Re: Storing Images?

Hi RedHair,

Is the FileSystem object of classic ASP only able to work to local file
system?

Use the classes in the System.IO namespace. This includes Directory,
DirectoryInfo, File, FileInfo, and a number of others.

Btw, even we have a separate centralized file server for file storage
only, when
the number of directories and files grow up very large, the disk I/O is a
issue, how
to solve this problem? add new file server and distribute all files to all
file servers
equally?

Where do you think your database stores data? In the file system. Therefore,
if you're going to have enough files and folders in the file system to slow
down the disk I/O, it would have a similar (but worse) effect on a SQL
Server.

Now, SQL Server uses memory for caching, which cuts down on IO usage. But if
you were accessing enough files on the disk to cause an IO issue, the SQL
Server would have either memory issues, due to the caching of these image
files, or, if the memory is throttled down, IO issues, or both.

So, all things being equal, I would still recommend using the file system.

Is there any built-in .NET class for ASP.NET to access remote file system
directly?
or I need to code a customized class and use it via ASP.NET?

If store images in file system, is there any limitation of total file
number
in a single folder?

You've got to be kidding. While the answer is, of course, yes, the number
is astronomical. Take a look at your own current file system under
Windows, for example.

Btw, if the web site is a web farm, how to store image to a centralized
file system and retrieve them later?

In a Web Farm, all the servers are part of the same domain. Therefore,
you can use UNC paths to the files, as long as each machine has
permission to access those folders.

File System. Database is definitely a *lot* harder, not easier, and has
a performance hit.

Generally, if the images need to be catalogued, you can use a database
to store meta-data about the images. Sometimes, however, you can use a
folder and/or naming scheme to store the necessary meta-data.

Hi all,

Just wondering whats everyones prefered method of storing images ?

1) File System
2) Database (SqlServer) (Seems to be easier, but has a performance
hit)

Appreciate some insight!!!

Cheers,
Adam
