Hi all,
Nice to join the group. I need your help to create a PowerShell script.

I want to rename files in subdirectories, with sum delta value to the current one.

The filenames contain 20 digits as below:

00000000000000000010.txt

00000000000000000100.txt

00000000000000003000.txt

00000000000000003500.txt

I need to sum delta value 300 to all files:

00000000000000000310.txt

00000000000000000400.txt

00000000000000003300.txt

00000000000000003800.txt

Thanks in advance!

Hi

So far I have to create to csv files and do it on that way, but there are millons of records and need faster way to do it

$csv = Import-CSV “\sharepath\file.csv”

foreach ($row in $csv) {

$toRename = $row.FullPath

$newName = $row.NewName

Rename-Item -Path $toRename -NewName $newName
