# Error when importing Collect Mobile data

Asked by sophie on 2023-06-07

Hi, I have created a Survey using Open Foris Collect and imported it into the Collect Mobile. After filling up the survey, I backed it up and then exported it to internal storage, after which I tried to upload it to the Foris Collect and was given an error message: "zip file is empty". 
I have followed the manual for both the Foris Collect and Mobile, and most of the attribute types are used in the survey, so I am not sure what seems to be the problem.
help is much appreciated!

Dear Sophie,  
Can you check if the file you have exported from Collect Mobile is really empty or not?  
Stefano Ricci (me) from our team will contact you to your private email address (please check also the spam folder) so you can share with me the file to better understand this problem.  
Many thanks,
