I have a directory that has image files without extension. Let us say it to be D:initial. Now I want to copy those files over to D:final directory and change the extension to .jpg for each file.

My solution using ROBOCOPY:

@echo off



SET srcDir=D:initial

SET destDir=D:final



echo Copying files from %srcDir%

ROBOCOPY %srcDir% %destDir% /s /min:102400

echo Copying done



cd %destDir%



echo Renaming to JPG

ren *. *.jpg

However, there are certain conditions:

1. Copy only those files that are greater than 100 KB in size.


2. Do not delete files in the source directory.


3. The source directory will at certain periods, get newer files; copy them to the destination directory (manually, no automation needed here)

My solution meets the first two conditions, but when I run again after new files arrive, the older ones get copied over too thus giving error at renaming.

windows cmd.exe file-transfer robocopy

  Rename files in the source directory and just run robocopy like usual. Robocopy should optimize and skip existing files.

Check file size and if destination file exists with an iterating for on the sourcefiles.

And use xcopy instead of invoking robocopy every time what would be overkill here.

Copying to the new name with extension in one go eliminates the need to rename.

@echo off



SET "srcDir=D:initial"

SET "destDir=D:final"



echo Copying files from %srcDir%

For %%A in ("%srcDir%*.") do (

    if %%~zA gtr 102400 if not exist "%destDir%%%~nA.jpg" copy "%%~fA" "%destDir%%%~nA.jpg" >NUL

)

echo Copying done

xcopy <srcDir> <destDir>.<append>

example
xcopy c:Photos_with no_extensions* c:Jpegs*.jpg

or for you xcopy D:initial* D:final*.jpg

It will copy all the files in the first director to the second and add .jpg to the end. One drawback is it just adds on the new extension i.e. file.pdf would become file.pdf.jpg
