Adding file name information to CSV file columns
Assuming you commented out the second file generation of these two:

GET-CONTENT (GET-CHILDITEM "E:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS3\*.out") | out-file -encoding "UTF8" "C:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS3\CBM-FS3.txt"

GET-CONTENT (GET-CHILDITEM "C:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS56\*.out") | out-file -encoding "UTF8" "C:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS04\CBM-FS04.txt"


You can combine the above lines using the -LiteralPath parameter to Get-ChildItem, like so:

GET-CONTENT (GET-CHILDITEM -LiteralPath 'E:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS3\*.out', 'C:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS56\*.out') | out-file -encoding "UTF8" "C:\Users\jsweeton\Documents\SITES\CBM\Storage Analysis\CBM-FS3\CBM-FS3.txt"


If that's not what you're looking for or you need more input, just let me know and I'll update my answer accordingly.
