Python WinError 32 The process cannot access the file because it is being used by another process

I made a script that converts pdf files into jpgs and then puts those jpgs in a specific folder. The script works fine so far but, I keep getting an error in the VScode terminal that says :

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:/Users/xxx/Desktop/pdf2jpg/src_files/Files/'

I tried closing the file before running but, it still does it

from pdf2image import convert_from_path
import glob, os
import os, subprocess
import shutil

pdfPath = "C:/Users/xxx/Desktop/pdf2jpg/src_files/Files/"
os.chdir(pdfPath)

for pdf_file in glob.glob(os.path.join(pdfPath, "*.pdf")): #converts PDF files from pdfPath then 
#converts
pages = convert_from_path(pdf_file, 500)   
for page in pages:       
    page.save(pdf_file[:-4] +".jpg", 'JPEG')

for i in os.listdir(pdfPath): #removes orginal PDF files
    if i.endswith('.pdf'):
        os.remove(i)

jpgPath = "C:/Users/xxx/Desktop/pdf2jpg/ConvertedFilesJPG/"

fileNum = 0
foldNum = 0                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
for base, dirs, files in os.walk(jpgPath): #checks number of folders in the destination path   
for directories in dirs:
    foldNum += 1                       
for Files in files:
    fileNum += 1
print(foldNum) #for debugging

if os.path.exists(jpgPath): 
    strNum = foldNum + 1
    fStrNum = str(strNum)
    strJpgPath = jpgPath + "Files" + fStrNum + "/"  #adds number of files in path, so new folders can 
    #be organized by name 
    shutil.move(pdfPath, strJpgPath)

Answer

Your script starts by doing

os.chdir(pdfPath)

so the process running your script is the one holding the pdfPath directory, and preventing it from being removed by shutil.move. Just do a chdir somewhere else before moving it, for example:

chdir("C:/Users/xxx/Desktop/pdf2jpg/")
if os.path.exists(jpgPath):
    ...
