I have a large file kfx 90MB azw format, and as I use linux I was unable to even open in Cloud reader perhaps due to its size. This was published in 2020.

I downloaded the kindle ebok file to a PC using kindle-for-pc 2.31 then kindle-for-pc 1.17.

The kindle-for-pc 2.31 which failed to be decryped in Calibre 7.5.1 with 1.0.9 DeDRM. then I tried kindle-for-pc 1.17 but it failed to open in Calibre for PC.

I deauthorised the first kindle-for-PC before installing the earlier version, but it failed to open in Calibre for PC.

I then saved the .k4i file and entire My Kindle Content folder and copied it to the linux laptop.

Calibre for linux 7.4 with DeDRM 1.0.9 decrypted the azw file once the .k4i was enabled for the earlier version of kindle. It failed to open in first 5 minutes in Calibre but I converted it to PDF and that completed quickly.
