Hello,

first of all thank you for publishing your great work! It saved a lot of time for me.
In sake of improving open source software, I would like to point out three things I noticed when using your script.

1. Wrong Hashes

In line 65, you are using os.path.join() to generate the new file string. In my case, this leads to the following string, since I'm using Windows and Backslash is Standard:

file:C:/Users/weberlu/Desktop/neuer_pfad/gross\15-0000598.png

This does not lead to an error, however, the MD5 hash is completely wrong because of that.

Changing line 65 from
source_asset_path = 'file:'+os.path.join(directory_name, asset['name'])
to
source_asset_path = 'file:'+ directory_name + '/' + asset['name']
fixes this issue.

2. Extra Line between each Line

After running your script, I get a blanc line between each JSON entry:

{

    "name": "Test",

    "securityToken": "Test Token",

I fixed this by adding
line = line.replace("\\n","")
below
line = line.replace(old_source_directory, node_ready_new_source_directory)

3. Remove click functionality

The click functionality is not stable for Windows users. Just pass the new_source_directory and target_directory (with Slashes, not Backslashes!) as string parameter into the main() function!

Thats all from me and maybe helps another windows user.
Keep up the good work!
