os.rename [WinError 32] The process cannot access the file because it is being used by another process

I am trying to move the files from the source folder to destination folder, however I am getting the error

_{PermissionError Traceback (most recent call last) Cell In[23], line 9 7 print("Moving {} to {}".format(os.path.join(sourcepath, f), os.path.join(destination, subpath , f))) 8 #os.makedirs(os.path.join(destination, subpath), exist_ok=True) ----> 9 os.rename(os.path.join(sourcepath, f), os.path.join(destination, subpath , f))}

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process

Apparently the file is being used by os.rename but I am struggling to close the loop. The code is:

sourcepath='C:/source'
destination='C:/destination'

(_,_,fnames) = next(os.walk(sourcepath))
for f in fnames:
    subpath = '/'.join(f.split('erFile_')[:+1])
    print("Moving {} to {}".format(os.path.join(sourcepath, f), os.path.join(destination, subpath, f)))
    os.rename(os.path.join(sourcepath, f), os.path.join(destination, subpath , f))

Any help is appreciated.

In this case, you can use the shutil.move function, which is more robust for file operations and will handle open files for you. Here's an example:

import os
import shutil

sourcepath = 'C:/source'
destination = 'C:/destination'

(_, _, fnames) = next(os.walk(sourcepath))

for f in fnames:
    subpath = '/'.join(f.split('erFile_')[:+1])
    source_file = os.path.join(sourcepath, f)
    destination_file = os.path.join(destination, subpath, f)
    print("Moving {} to {}".format(source_file, destination_file))
    
    try:
        shutil.move(source_file, destination_file)
    except Exception as e:
        print(f"Error moving {source_file} to {destination_file}: {e}")
