Conversione batch .rar in .7z - variabile di percorso?

Ho trovato qualcuno che aveva scritto uno script batch molto carino per convertire .zip in .7z e sto tentando di farlo convertire .rar in 7z. Sono in grado di far funzionare lo script ma non riesco a capire dove è impostata la variabile "PATH", come spiegato "Lo strumento da riga di comando 7-Zip (7za.exe) si trova in una posizione impostata nella variabile PATH." Attualmente l'unico modo in cui funziona è se mi assicuro di avere tutti i file exe / dll 7z nella directory dei file che devono essere convertiti. ma voglio usare lo script con un'opzione / s per le sottodirectory / ricorsive, e fallisce quando entra in una directory e i file exe / dll 7z non sono presenti.

Ecco la sceneggiatura -

ECHO.

REM Takes a Zip file and recompresses it as 7z archive.
REM Script process:
REM    1. Decompress the existing archive.
REM    2. Compress the extracted files in 7z format.
REM    3. (optional) Validate the new 7z file.
REM    4. (optional) Delete the source archive.
REM
REM Usage:
REM DeepArchive ZipFile
REM
REM Requirements:
REM    The 7-Zip command line tool (7za.exe) is in a location set in the PATH variable.
REM
REM Additional Notes:
REM This script processes a single zip archive.
REM To process all zip archives in a folder, use the ForFiles command from the command line:
REM    FORFILES /P "pathtozipfiles" /M *.zip /C "cmd /c DeepArchive @path"
REM
REM To run the archive compression/decompression as low priority background processes
REM add this in front of the 7ZA commands (DO NOT add this in front of the validation 7ZA command):
REM    START /BelowNormal /Wait 
REM Adding the above command will use a new window to perform these operations.

REM Should the deep archive file be validated? (1=yes, 0=no)
