Description

Syntax

system.file.fileExists(filepath)

Examples

This basic example shows how the fileExists function is used in its simplest form:

if system.file.fileExists("C:\\temp_file.txt"):

   system.gui.messageBox("Yes, the file exists")

else:

   system.gui.messageBox("No, it doesn't exist")

This code uses the fileExists function, along with other system.file.* functions, to prompt the user to confirm that they want to overwrite an existing file.

filename = system.file.saveFile(name)

if filename != None:

   reallyWrite = 1

   if system.file.fileExists(filename):

   overwriteMessage = "File '%s' already exists. Overwrite?"

      reallyWrite = system.gui.confirm(overwriteMessage % filename)

   if reallyWrite:

      system.file.writeFile(filename, "This will be the contents of my new file")
