Code Examples

Example #1

# 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")

Example #2

# 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")
