Answer 1

Thank you, Developers, for responding to my query. I have resolved the issue. The problem was, Windows keeps building Thumbnails and stores them as Thumbs.db on the system.This prevents the system from copying, moving, deleting or renaming a folder. I prevented further caching of thumbnails and deleted the Thumbs.db from the project folder.
This is the procedure if anyone else comes across this problem:
1. Disabling Thumbs.db:

2. Next, to remove Thumbs.db:

This will do the job. :)

Answer 2

Seems like your folder name has a white space try to rename the folder name and try to run it again.
Existing Path:
C:\Users\Vivek Sharma\apps\testAp p\www\assets\imgs\Thumbs.db
Change Path like this:
C:\Users\VivekSharma\apps\testApp\www\assets\imgs\Thumbs.db
You could see whitespace in between Vivek Sharma change it to VivekSharma For more info check this out:
