The simplest and most reliable method I have encountered is

return not empty(sys(2000,tcFile))

This function will RELIABLY check for the presence of the file string in tcFile, It does not create arrays, and does not require any further searching thru the array. If the file is found on the drive/directory as specified in tcFile sys(2000) will return the name of the file, if it is not found sys(2000) will return '', therefore if the file is found this function will return True else False.
