Azure | Some Files/Folders are not visible in KUDU or SCM site (KUDU File/Folder limit)

Issue

Why my files/folder are not visible in KUDU?
I can see folders/files in my local application but it is not visible in KUDU.
I know those folders are available there because without those folders my application will not work but somehow not visible in KUDU.
When I run "CD Folder_Name" command in KUDU console I am able to get into that folder but it is not visible in KUDU.
I can see those files/folders through FTP but not in KUDU.

Reason

I uploaded 338 items (files + folders) in KUDU and below is the result,

The limit for displaying the number of items is 299.

If you have more than 299 files or folder then some of them will not be visible due to this limitation.

This is by design and can be checked in KUDU code. You can clearly see MAX_VIEW_ITEMS = 300

https://github.com/projectkudu/kudu/blob/0fe7fbe12ce4786aaefa233da6b2c4272578b5f4/Kudu.Services.Web/Content/Scripts/FileBrowser.js#L256

The reason it doesn't display all is that performance becomes really bad with large folders. Thus it uses some algorithm in the backend to decide which files/folder should be displayed.

Solution

An immediate workaround which we can use,

Use “CD Folder_Name” command in KUDU Console.
Use FTP
Use App Service Editor

But still, if you want the folder to be visible in KUDU in spite of limitation then remember “Every problem has a solution in this world”. 😊

Please use following steps,

if you are using chrome browser, go to your scm(kudu) site
open developer tools (F12)
in the console, run window.localStorage['maxViewItems'] = 300 (or any number)

I set the limit to 400.
