Questions tagged [file-watcher]

A utility or library to perform actions when files are updated, added or deleted.

Common issues for file watcher utilities include

  • How to determine when files being added are fully available (IE: If a file is being FTPed to a directory, has the FTP process finished?)
  • How to notify interested consumers that a file has been updated/added/deleted
  • Scheduling issues such as whether the file watcher runs continuously or every xx seconds or minutes.
  • Whether a file is moved/archived after processing
  • Whether multiple input files that match a wildcard can be processed concurrently.

If your question is about the .NET component FileSystemWatcher also include the tag . For the Qt toolkit QFileSystemWatcher class also include the tag .
