Hi, I've just accidentally deleted Speed Dial bookmarks while synchronized, so they disappeared from the account and all devices synced to it.

Since they were deleted from Opera mobile are there any copies of previous bookmarks in some file stored on PC?

In Appdata/Roaming/Opera Software/Opera Stable I have

• "Bookmarks" 1.914 KB
• "Bookmarks.bak" 1.889 KB
• "BookmarksExtras" 8.893 KB.

The file "Bookmarks.bak" is the less recent among them.

How can I restore deleted bookmarks?
