// In many programs (like Microsoft Word), deletion is often just a save:
// 1. Save data to temporary file ~wrdxxxx.tmp
// 2. Delete Example.doc
// 3. Rename ~wrdxxxx.tmp to Example.doc
// See https://support.microsoft.com/en-us/kb/211632
// So, upon deletion, wait a bit for any save operation to hopefully finalize, then sync.

// the best we can do without mind-reading third-party programs.
