Windows 7: App to choose random files from a folder and copy/move it to another?

App to choose random files from a folder and copy/move it to another?

Hey all!

I think that the title says for itself...

I manage a group in Facebook with female illustrations (pinups, super-heroins, manga and art in general) and that I use to market a small online business of mine. I use to post around 20 pictures a day there and till the date I have chosen manually the picture set. At first it doesn't seem to be a lot of work but it becomes crazy as the collection gets bigger (mine is around 10 thousand and growing).

Because my lazy nature lately I have ended picking 20 of my favorite pictures among the first ones of the collection but I would like that the pictures were more random and totally independent of my personal taste.

I have found a small app called 'Pick me' that does almost what I need: it nicely selects 20 random files by the name and makes a list. However it is still crazy to run the list manually item by item and locate the files within a huge collection. Ideally the app should copy (or move) the selected files to a certain folder...

I was wondering if such app does exist?

Is that generated list just a simple txt file with all the filenames inside?
If so, it's fairly easy to build a bat file to do the copy from the list:

Hi Yankleber,

As Alejandro has suggested, a script is what you need and I have gone ahead and created one for you, Yankleber.

@echo off
setlocal EnableDelayedExpansion

set "source_path="    &REM Current directory is used if not defined
set "destination_path="    &REM Output is displayed on console if not defined
set "select=20"

goto :main

:get_random_integer Min Max [VarName]
	set /a max=%~2, min=%~1
	set /a value=(MAX * %RANDOM%)/ 32768 + MIN
endlocal & if not "%~3"=="" ( set "%~3=%VALUE%" ) else ( set "value=%VALUE%" )
goto :eof

:get_random_lines TextFileName Amount
setlocal EnableDelayedExpansion
	if "%~2"=="" exit /b 1
	if "%~1"=="" exit /b 1
	for /f "delims=" %%I in ('type "%~1" ^| find /c /v ""') do set /a "n_lines=%%~I"
	if %~2 gtr %N_LINES% echo Selected number of files exceeds the number of avaliable files >&2&& exit /b 1
	set /a iter=0
	set "used_lines="
	set "pass=FALSE"
	call :get_random_integer 0 %N_LINES%
	if %VALUE% equ 0 (set "options="useback delims="") else (set "options="skip=%VALUE% useback delims="")
	for /f %OPTIONS% %%I in ("%~1") do (
		for %%J in (%USED_LINES%) do if "%%~J"=="%VALUE%" set "pass=TRUE"
		if /i !PASS!==FALSE (echo %%I)
		goto :break
	if /i %PASS%==FALSE set /a iter+=1
	set "pass=FALSE"
	set "used_lines=%USED_LINES%,%VALUE%"
	if %ITER% lss %2 goto :get_random_line__while
goto :eof

pushd %SOURCE_PATH% 2>NUL || echo Source path does not exist&& exit /b 1
set "tempfile_files=%TEMP%\%~nx0_%RANDOM%.tmp"
for /f "delims=" %%I in ('dir /a:-d /b ^| findstr /vixc:"%~nx0"') do (>>"%TEMPFILE_FILES%" echo %%I)
	set "destination_path=!DESTINATION_PATH:"=!"
	if not exist "%DESTINATION_PATH%" echo Destination path does not exist&& exit /b 1
	set "tempfile_rand=%TEMP%\%~nx0_2_%RANDOM%.tmp"
	if exist "!TEMPFILE_RAND!" del "!TEMPFILE_RAND!"
	call :get_random_lines "%TEMPFILE_FILES%" %SELECT% >>"!TEMPFILE_RAND!" || (
		exit /b 1
	for /f "useback delims=" %%I in ("!TEMPFILE_RAND!") do (
		move "%%~I" "%DESTINATION_PATH%" >NUL
) else (
	call :get_random_lines "%TEMPFILE_FILES%" %SELECT%

Hey Pyprohly!

It was more than perfect for what I needed! The only really small change I made is that I replaced the move command with copy. Other than that I didn't have to do anything else but to create a folder to where the files will be copied and declare it within your PERFECT script!

Thank you very much! I was really giving up about to find an application and was thinking about to write one myself in C# (but not very excited about this indeed).

You saved me a LOT!

Thank you! Thank you! Thank you! Thank you!
