how do i get the filesize from a filename? and compare with IF statement

[nnnmmm]

Code: Select all

SET Y22=%~dp0Data\minigun_fire.wav
SET Y32=%~dp0Data\minigun_fire.wav

how do i get the filesizes of %Y22% and %Y32%?

IF EXIST "%Y22%"    IF filesize of %Y22%==100   ECHO  Sound MOD 1 installed
IF EXIST "%Y32%"    IF filesize of %Y32%==200   ECHO  Sound MOD 2 installed

IF NOT filesize of %Y22%==100   IF NOT filesize of %Y32%==200  (
ECHO  Sound MOD 1 is NOT installed
ECHO  Sound MOD 2 is NOT installed
GOTO :eof
)

IF filesize of %Y22%==100 (
ECHO  Sound MOD 1 is installed
ECHO  Sound MOD 2 is NOT installed
GOTO :eof
)

Surprised your searching did not find any of these links.
It is right on the main DosTips.com site library.

As well as discussed in several threads. Here is one of them.

No clue why you would assign the size of the same file to two different variables.

Code: Select all

>Surprised your searching did not find any...
i can get these if /? for /?
but i get no answers from the websearch of "batch command / > ^ /*... etc"
i used to get a headache looking for operator's meanings, it became a habit not to look for them much, then it kind of extended to other searchable areas.

>No clue why you would assign the size of the same file to two different..
my brain would recognize better a year later why i did this way 
i see patterns Y21 Y22 Y31 Y32 but if i introduce a new common variable...i may not recognize it fast  years later why

FOR %%J in ("%Y22%") DO SET YmiFS=%%~zJ
IF /I %YmiFS%==8842 (
IF /I %YmiFS%==35180 (

before my posting, i tried this way
%~z%YY2%
%YY2%~z0
%YY2%~z1
%YY2%~z2... thinking one them might hit the number
see i mimic, i have some knowledge of them but not all

SET Y21=%~dp0Data\!mod - minigun_fire.wav 1.exe
SET Y22=%~dp0Data\minigun_fire.wav
SET Y31=%~dp0Data\!mod - minigun_fire.wav 2.exe
SET Y32=%~dp0Data\minigun_fire.wav
FOR %%J in ("%Y22%") DO SET YmiFS=%%~zJ

   IF /I %VAR%==7 (
      PUSHD "%~dp0data"
      "%Y21%" -OVERWRITE -TIMES=MODIFY
      POPD
   )
   IF /I %VAR%==8 (
      IF /I EXIST "%Y22%" del /q "%Y22%"
   )

thanks for a help
