And, since the WQL escape character is also the backslash, resulting in the double-backslash characters.

To ensure youre in the clear, you should learn how to use PowerShell to delete files.

Windows PowerShell 5.1 or PowerShell 7.0 A script editor such as Visual Studio Code, Atom, or Notepad.

To delete just a single file, you only need to use the command below.

The Get-ChildItem cmdlet targets C:temp with the -Path parameter.

The -File parameter indicates that the only type of item to be included are files.

The output below shows that the code was able to delete files in the top folder; however, it failed to retrieve the files in the sub-folders.

That error is indicative that the path the cmdlet is trying to get to does not exist which is misleading.

The combination of all the characters that make up the nested directory names creates a long path problem.

Instead of specifying the path like this C:temp, use the Unicode version like this C:temp for folders located locally, or UNC Temp if the folder is located in a UNC path.

This example is useful for removing old log files, like those generated by IIS web servers, to free up disk space.

Using the script below, the Name, CreationTIme, and AgeInDays of each file in c:temp is shown.

The value of the threshold the age in days that the file to be deleted must be.

Filter the output to include only files whose CreationTime value is older than the number of days saved in the threshold variable.

Pipe the filtered list of files to the Remove-Item value to perform deletion of those files.

Get-ChildItem -Path path -File Where-Object PSItem.CreationTime -lt (Get-Date).AddDays(-threshold) Remove-Item -Verbose.

To confirm that files newer than 14 days still exist, run the code below to list them again.

Only when youre satisfied with the list of files for deletion, you can finally pipe the collection to the Remove-Item cmdlet.

And support for WMI means that WMI queries and methods can be called from within PowerShell.

Yes, WMI is not just for Visual Basic scripts that admins used in the earlier days of Windows.

The Get-CimInstance cmdlet with the CimDataFile class is used to retrieve the information about the file to delete which is C:Temprandom.txt.

Using WQL requires that you escape some characters including the backslash.
