However, this is not where you should place your web site files. Only files you wish to be made available via FTP should be maintained here. The exact location of this directory can be found in your welcome letter. This includes .cfm, .cfml, .cfm, .asp, .php, .pl, etc. If the file is a binary file, it must be copied in binary mode.
Binary files are .gif, .jpg, .exe, .ra, .wav, etc.
There are many excellent FTP clients. Yes, you can. However, you can only setup annonymous accounts to read files, NOT to upload files. This is for obvious security reasons. If you need annonymous accounts to be able to upload files, you will need to look at our Dedicated and Colocated service offerings.
