   CMD alone doesn't have the capability to check whether a file/directory is   
   really movable/deletable or not.   
      
   My suggestion is to use a VBScript for checking that. Below VBScript will   
   check the given file/directory, and return an exit code which can be checked   
   using ERRORLEVEL or the %ERRORLEVEL% variable.   
      
     set fso = createobject("scripting.filesystemobject")   
     on error resume next   
     if fso.folderexists(wscript.arguments(0)) then   
       set d = fso.getfolder(wscript.arguments(0))   
       n = d.name   
       d.name = n & "z"   
       e = err.number   
       if e = 0 then d.name = n   
     else   
       set f = fso.opentextfile(wscript.arguments(0), 8, false, 0)   
       e = err.number   
       if e = 0 then f.close   
     end if   
     wscript.quit e   
      
   The possible exit codes are:   
     0 = OK. Specified file/directory is movable.   
    53 = Error. Specified file/directory is invalid or doesn't exist.   
    70 = Error. Specified file/directory is not movable.   
   424 = Error. No file/directory given.   
      
   Example usage:   
      
     @echo off   
     setlocal   
     set src=c:\my data   
     set mask=*.doc   
     set dest=d:\my archive   
     rem move files   
     for %%A in ("%src%\%mask%") do (   
       cscript check.vbs "%%A"   
       if %errorlevel% == 0 (   
         rem do file move. e.g.   
         rem move "%%A" "%dest%"   
       )   
     )   
     rem move a directory   
     cscript check.vbs "%src%\subdir"   
     if %errorlevel% == 0 (   
       rem do directory move. e.g.   
       rem move "%src%\subdir" "%dest%"   
     )
