Hello Rifat,

You have posted only this one post to the forum; this one. 

You also opened a ticket in which I asked you to move your topic to this forum.

When you post you inquiry to this forum, please be sure to include the information that I asked you for in the ticket that you opened as well as a step by step list of the steps that you are taking to try and import a file to a collection. Please be sure to be as detailed as possible with your steps.

Regards,

Billy
