Aura HD Two strange GUID txt files have appeared on my Kobo

Nick Payne · 01-15-2018, 05:40 PM

Aura HD with current 4.7.10413 firmware. When I go to "My Books" this morning (sort order is set to Recent), there two entries on the first page, both with the title "Id" and author "Unknown Author", and both plain txt files 37 bytes in size. When I have a look at either of them, they both just contain a single GUID/UUID (see http://guid.one/guid for an explanation). I have no idea where these came from - I only ever sideload books using Calibre, and I don't use the Kobo desktop application at all.

When I view details for either of them, it shows:

Publisher: (1/13/18)
Language: English
File Size: 37 B
File Format: txt

When I attach the Kobo to my PC and mount the internal memory and SD card as drives, I can see that these two "books" correspond to two files named Id.txt in the root folder of both drives - the contents of each file are the same GUID as I see if I open the file as a book on the Kobo.

Any idea how these appeared and whether I can safely delete them?

Move them to your computer and if you find nothing wrong, you can then delete them.

Do you run any sort of indexing program on the PC? This sounds like the sort of thing added by an indexer or similar to identify the devices for searching.

From the Kobo device point of view, deleting the files is safe. I'll be interested to see if they reappear after the next connection.
