  2. {Functions to use long filenames}
  3. {All functions start with "W32" to distinguish them from 16 bit functions}
  4. {To call a function, use it like a normal function, with one exception:
  5.  the last parameter must be the id value for that function. Example:
  6.  longhandle:=W32FindFirstFile('c:\*.*',finddata,id_W32FindFirstFile);}
  7.  
  8. {VERY IMPORTANT: All these functions work fine on Windows 95, but NOT all work on
  9.  Windows NT:
  10.  - W32SetCurrentDirectory returns true, but does NOT actually change the current directory
  11.  
  12.  all other functions seem to work fine, but test your application on NT before saying that
  13.  it runs fine!
