$tempfolders = you put inside the parentheses is your choice. I start with the array indicator ( = I follow it with parentheses to group strings together: Here is where the arrays and variables differ when defining. Just like a variable, I use the equal sign ( =) to define it. They are defined much like a normal variable-they start with the variable ( $ ) indicator followed by the array name: So we change our flowchart to look something like this:Īrrays are a nifty programming feature that groups a number of strings together into one variable, while remaining individual strings. This says, “Look in all folders in this directory with the path structure that matches this.” In my case, this is all of the user profile Local Settings\temp folders.īut this looks very busy, so at Ed Wilson’s suggestion, an array would prevent all the unnecessary jumping around with the Set-Location command. Why is there an asterisk in the middle of the last path? You can use wildcard characters to do this: Remove-Item “.\*\Appdata\Local\Temp\*” -recurse -force Remove-Item “.\*\Local Settings\temp\*” -recurse -force I do the same for the rest of the folders and the complete script begins to take shape: Next I tell the Remove-Item cmdlet to also remove all files in subdirectories with the -recurse switch:Īnd I tell it to select hidden files with the -force switch: Because I do not want to discriminate between different files, I use the asterisk. The question mark ( ?) wildcard stands for one character and the asterisk (*****) wildcard stands for any number of characters. A wildcard character is a special character that represents one or more other characters. The items need to be removed indiscriminately, so I use a wildcard character.

This can be done with the old DOS command Del, but I prefer using the Windows Powershell cmdlet Remove-Item to standardize the script.
Now that I am located in the Windows temp folder, I need to delete the files. I start with the Set-Location command and define the location as “C:\Windows\Temp”: Now that I have defined our locations, I need to define what I want to do.
