cron hangs. What to do?

Question

linux

I made synchronization with 1C on the site via cron using the link, a link of this format
"/usr/bin/wget ' site.com/index.php?option=com_store&task=import.ru... '>/dev/null 2>&1" , and the synchronization itself occurs through the export.xml file.
After the cron synchronization, each time it creates a file in the root of the site with the name of the link, as a result, after a few days of the script's operation, the place is clogged. As a result, synchronization stops, and for some reason the export.xml file is deleted.
How can this matter be simplified so as not to climb into the manager every week?

Answer 1

It was done, as advised by Pavel, through auto-deletion.
