According to the log file from FileZilla, I'm using much less than my 10K files (286/10000)
12:43:32 Response: 552-286 files used (2%) - authorized: 10000 files
If you mean I can only upload 10K files from one IP address, I'm currently posting from a coffee shop, which is on a different IP address so that shouldn't be the problem.
Also, the 3% over the space allowed is showing falsely. The files are much smaller than that.
I THINK what is happening is that when I overwrite a file that already exists, it adds that much to my used amount without removing the amount the original file took up, effectively doubling how much space it's taking up.
So, I upload a 20MB file and i'm using 20MB, then I overwrite that file, and it's using 40MB, then I overwrite it again and it's using 60MB, etc.
So eventually, I have a 20MB file that's taking up much more quota than its actual size.
I deleted the files in question and it only removed their total size, so I'm still way over what I'm actually using.
