Windowserror: [error 2] The System Cannot Find The File Specified, Cannot Resolve In Python

I have made a Python program which will clean up the unnecessary names present in my downloaded torrent files+folders, so that I can upload it to my unlimited Google Drive Storage

Solution 1:

Probably it's the problem with subdirectories due to the way os.walk works, namely path on next iteration after the first with subdirectories. os.walk gathers subdirectories' names to visit on further iterations on it's first iteration in current directory...

E.g., on first call to os.walk you get:

('.', ['dir1', 'dir2'], ['file1', 'file2'])

now you rename the files (this works ok), and you rename: 'dir1' to 'dirA' and 'dir2' to 'dirB'.

On next iteration of os.walk, you get:

('dir1', ['subdir1-2', 'subdir1-2'], ['file1-1', 'file1-2'])

And what happens here is there's no 'dir1' anymore, as it is already renamed on the file system, but os.walk still remembers it's old name in the list inside and gives it to you. Now, when you try to rename 'file1-1' you ask for 'dir1/file1-1', but on the file system it's actually is 'dirA/file1-1' and you get the error.

To solve this issue, you need to change the values in the list that is used by os.walk on further iterations, e.g. in your code:

for (path, dir, files) in os.walk(p):
    for name in terms:
        for i in files:
            if name in i:
                print i
                fn, _, sn = i.rpartition(name)
                os.rename(os.path.join(path, i), os.path.join(path, fn+sn))
        foriindir:
            ifnameini:
                printifn, _, sn = i.rpartition(name)
                os.rename(os.path.join(path, i), os.path.join(path, fn+sn))
                #hereremovetheoldnameandputanewnameinthelist
                #thiswillbreaktheorderofsubdirs, butitdoesn't
                #breakthegeneralalgorithm, thoughifyouneedtokeep
                #theorderuse '.index()' and '.insert()'.
                dirs.remove(i)
                dirs.append(fn+sn)

This should do the trick and in described above scenario, will lead to...

On first call to os.walk:

('.', ['dir1', 'dir2'], ['file1', 'file2'])

now rename: 'dir1' to 'dirA' and 'dir2' to 'dirB' and change the list as shown above... Now, on next iteration of os.walk it should be:

('dirA', ['subdir1-2', 'subdir1-2'], ['file1-1', 'file1-2'])
