Unable to copy in bluestacks

I have ran into this problem when copying movies from Showbox and have not found a solution until now. I have tried increasing the RAM size with no luck. The only thing that did work was uploading to Dropbox.

But I recently tried trick which seems to work consistently:

• Open ES explorer (Install it if you don't have it) and click on the homepage within it.
• Then click Clean Now over on the right hand side - this brings up the ES cleaner.
• Clean all, then go back to the folder with your file and try copying.

This seems to work for me. I have increased my RAM size before this - although it did not work - but it could be the combination of both. I will try resetting my Bluestacks RAM back to stock and try it.

How are you copying data into Blue stacks? Are you connected through LAN as you can also try to connect to your PC in bluestacks through searching for your PC under LAN (it searches for IP address of local system connected to bluestacks). Also you can put your files inside a folder and share it for all of the users. Bluestacks will detect it and you can copy files into Bluestacks.

Also you can try the method on this site.
