Batch rename files and organize them Bat Script - windows

Question

Friends, I need to rename pdf files to a certain standard. For that I made the following script:
c:
cd \importation
if not exist %1 goto end
md %~n1
move %1 %~n1\P%~n1_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %2 goto end
md %~n2
move %2 %~n2\P%~n2_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %3 goto end
md %~n3
move %3 %~n3\P%~n3_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %4 goto end
md %~n4
move %4 %~n4\P%~n4_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %5 goto end
md %~n5
move %5 %~n5\P%~n5_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %6 goto end
md %~n6
move %6 %~n6\P%~n6_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %7 goto end
md %~n7
move %7 %~n7\P%~n7_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %8 goto end
md %~n8
move %8 %~n8\P%~n8_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
if not exist %9 goto end
md %~n9
move %9 %~n9\P%~n9_V1_A0V0_T07-54-369-664_S00001_Volume.pdf
:end
It turns out that the script only modifies up to 9 files at a time. Does anyone know how I can make this change to all files in the folder? Sometimes there are 100,200 or even more pdfs

Answer 1

Use Get-ChildItem to discover the files, then inspect their BaseName property to get the file name without the extension:
$rootFolder = 'C:\importation'
Get-ChildItem $rootFolder -File -Filter *.pdf |ForEach-Object {
# create new folder
$newFolder = mkdir -Path $rootFolder -Name $_.BaseName
# construct target path
$targetPath = Join-Path $newFolder.FullName "P$($_.BaseName)_V1_A0V0_T07-54-369-664_S00001_Volume.pdf"
# move file
$_ |Move-Item -Destination $targetPath
}

Answer 2

This should work
# Define variables
$Folder = "C:\myfolder"
$OldFileName = "OldFileName1.pdf"
$NewFileName = "NewFileName1.pdf"
# Get all files in the folder non-recursively
$Files = Get-ChildItem $Folder
# For each file
foreach ($File in $Files){
# If file matches the OldFileName
If ($File.Name -eq $OldFileName){
# Rename the file to the new name
Rename-Item -Path $File.FullName -NewName $NewFileName
}
}
