Finding an exe from any hard drive and setting it as a variable

Solution 1:

To improve your code:

Use dir /s /b to get just the bare file-name.

To get the result of the dir command into the variable, use an inner loop like that:

FOR /F "USEBACKQ" %%F IN (`dir /s /b ffprobe.exe`) DO (
SET var=%%F
)
ECHO %var%

Solution 2:

Any of the resulting files could be set as the variable (like the last one), but the latest (by date or version) would be optimal.

To scan all drivers:

@echo off

setlocal enabledelayedexpansion && set "_f=" && set "_ff=" && set /a "_cnt=0" 
for /f usebackq^tokens^=* %%f in (`%__AppDir__%mountvol.exe^|find.exe /i ":\"
    `)do 2>nul pushd %%~f && (set/a "_cnt+=1" && call %:^) _ff_!_cnt! & popd)
    
for /f useback^tokens^=1*delims^=^=^  %%i in (`^<nul ^<con: set _ff_^|%__AppDir__%sort.exe /r
    `)do <con: <nul call set "_ffprobe=%%~dpnxj" & call set "_ffprob_Path=%%~dpj" & goto %:^|
 
%:^)
for /f usebackq^tokens^=2^,4* %%i in =;(`2^>nul %__AppDir__%where.exe /r \ ffprobe.exe /t ^|^
    %__AppDir__%sort.exe /r^|^|exit/b`)do set "_f=%%~k" && for /f useback^delims^=. %%G in (`
        ^<con %__AppDir__%wbem\wmic.exe DataFile where name^="!_f:\=\\!" get LastModified ^|^
            %__AppDir__%findstr.exe /rb [0-9]`)do <con: <nul call set "%~1=%%~k" && exit /b 0

%:^|
<con: rem.// your code continues at this point using: & echo+!_ffprobe! & echo+!_ffprob_Path!

To limit to only in Local Disk (DriveType=3 == HD's):

@echo off

=====setlocal enabledelayedexpansion && set/a "_cnt=0" & call set _ff=<nul & call set _f=<nul
for /f usebackq^delims^= %%i In (`%__AppDir__%wbem\wmic.exe LogicalDisk where DriveType^='3'^
    get caption^|find ":"`)do pushd %%~i && (set/a "_cnt+=1" && call %:^) _ff_!_cnt! & popd )

for /f useback^tokens^=1*delims^=^=^  %%i in (`^<nul ^<con: set _ff_^|%__AppDir__%sort.exe /r
    `)do <con: <nul call set "_ffprobe=%%~dpnxj" & call set "_ffprob_Path=%%~dpj" & goto %:^|
 
%:^)
for /f usebackq^tokens^=2^,4* %%i in =;(`2^>nul %__AppDir__%where.exe /r \ ffprobe.exe /t ^|^
    %__AppDir__%sort.exe /r^|^|exit/b`)do set "_f=%%~k" && for /f useback^delims^=. %%G in (`
        ^<con %__AppDir__%wbem\wmic.exe DataFile where name^="!_f:\=\\!" get LastModified ^|^
            %__AppDir__%findstr.exe /rb [0-9]`)do <con: <nul call set "%~1=%%~k" && exit /b 0

%:^|
<con: rem.// your code continues at this point using: & echo+!_ffprobe! & echo+!_ffprob_Path!

1. Get all available drivers

2. Scan each validated drive

3. Use size-ordered output

4. Get the LastModified date

5. Save Last Modified date and Path one by one

6. Use date inversion and get latest/highest number

Obs.: Scan each hd, as well as each pen drive, memory card, cd (if any media is present on the drive), keep in mind that it may take some time...
