Pass path with spaces as parameter to bat file

Question

I have a simple bat script that copies files from an known directory to a directory given by the user  How can I pass the path  it might contain spaces  to my script and use it with the xcopy command     In my code i have the following   READ PWA PATH     if   1                   rem Set default path         set PWA PATH  C  Program Files PWA          rem         echo You have not specified your PWA url          echo Default will be assumed  C  Program Files PWA           choice  C YN  M  Do you wish to continue  Y  or cancel the script  N                IF ERRORLEVEL   2 GOTO CANCEL             IF ERRORLEVEL   1 GOTO READ WSS SERVER EXTENSIONS PATH         GOTO END       else           set PWA PATH  1         If I simply call the script I get the following error   C  Projects Setup gt install cmd  C  program files  x86    ----------------- SETUP SCRIPT -----------------  files was unexpected at this time  C  Projects Setup gt

If your path contains space then try using   s1  This will remove the space and appends  1 to your path and more importantly it refers to the absolute path of your file  Try using it

If you have a path with spaces you must surround it with quotation marks       Not sure if that s exactly what you re asking though

Interesting one  I love collecting quotes about quotes handling in cmd command   Your particular scripts gets fixed by using  1 instead of   1       By adding an  echo on    or getting rid of an echo off    you could have easily found  that out

Use    1     1 alone removes surrounding quotes  However since you can t know whether the input parameter  1 has quotes or not  you should ensure by    1  that they are added for sure  This is especially helpful when concatenating variables  e g  convert exe    1 input     1 output

I think the OP s problem was that he wants to do BOTH of the following    Pass a parameter which may contain spaces Test whether the parameter is missing   As several posters have mentioned  to pass a parameter containing spaces  you must surround the actual parameter value with double quotes   To test whether a parameter is missing  the method I always learned was   if   1          However  if the actual parameter is quoted  as it must be if the value contains spaces   this becomes  if   actual parameter value           which causes the  unexpected  error   If you instead use  if  1         then the error no longer occurs for quoted values   But in that case  the test no longer works when the value is missing -- it becomes  if          To fix this  use any other characters  except ones with special meaning to DOS  instead of quotes in the test   if   1        if   1        if abc 1xyz    abcxyz
