Deleting a created file at every iteration - powershell

Question

$getFiles = Get-ChildItem -Path $readDir -File -Include "*.doc","*.docx","*.xlsx"-Recurse | %{
if(($_ -match "\.doc$") -or ($_ -match "\.docx$")){
$Doc = $word.Documents.Open($_.fullname)
$nameDoc = $fileSaveLoc + $_.Name.Replace(".docx",".txt").replace(".doc",".txt")
$Doc.saveas([ref] $nameDoc, [ref] 5)
$Doc.close()
if((Get-ChildItem "I:\temp\").length -ne 0){
$locations = (Get-Item "I:\temp\"), (Get-ChildItem "I:\temp\" -Directory -recurse) | % {
Get-ChildItem -File $_.FullName | Select-String -List -Pattern '^\d{3}-?\d{2}-?\d{4}$' |
% Path
}
if($locations -ne $null){
$locations | out-file "I:\temp\SSN_FILES.txt"
#Get-ChildItem "I:\temp\" -exclude "fullpath.txt","SSN_FILES.txt" | remove-item
}else{
Get-ChildItem "I:\temp\" -exclude "fullpath.txt","SSN_FILES.txt" | remove-item
}
}
}
elseif($_ -match "\.xlsx$"){
$workbook = $excel.Workbooks.Open($_.FullName)
$csvFilePath = "I:\temp\" + $_.Name.Replace(".xlsx",".csv")
#$csvFilePath = $_.FullName -replace "\.xlsx$", ".csv"
$workbook.SaveAs($csvFilePath, [Microsoft.Office.Interop.Excel.XlFileFormat]::xlCSV)
$workbook.Close()
if((Get-ChildItem "I:\temp\").length -ne 0){
$locations = (Get-Item "I:\temp\"), (Get-ChildItem "I:\temp\" -Directory -recurse) | % {
Get-ChildItem -File $_.FullName | Select-String -List -Pattern '^\d{3}-?\d{2}-?\d{4}$' |
% Path
}
if($locations -ne $null){
$locations | out-file "I:\temp\SSN_FILES.txt"
#Get-ChildItem "I:\temp\" -exclude "fullpath.txt","SSN_FILES.txt" | remove-item
}else{
Get-ChildItem "I:\temp\" -exclude "fullpath.txt","SSN_FILES.txt" | remove-item
}
}
}
}
So this basically says:
check for a file matching doc/docx/xlsx
convert them into a file that can be parsed through
parse through each file at every iteration and compare it to a regex
if the regex is not null, then output it to a file with the file path
otherwise, delete it and anything else that was created except for two files
restart the process at the next file
Now the problem I am encountering is that the files aren't being deleted. I can't get them to be removed when they are created, when I know they don't match the regex. Setting ($locations -eq $true) doesn't solve that issue because it never goes into the first conditional statement.
The folder should contain only the two files that were created and possibly the ones that match the regex.
