file_exists

Definition: bool res = file_exists(string name)
Description: Check to see if a file or directory exists

name: filename to check (absolute or relative to the current directory)

Returns: true (1) if it exists, false (0) if it does not.
pwa/p2js: Not supported.
Comments: If you want to know that something is actually a file and not a directory, just use get_file_type(filename)==FILETYPE_FILE.

Both forwardslash ('/') and backslash ('\\') are handled for all platforms.
Example: 
if  file_exists(`C:\Program Files (x86)\Phix\p.exw`)
and file_exists(`C:\Program Files (x86)\Phix\`)
and file_exists(`C:\Program Files (x86)\Phix`) then
    puts(1,"all three are true!\n")
end if
if file_exists("backup") then
    -- (get_file_type("backup")==FILETYPE_DIRECTORY may be better)
    puts(1,"there is a backup folder in the current directory")
end if
Implementation: See builtins\pfile.e (an autoinclude) for details of the actual implementation.
