Greetings!
Fresh install of v.1.2.10
Learning how everything works before I build a shop with it
(I've played with Zen Cart, Open Cart, Presta, so I kinda know my way around.)
I'm finding AbanteCart Cart to be very user friendly. I appreciate not having to mess with code or core files for simple changes

My issue:

I am assuming, perhaps wrongly, that when I do a data export, there should be a pop-up that lets me choose a folder on my computer to place the downloaded files.
I can access the file, but only by retrieving via FTP.
Within the system/data folder there is a tar file: export_02052017_113239.tar that contains a file: export_02052017_113239, but no extension to the file such as csv.. etc
And a file folder: export_02052017_113239 that DOES contain the csv file

These are the errors I found in the error.txt file:
2017-05-02 11:34:00 - warning: 
AbanteCart core v.1.2.10 file_get_contents(): Filename cannot be empty in <b>/xxx/xxx/xxx/core/lib/targz.php</b> on line <b>168</b>

App Error:  AbanteCart core v.1.2.10 Error:

Error: cannot to pack /xxx/xxx/xxx/xxx/system/data/export_02052017_120257.tar.gz

Any suggestions? I am comfortable editing files as long as I am told what to look for and what to replace/correct.

Thanks!
