New laptop, Fire HDX issues

[renzii]

I've been using Calibre for a while and I love it so much that if there's ever a need for a brand ambassador, my name should be at the top of the list. It has seen me through a Nook Simple Touch, Nook Colour and now to the Fire HDX.
In that time, I've gone through 3 laptops and seen my library grow to over 15000 items.

My present laptop is a Lenovo i7-4510U CPU @ 2.00 GHz 2.60GHz, with 8.00 GB RAM, 64 -bit operating system, x64-based processor, running Windows 10 home. At present there is 21.8 GB free on the local disk, Drive D.

Now I don't actually know what all that stuff means, but my brother gave it to me as a gift and I'm grateful. As an avid reader, the first thing I did was to export my Calibre Library (save to disk), to my external hard drive and downloaded and installed Calibre 2.50.1. I was able to read and send books to my sisters' Kindle reader and Fire 7. But my HDX has presented several issues, see the error messages below.

FIRST THIS ONE.

Failed to get children from device: hr=2147942402 facility=7 error_code=2 description: The system cannot find the file specified.


Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 87, in run

WPDError: Failed to get children from device: hr=2147942402 facility=7 error_code=2 description: The system cannot find the file specified.

AND THEN THIS ONE.

File "site-packages\calibre\gui2\device.py", line 503, in _books

It sees my device, but claims it can't communicate with it. I'll be grateful for any help. Thanks in advance.


PS Also I've opened the Fire's internal storage using Windows Explorer, and I've noticed my books , all AZW3 are in the Documents folder, not in Books. I've read on various treads that this isn't right, but I've no idea how to fix it and I've always been able to see and read my items so far.

But I have 36.4 GB of free space on my Fire...

But is TEMP on disk D?

Unless you have made changes to the Standard Environment

or ADD a nee Environment variable CALIBRE_TEMP_DIR (sets the temporary directory used by calibre) with the location to use

As a teacher myself, I get what you mean about doing my own homework, but really, I don't understand what you've written...

Calibre use the TEMP folder defined by the OS (unless you override).
That is typically on C:


Open a command prompt type

SET

you should see (somewhere in the results)

SystemDrive=C:
SystemRoot=C:\WINDOWS
TEMP=C:\DOCUME~1\xyz\LOCALS~1\Temp
TMP=C:\DOCUME~1\xyz\LOCALS~1\Temp

That tells you where Windows has your TEMP and TMP set

Google setting Windows Environment variables (your OS version)

[renzii]

This?

SystemDrive=C:
SystemRoot=C:\WINDOWS
TEMP=C:\Users\renee\AppData\Local\Temp
TMP=C:\Users\renee\AppData\Local\Temp
USERDOMAIN=RENZII
USERDOMAIN_ROAMINGPROFILE=RENZII

I see that Drive C is called Windows8_OS (C) and apparently has 759 GB free

I've found Calibre in the Program Files (x86). Am I ok so far?

all looks Normal


Your Anti virus is (over) protecting your temp folder.

Try a temporary disable (caution: don't surf/download anything during this time)

It that works, visit you A/V provider to find out how to allow Calibre in

That memory error refers to being out of RAM not hard disk space. Changing your temp directory will not affect it. The first error refers to a problem with enumerating files on the device -- I suggest you try resetting your Fire, that usually fixes this class of problems. But note that resetting your device will remove all content from it.

[renzii]

By resetting, do you mean allowing Calibre to configure it, or should I de-register it with Amazon and then start again? BTW, thank you for all the quick responses...

[kovidgoyal]

No I mean reset the device back to factory defaults. Just google reset kindle fire to get instructions.

[AnemicOak]

To factory reset the Fire (will erase everything)...

Settings ---> Device Options ---> Reset to Factory Defaults

Thank you for all your tips, but two resets later, I'm still stuck. Is doesn't seem possible my library is now too big? I've never had any issue before...

Switch to the 64bit version of calibre. Uninstall calibre and install it again from http://calibre-ebook.com/download_windows64
