The below script works fine.  Just a little slow.  It is because it is searching so many drives.   but is there a way to make the script 'faster"? Even a second or two would be nice

One thing I should mention is, the "bquest" folder would be located somewhere in the folder %programfiles%.  maybe we can edit this to go directly to that directory first...

@echo off
(for %%i in (C D E F G) do (dir %%i:\*bquest /s /b /ad))>dir_search.txt
for /f "tokens=* delims=" %%x in (dir_search.txt) do (
    if not exist "%%x\keycode" (  
    copy /v /y etkey "%%x\keycode" >NUL 2>&1
    attrib +r "%%x\keycode" >NUL 2>&1
  )
)

Hi, one way to make it faster would be to change
(dir %%i:\*bquest /s /b /ad)
to
(dir %%i:\program files\*bquest /s /b /ad)

Note: You need to hardcode Program Files instead of %programfiles% because the %programfiles% variable contains a drive letter.

Another way to make it faster would be to create a separate batch file for each drive, as in

(dir "C:\Program Files\*bquest" /s /b /ad))>dir_search.txt
for /f "tokens=* delims=" %%x in (dir_search.txt) do (
    if not exist "%%x\keycode" (  
    copy /v /y etkey "%%x\keycode" >NUL 2>&1
    attrib +r "%%x\keycode" >NUL 2>&1
  )
)

Open in new window


and
(dir "D:\Program Files\*bquest" /s /b /ad))>dir_search.txt
for /f "tokens=* delims=" %%x in (dir_search.txt) do (
    if not exist "%%x\keycode" (  
    copy /v /y etkey "%%x\keycode" >NUL 2>&1
    attrib +r "%%x\keycode" >NUL 2>&1
  )
)

Open in new window


etc, and then kick them all off at the same time.  This way you search each drive concurrently, instead of sequentially.

Regards,

Rob.
