Hi Angus, 

  

Greetings from Syncfusion support. 

  

We have validated your reported query in File Manager component. To validate the reported issue, we have prepared a MVC sample in 19.1.64 package version and hosted it in IIS. But, unable to replicate the issue you are facing in File Manager control. Please find the sample from below link. 

 

https://www.syncfusion.com/downloads/support/directtrac/general/ze/MVC_FileManager-1789026085  

  

We understood that you have been facing some issue in File Manager component, but in order to replicate the issue in our end we need some additional details. 

  

1.      Whether you are facing this issue on initial rendering or while performing any file operation? 

2.      Whether this issue only occurs while hosting the sample? 

3.      Steps followed in your end to host your application. 

4.      File Manager related code snippets and video footage of issue. 

5.      If possible, share us a live hosted link or reproduce the issue in the above shared sample. 

  

These details will help us to serve you better.

Thanks for your reply.

Above is my live host in window serivce(testing environment and will be available one week). And also attach with file manager controller.

It works well in IIS or Kestrel console but not in window service.

I'm just make standalone web application without IIS that can be hosted in window service or run like normal program.

I found something that work. Because my project folder was put in D directory and it can not accessible by window service or something (I don't know). But I put my project folder in my document folder, it works fine.

Thanks for your patience and I think I must find some way to work around with window service host.

[angus chao]

finally solve the problem. It was all about path and in documentation 

this.operation.RootFolder(this.basePath + "\\" + this.root);

I've change above line to 

this.operation.RootFolder(Path.Combine(this.basePath, this.root));

Thanks you very much.
