Using Everything to copy a selected found files into another Drive USB

[happydz]

As the titles says, I search for all pictures stored in my PC, then I sorted them by extension, then I selected only .JPG pictures which I need to copy to USB, however, the result of Everything shows 13 582 pictures of jpg, but when the copy process started, I noticed that the total of pictures are only 13 382 pictures of jpg.
How to fix this error?

[void]

Everything uses the system to copy files.

Maybe there's duplicated images or filenames?
Was a conflict dialog shown during the copying?

Please try the Advanced Copy from Edit -> Advanced -> Advanced Copy to folder:

• Check Regular expressions.
• Set the old format to: (.*)\\([^\\]*)\\([^\\]*)
• Set the new format to: E:\\backup\\\2\\\3
  (where E: is your USB drive)
• Review the generated filenames and click OK.

(This will copy the selected files to the E: drive, preserving the parent folder)
