Exclude specific file extension - windows

Question

Alright, I'm new to scripting and I'm trying to edit a batch script file that sends an email when a file with an extension of .ecl is in a folder longer than 5 min or so. But there are other files with a .ecl.part extension that get flagged and it sends an email instead of the .ecl files. I'm curious if there is something I can add so that it will send an email when there are .ecl files in the folder for more than 5 min and ignore the .ecl.part files. I read one for someone with Linux who used [!(.extension to exclude)].extension not to exclude, I'm just wondering if this will work for my windows batch script. If it will work do I add it just like that or do I add it like this .extension not to exclude[!(.extension to exclude)]
Here is the part of the script in question:
for /f "tokens=1-5 delims=:, " %%a in ('forfiles /p z: /d +0 /s /m *.ecl /c "cmd /c if #isdir==FALSE echo #file,#ftime"') do (
set fnam=%%a
set fhr=%%b
set fmin=%%c
set fsec=%%d
set fampm=%%e
if "!fampm!" == "PM" if "!fhr!" neq "12" (set /a "fhr=!fhr!+12")
There is more of the script, I didn't set this up, and the person who did isn't being very helpful which is why I came here.

Answer 1

#ECHO OFF
SETLOCAL
SET savearea=c:\destdir
SET emldir=c:\sourcedir
ECHO.>"%savearea%\emlfiles.new"
DIR /b /a-d /on "%emldir%\*.eml" >>"%savearea%\emlfiles.new"
IF NOT EXIST "%savearea%\emlfiles.old" GOTO noold
FOR /f "usebackqdelims=" %%i IN ("%savearea%\emlfiles.new") DO (
FINDSTR /b /e "%%i" "%savearea%\emlfiles.old" >NUL
IF NOT ERRORLEVEL 1 (ECHO %%i is MORE than 5 minutes old)
)
:noold
MOVE /y "%savearea%\emlfiles.new" "%savearea%\emlfiles.old" >nul
GOTO :eof
This script saves in %savearea% a sorted basic filelist of the *.eml files in %emldir% then compares the new list to the previous version. If the same filename appears in both, it will generate the message %%i is MORE than 5 minutes old
So - all you need to do is point emldir to wherever your .eml files reside, savearea to some safe directory, replace the message ECHOing with an email-sending command of your liking and schedule it to run each 5 minutes using task scheduler.

Although in my testing I find this not to be the case, it sounds like forfilesis evaluating wildcards against 8.3 short filenames on your computer. You know how if you're in a directory containing both .doc and .docx files and you do a dir *.doc, the .docx files will be listed as well? Same sort of thing.
So *.ecl is matching your .ecl.part files because in 8.3 notation they've got a .ecl extension. You could either make sure %fnam:~-4%==.ecl, enclosing most of the guts of your for loop within an if statement; or you can use find or findstr to filter the output of forfiles as captured by the for loop. Something like this:
for /f "tokens=1-5 delims=:, " %%a in (
'forfiles /p z: /d +0 /s /m *.ecl /c "cmd /c if #isdir==FALSE echo #file,#ftime" ^| find /v /i ".part"'
) do (
set fnam=%%a
set fhr=%%b
set fmin=%%c
set fsec=%%d
set fampm=%%e
if "!fampm!" == "PM" if "!fhr!" neq "12" (set /a "fhr=!fhr!+12")
rem etc.
Since find /v prints lines not matching its search, that should effectively filter out the .ecl.part files. find /v works like grep -v in Linux.
You know, since my test cases don't seem to match the symptom you're describing, I am very curious to know whether simply replacing if #isdir==FALSE with if #ext==\"ecl\" would also prevent the .ecl.part files from being included. But if you don't feel like experimenting to satisfy my curiosity, I totally understand.
