I tried to search for a solution but until now nothing could not find any solution to split the files of a folder into zip files of 2 mb. And when I try to send in a single file the software of the error me derived to the size of the zip.
How can I split the contents of a folder into 2 mb files? The operation timed out sending e-mail with zip file.
I'm developing an application to apply web cameras for forest and forest monitoring.
This application records photo frames and then we can make a video of these photo frames but I'll explain:
The application when we load the green button it starts to take photo frames, after having executed them and load in the red box to stop the software to take photo frames, then it does a zip file of these photo frames and need send them by e-mail and then delete all of their folder.
Well my problem is not in the software itself everything is working fine, but the problem starts when the software before deleting everything I want to send the zip file to the email but of course these files are wider than allowed.
Then give me an exception 'The operation timed out'
I've tried it in several ways, but with no success.
I was wondering if there is any way to overcome this problem.
