in PB we have a function like this below, would need an O2 equivalent

Code: [Select]

'======================================
' check if folder exist
 FUNCTION FolderExists(BYVAL FolderSpec AS STRING) EXPORT AS LONG
 FUNCTION = %FALSE
 IF ISTRUE PathFileExists(BYVAL STRPTR(FolderSpec)) THEN
    FUNCTION = %TRUE
    EXIT FUNCTION

END IF
END FUNCTION

Hi Chris,

This page lists all the file management functions

https://msdn.microsoft.com/en-us/library/windows/desktop/aa364232(v=vs.85).aspx

I would suggest using FindFirstFile

Code: [Select]

uses corewin

function FileExists(char*fi) as int
===================================
WIN32_FIND_DATA fd
sys h
h=FindFirstFile fi,fd
if h>0 then
  FindClose h
  return 1
end if
end function

print FileExists("t.o2bas") 'file
print FileExists("ChrisC") 'folder
