File Watcher 1.0

File Watcher - monitor a file system and react when changes to the directories or files it contains occur You can use the File Watcher application to monitor a file system and react when changes to the directories or files it contains occur.
This makes it possible for you to quickly and easily launch business processes when certain files or directories are created, modified, or deleted. For example, suppose you and a group of coworkers are collaborating on a document that is stored on a shared directory on your server.
Using File Watcher, you can program your application to watch for changes to the contents of that shared directory. When a change is detected, the component can run procedures that notify each of the group members via e-mail.
File Watcher is designed to watch for changes within a directory, not to changes to the root directorys attributes themselves. For example, if you are watching a directory called c:ftp, the component will monitor changes within the directory but not changes to the root directory itself.
You can configure File Watcher to watch either an entire directory and its contents or a specific file or set of files within a given directory. The File Watcher raises an event whenever a file or subdirectory within the specified root directory is created, deleted, renamed, or changed in some other way.
The types of changes that the component monitors include changes in the files or subdirectorys attributes, size, last write time, last access time, and security settings.
Although some common occurrences, such as moving or copying a file, do not correspond directly to an event, these occurrences cause events to be raised.
When you copy a file, the system raises a Created event in the directory to which the file was copied but does not raise any events in the original directory. When you move a file, the server raises two events: a Deleted event in the source directory, followed by a Created event in the target directory.
Each change to a file in a directory raises a separate event. If a user makes multiple changes to a single file, the application raises a separate event for each change.
For example, if you are watching a directory that contains five files and the security permissions for all of the files suddenly change, you will receive five Changed events. If the user renames and assigns new security permissions to each of those files, you will receive 10 event notifications — a Changed event and a Renamed event for each of the five files.
Main features:
- Created — raised whenever a directory or file is created.
- Deleted — raised whenever a directory or file is deleted.
- Renamed — raised whenever the name of a directory or file is changed.
- Changed — raised whenever changes are made to the size, system attributes, last write time, last access time, or security permissions of a directory or file.
