -eq $false }

CGet-ChildItem -Path C:\Projects -File -Recurse -LastWriteTime (Get-Date).AddDays(-7)

DGet-ChildItem -Path C:\Projects -Recurse | Where-Object { $_.CreationTime -lt (Get-Date).AddDays(-7) }

Step-by-Step Solution

Solution:

Step 1: Filter files modified in last 7 days
Use Where-Object to check LastWriteTime greater than 7 days ago.
Step 2: Exclude directories
Check that $_.PSIsContainer is false to list only files.
Step 3: Verify options
Get-ChildItem -Path C:\Projects -Recurse | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) -and $_.PSIsContainer -eq $false } correctly uses these filters; others misuse parameters or filter incorrectly.
Final Answer:
Get-ChildItem -Path C:\Projects -Recurse | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) -and $_.PSIsContainer -eq $false } -> Option B
Quick Check:
Filter by LastWriteTime and exclude folders = Get-ChildItem -Path C:\Projects -Recurse | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) -and $_.PSIsContainer -eq $false } [OK]

Quick Trick: Use Where-Object to filter by date and exclude folders [OK]
