All hosting accounts / providers have some sort of file count limit. The file count limit to there to ensure your hosting server isn't abused or overtaken by other users. So we have enacted file count limits on every account in our network. Please see below for more information about this:

• Base-Host – 50,000 Files
• Tera-Host – 100,000 Files

Those are the two set limits for file count on these plans. You can see a daily updated report of your file count in the /reports folder. You may download and open this file, and in there you will be able to see your current usage.
