I have three or more directories with subdirectories in which I have to check and sort thousands of files named "00001_*.jpg" to "99999_*.jpg".

But for the sake of keeping it simple, we will test a sample of 20 images.

For example I have three parent directories A, B and C. Inside of directory B are four images 00017_0.jpg, 00018_0.jpg, 00019_0.jpg and 00020_0.jpg. I would like to run a script which detects those filenames e.g. in directory A and move them into a subdirectory named Check, (ACheck).

I have tried to store filenames into an array, but I am already stuck. I tried to store them into list_1, but when I echo the result I get nothing "".

I edit the path to the images in directory B in FolderPath using parameters: default, default, 20

Resulting in:

Start value (default: 1):
Increment by: (default: 1):
Last value (default: 99999): 20
Not exist: 00001_0.jpg
Not exist: 00002_0.jpg

Not exist: 00006_0.jpg

Not exist: 00009_0.jpg
Not exist: 00010_0.jpg
Not exist: 00011_0.jpg
Not exist: 00012_0.jpg
Not exist: 00013_0.jpg
Not exist: 00014_0.jpg
Not exist: 00015_0.jpg
Not exist: 00016_0.jpg
Found file: 00017_0.jpg
Found file: 00018_0.jpg
Found file: 00019_0.jpg
Found file: 00020_0.jpg
"The length of the array is" 0
Press any key to continue . . .

Below is my adaption of this script.

It found the files in directory B, but my additions regarding list_1 array have not worked out, so I am unable to move them the Check subdirectory; (this part is not yet scripted).

@echo off
setlocal EnableExtensions DisableDelayedExpansion
set "list_1="
set "ValueStart=1"
set "ValueIncrement=1"
set "ValueLast=99999"
set /P "ValueStart=Start value (default: %ValueStart%): " 
set /P "ValueIncrement=Increment by: (default: %ValueIncrement%): "
set /P "ValueLast=Last value (default: %ValueLast%): "

set "FolderPath=%USERPROFILE%foldersubfolder"
setlocal EnableDelayedExpansion
for /L %%G in (%ValueStart%,%ValueIncrement%,%ValueLast%) do (
    if %%G LSS 100000 (
        set "FileName=0000%%G"
        set "FileName=!FileName:~-5!_0.jpg"
    ) else set "FileName=%%G_0.jpg"
    if exist "!FolderPath!!FileName!" (
        set "list_1[%%G]=FileName"
        echo Found file: !FileName!) else echo Not exist: !FileName!
)

set "x=0"
:SymLoop 

if defined list_1[%x%] ( 
   call echo %%list_1[%x%]%% 
   set /a "x+=1"
   GOTO :SymLoop 
)
echo "The length of the array is" %x%
pause
endlocal
