原因：
Any files or folders with names which start with a full stop character (.) are treated by the system as hidden files. Hidden files will not be visible in most FTP programs unless the FTP program has been specially configured to display them.
There are a number of pre-installed hidden files in your account. In most cases it is helpful that these files are kept hidden as it is rare that you need to access any of these files directly. Keeping them hidden makes the list of files displayed by your FTP program more manageable and should make it easier for you to find those files and folders which you really do need to access.
对于CuteFTP 8.0 Professional，我们可以这样设置：
1、在“站点管理器”中，在你要设置的站点单击右键。
2、一次进入“属性->动作->过滤”：
勾选“启用过滤”，
勾选“启用服务器端过滤”，
“远程过滤”框中填入参数“-a”。
3、依次确定。
再次链接该站点时，原来好多的隐藏文件就显示出来了，当然，也包括我们要找的.htaccess文件。
PS:如果你不是很了解LINUX和FTP的话，千万不要乱删那些隐藏的文件。他们可能是系统生成的。
