File Upload - Need To Check File Size
I'm having a problem with the fact that I want to allow image files to be uploaded to a remote web server, as the hosting package the web site is on is IIS6 and has a default file upload size limit of 200kb. As it's a shared hosting package, the default limit cannot be changed for me unfortunately.
Anyway - i need to check the size of the file being uploaded, so i can notify the user and prevent them getting the default Microsoft error message page. The problem is that I can't implement a server side size check which works, using either Request.TotalBytes or load.getFileSize (with "load" being an object of my loader class). It seems that I can't carry out any of these operations when the file size is too large.

I am developing an web application, it should has the function to upload file from client computer. The uploaded file size can be limited within 10 MB.
But I dont know how to check the size of the file on client-side. Server-side size check is not enough, because it can not be checked until the whole file is received while the server resource(cpu,memory etc) is wasted.

I got a script for uploading files that sets its file size limit to 10240kb. The line in that script Code:
Const MaxFileSize = &H100000
has an equal size of 10240kb. Any idea why &H100000 is equal to 10240kb and how do I set it to less or greater than using such hexa type like value?

I had my server run win2K SP4 running an ASP site that uses ABCUpload and all was working fine. Today I have found that we can no longer upload files greater than about 4Mb.
I think way back when I set this site up I had to change a setting some where in windows that allowed the site to accept file greater than 4Mb. Does any body know what this setting is and where I can find it.

I have a couple of images that the user can upload, but I want to limit the size to 512kb(most of them will come from a digital cam).
Is there a way to check the file size before the page submits? ie a javascript function that i can call before submitting the page?

I have code that loops through a directory reading files..
now the problem is that files are constantly being uploaded and I only want the file system object to read those that are finished being uploaded.
How can I check the properties of the file to see if it's in middle of being written before i read the file?

I would like to add a facility to my web page which allows users to upload basic files (word, excel, text, gif, jpg etc) to the server.
I know there's a facility to do this using HMTL forms, but I don't know how to handle the file on the server side.
What I think I need is an ASP file running some code to manipulate the filesystemobject, allowing me to receive the file and store it in the filesystem on the server. It would be nice to access some of the file properties too (name, type etc).
I've seen a few custom components online which allow you to do this, but I can't depend on installing them. I need to be able to script it myself.

How do I find out the size of a file. I can get listing of files in a
directory but I cannot figure out how to get the file size also.
Here is what I have so far.
<%
Set MyDirectory=Server.CreateObject("Scripting.FileSystemObject")
Set MyFiles=MyDirectory.GetFolder(Server.MapPath("test"))
For each filefound in MyFiles.files
Response.Write filefound.Name & "<br>"
Next
%>
I don't have any books for reference here. Can someone point out a good
online source?

i am using the file type input and an asp upload component to save the file from client machine to server machine. if user type the file name or path that doesn't exists, the upload component still create a file on the destination but that file is empty. Now, how can i determine the size of the file saved on destination.
OR
its alternative is that can we restrict the user to type the path and file name. i mean the text field is disable and only browse button is used to select a file.

I made a image upload a while ago, but too many people submits too large images (this is no problem, since ASP Upload won't upload too large images) but people gets frustrated when their images are not uploaded!I want to do so that you can't submit the form if the pictures are too large. I was thinking of doing a asp functions to check the file size and then pass the result to a javascript function, which will then alert the user and denie him to submit the images.I know how to do the javascript part, but I don't know how to check a local file's size with asp? I'd appreciate if someone could help me! Thanks.

Is there a way to capture the current size of an uploading file as its being uploaded to a directory, so I can produce a loading bar?
I've tried using GetFile but that only displays when the file has been fully uploaded.

I have a site that allows a person to log in and get a list of files to download for them. If the file size is under 65MB then everything is fine, they click the download button and the save box pops up. But if the file is larger than 65MB the page sits and processes until it times out. I can't figure it out becaus a 64MB file loads immediately for download while one slightly larger hangs up.

I used to have a little ASP file (classical ASP) that would show me the total file size used per directory. I didn't need it for many years and now that I do I seem to have lost it.
Does anyone have an classical ASP file/script that will loop through your filesystem and shows the total Mb's used per directory? I could write it myself I'm sure, but if someone has a script like this ready it would save me quite some time.

I have a folder that has a batch of leaflets in it, these are PDF files. In my application I have a list of courses and one of the fields has the name of the file.
Is it possible, without automatically having to add them by hand, to grab the file sizes and use them on a page or insert into the relevant db field?

I am building and intranet and i need to check if a file exist in a folder on the network. The folders are in the R drive, the web server is on the same network as the other servers. I have tried this code below but I can only check the files on the website.
Set fs = CreateObject("Scripting.FileSystemObject")
if fs.fileexists("filename")=true then
Response.Write "Exist"
else
response.write "Doesnt Exist"
end if
set fs = nothing

Here is part of my code:
If fs.FileExists(Server.MapPath("filename.htm") Then
set f=fs.OpenTextFile(Server.MapPath("filename.htm"))
If f.ReadLine <> "" Then
First, I check to see if the file exists. If so, then I open the file for reading. Then, I read the first line to see if it equals "".
The problem here, though, is that if the file is empty, I'll get a "Input past end of file" error. So, how do I check to see if it's empty without reading the lines?

I'm using freeASPUpload and trying to create logic to prevent uploaded files from overwriting previously existing files.
The file I'm modifying is too long to post here. It can be downloaded from www.freeASPUpload.net.
I've been trying to insert this code in a number of places in the tester file.
If fso.FileExists(Request.Form("attach1")) then
Response.Write "Filename already exists. Please rename before up load."
Exit Function
End If
I've tried many alternatives to "Request.Form("attach1")". Everything from a variable name like "fileName". All of it only creates errors....

I need to make a check for file type at client end, ie allow only files that are images to be uploaded and prevent the others. I tried using the HtmlInputFile.Accept Property, but it somehow doesn't seem to work.
moreover, it claims to support only few browsers. Also, javascript in itself, gets very dirty, if i start making validations for every thing. Does ASP.NET support any control which can cause these validations? what is the most elegant way to do this?
