Need to find some specific files in removable drive

[prakashr85]

Friends I need to find/search for the existence of some files and store the result with filename and existence/non-existence in a txt file.

for example

I need to find new.txt, three.jpg, ty.doc in drive D: and store the result in txt file as filename found/not found.

Thanks in advance.

DIR /S should help to find the files. Try:

Code: Select all

@echo off &setlocal
set "drive=D:\"
set "file1=new.txt"
set "file2=three.jpg"
set "file3=ty.doc"

>"found.txt" (
  for /f "delims=" %%i in ('dir /a-d /b /s "%drive%%file1%" "%drive%%file2%" "%drive%%file3%" 2^>nul') do (
    if "%%~nxi"=="%file1%" (
      echo "%%i"
      set "found1=true"
    )
    if "%%~nxi"=="%file2%" (
      echo "%%i"
      set "found2=true"
    )
    if "%%~nxi"=="%file3%" (
      echo "%%i"
      set "found3=true"
    )
  )
)

>"not found.txt" (
  if not defined found1 echo "%file1%"
  if not defined found2 echo "%file2%"
  if not defined found3 echo "%file3%"
)

I'd just change this:

if "%%~nxi"==

to this in three places, to make the match case insensitive.

if /i "%%~nxi"==

Thanks a billion,

But I need to find hundreds of files when I tried it took more than 5 minutes, can we still have any optimized code with getting filename from an ext. text file.

Is two batch files an option?

Thanks, I need files that are not found in the list.txt also

[foxidrive]

Where are they found? Do you want to pass filenames on the command line to the batch file?

[prakashr85]

Thanks a lot for your timely help. Like the previous post code I need output files such as not-found.txt and found.txt in your code only found.txt is the only output.
For example I need to find 3 three files named one.txt, two.png, three.jpg in drive D: and drive d: has only one file say one.txt, your code returns only the files which are found in D: but I need both in separate files as found.txt(contains one.txt) and not found.txt (contains two.png, three.jpg) hope its clear now.

Does this work for you? The other first batch file is still needed to produce the filelist.txt

Code: Select all

:: create file list
@echo off
dir d:\ /a-d /b /s >filelist.txt

Code: Select all

@echo off
:: search for filenames
(
echo \new.txt
echo \three.jpg
echo \ty.doc
) > "list.txt 

findstr /i /g:"list.txt" "filelist.txt" >"foundfiles.txt"
findstr /v /i /g:"filelist.txt" "list.txt" >"notfoundfiles.txt"

Edit: reversed the last line

[prakashr85]

notfound.txt lists all files from the drive D: except the one found, To made it simple

Code: Select all

Drive D: contains the following files
------------------------------------
ty.doc
two.jpg

INPUT
-------
List.txt (files that i need to search/find in D:)
---------------------------------------------
ty.doc
two.jpg
three.png

OUTPUT:
-----------
Found.txt contents
----------------------
ty.doc
two.jpg

Notfound.txt Contents
---------------------
three.jpg

Try the batch above again - I edited the post.

[prakashr85]

Tried notfound.txt displays all the contents of list.txt file

[foxidrive]

Ok, sorry for the false leads. This has been lightly tested. Try the batch file at the bottom which simulates a disk with three files, one of which is not in the list to be found.

Code: Select all

@echo off
:: create file list
@echo off
dir d:\ /a-d /b /s >filelist.txt

del "filelist2.txt"  2>nul
for /f "delims=" %%a in (
'type "filelist.txt"'
) do echo>>"filelist2.txt" \%%~nxa

Code: Select all

@echo off
:: search for filenames
(
echo \new.txt
echo \three.jpg
echo \ty.doc
) > "list.txt

findstr /i /g:"list.txt" "filelist.txt" >"foundfiles.txt"
findstr /v /i /g:"filelist2.txt" "list.txt" >"notfoundfiles.txt"

Code: Select all

@echo off
:: create file list
(
echo d:\folder\new.txt
echo d:\folder 3\threeB.jpg
echo d:\a place here\ty.doc
) > "filelist.txt

del "filelist2.txt"  2>nul
for /f "delims=" %%a in (
'type "filelist.txt"'
) do echo>>"filelist2.txt" \%%~nxa



@echo off
:: search for filenames
(
echo \new.txt
echo \three.jpg
echo \ty.doc
) > "list.txt

findstr /i /g:"list.txt" "filelist.txt" >"foundfiles.txt"
findstr /v /i /g:"filelist2.txt" "list.txt" >"notfoundfiles.txt"

[prakashr85]

Still I get all files in notfoundfiles.txt

[foxidrive]

Try the last batch file above which demonstrates the technique:

I only get this filename in the notfound file.

\three.jpg
