Using the File API Functionality

You can perform various file system operations with JSFL scripts. Some functionality may have different results on computers running Mac OS X. Tables 1 and 2 provide a complete rundown of what you can do with the File API. For your convenience, I've cross-referenced the actual function that will perform the operation you require.

Table 1. Working with Files
To do this Use this function
Create a file FLfile.write()
Write to a file FLfile.write()
Add to a file FLfile.write()
Read the contents of a file FLfile.read()
Delete a file FLfile.remove()
Copy a file FLfile.copy()
Determine the existence of a file FLfile.exists()
Get the size of a file FLfile.getSize()
Get the date a file was created FLfile.getCreationDateObj(),
FLfile.getCreationDate()
Get the date a file was modified FLfile.getModificationDateObj(),
FLfile.getModificationDate()
Find out if a file is read-only FLfile.getAttributes()
Find out if a file is hidden FLfile.getAttributes()
Find out if a file is a system file FLfile.getAttributes()
Make a file writable FLfile.setAttributes()
Make a file hidden FLfile.setAttributes()
Make a file visible FLfile.setAttributes()
Make a file read-only FLfile.setAttributes()
Table 2. Working with Folders
To do this Use this function
Create a folder FLfile.createFolder()
List the contents of a folder FLfile.listFolder()
Delete a folder FLfile.remove()
Determine the existence of a folder FLfile.exists()
Get the date a folder was created FLfile.getCreationDateObj(),
FLfile.getCreationDate()
Get the date a folder was modified FLfile.getModificationDateObj(), FLfile.getModificationDate()
Find out if a folder is read-only FLfile.getAttributes()
Find out if a folder is hidden FLfile.getAttributes()
Make a folder hidden FLfile.setAttributes()
Make a folder visible FLfile.setAttributes()
Make a folder read-only FLfile.setAttributes()
Make a folder writable FLfile.setAttributes()

Note: All the File API functions can be used in JSFL scripts that are executed on a computer with Flash MX 2004 7.2 installed. Unfortunately, most of the File API methods do not function correctly when running under earlier releases of Flash MX 2004.
