Upload more than 1400 files at once

Reply Quote

I had observed that I could not upload more than 1400 files(.txt) at once using AjaxUploader feature - "Selecting multiple files".

Is there any limitation with AjaxUploader?

If not, how do I overcome this limitation?

My requirement is that it should not limit number of files to be selected to a specific number. Sometimes, I may need to select more than 5000 files and upload it in one go.

If get the file name to long message, it is the windows system limitation, is not a bug.

What error yo got?
When I tried to select 1897 files at once, then there is no "ShowProgressBar" and no uploads takes place. I renamed the 1897 files to minimal filename and the upload is in progress.

If get the file name to long message, it is the windows system limitation, is not a bug.

How can I convey the same message to the user at runtime if the file upload cannot take place due to this limitation?
I observed that "WindowsDialogLimitMsg" property has value "Unable to select so many files at once. The total file name length cannot exceed 32kb.".
Do I need to use "WindowsDialogLimitMsg" property? If so, how to use it?

Hi sansindia85,

You can set the string to this property directly

uploader1.WindowsDialogLimitMsg = "";

But the property value of WindowsDialogLimitMsg does not get displayed if the Uploader is unable to select mutiple files due to windows limitation.A message should be conveyed to the user. How to do it?

Hi Ken,

I tried the code snippet which you had mentioned.

I had selected 1897 files at once and clicked "Open" button.Unfortunately, I could not get any alert, neither the function "CuteWebUI_AjaxUploader_OnError" gets called or the file upload takes place.

Regards,

sans.

I could able to get the error message for an individual file whose file name is very long.

But, I could not get the same message when I select multiple files (1897) and click open.

After I select those 1897 files and click open, the following things are observed:

1)The upload does not proceed.

2)No error message or dialog gets displayed.

To reproduce the behavior at your end, please try to select more than 2000 files or more with their original filename.
