Feature description

When copying and pasting files between folders in my gallery, I often encounter the situation of wanting to paste files with the same name in the destination folder. Since filenames can be simple alphanumeric strings that are very long and nobody remembers, I would like the "possible duplicate" warning dialog to include:

1. A preview thumbnail of the source file (the file being pasted)
   

2. A preview thumbnail of the destination file (the existing file)
   

3. A rename option for the source file when files are different but share the same name
   

This would allow users to:

• Visually compare if files are actually duplicates
  

• Cancel the operation if they are the same file
  

• Rename the incoming file if they are different files with the same name
  

Why do you want this feature?

Currently, when pasting files with duplicate names, I have no visual way to determine if the files are actually the same or just happen to share the same filename. This creates several problems:

• Risk of accidentally overwriting different files that happen to have the same name
• Time wasted trying to remember or check what each file contains
• No option to keep both files when they are legitimately different
• Potential data loss from overwriting unique files

This feature would prevent accidental data loss and provide better file management control during copy/paste operations.
