Вот что сказали по поводу ограничения на файлы больше 512 КБ:
Hello,

Thank you for contacting our Technical Support Department.

I would like to inform you that we do not remove files larger than 512 KB. The information on hosting101.ru must be incorrect.

Here you can check the limitations we have set for files:

File Quota - The file quota (the maximum amount of files to be hosted in a single web hosting account) is different for each web hosting plan. The Business and Starter web hosting plans are entitled to host maximum 150,000 files and the Corporate plan - up to 300,000 files. The Enterprise plan allows customers to host up to 450,000 files. All other plans are allowed to host 50,000 files.

Disk Space & Traffic - Free Hostia offers generous amounts of disk space and network bandwidth. Customers must not allow other websites or hosting servers to link to files stored in their hosting accounts, and thus steal network traffic. In order to escape unjust distribution of the resources, as well as possible sharing of illegal content, Customers are not allowed to use their hosting accounts as a remote storage server only or solely for the purpose of sharing (un)archived images, programs or sound files. At least 80% of all files and/or total megabytes used (including MP3, WAV, RA, GIF, JPG, ZIP, RAR, but not limited to these file types) in each hosting account must be a part of actual, active website(s) content, i.e. all content files must have corresponding HTML or PHP files that link to them. Audio, graphics and/or video files must be must be under 25% of the current web hosting disk usage and must never exceed 50 GB in size. Furthermore, such media files may amount to no more than 50% of the customer's total monthly traffic usage. Upon request, each Customer must be able to prove that a given file is a constituent part of an actual page and not only stored on the server within 24 hours of the request. If the client fails to react within 24 hours after the request and does not remove the file/files in question, or if the apportioned traffic quota continues to be used for such purposes - the Provider reserves the right to suspend the account and/or to remove the aforesaid content from the server. In such cases, refunds are not applicable and the money-back guarantee is no longer valid..
