The default appearance of the File Manager can be customized with your own icons by using showThumbnail property.

The following example demonstrates how to add a custom icon in the largeicons view.

import { BrowserModule } from '@angular/platform-browser'
import { NgModule } from '@angular/core'
import { FileManagerModule, NavigationPaneService, ToolbarService, DetailsViewService } from '@syncfusion/ej2-angular-filemanager'
import { Component } from '@angular/core';

@Component({
    imports: [FileManagerModule,],
    providers: [NavigationPaneService, ToolbarService, DetailsViewService],
    standalone: true,
    selector: 'app-root',
    styleUrls: ['./app.component.css'],
    template: `<ejs-filemanager id='file-manager' [ajaxSettings]='ajaxSettings' [showThumbnail]='showThumbnail' height="375px">
    </ejs-filemanager>`
})
export class AppComponent {
    public ajaxSettings?: object;
    public showThumbnail?: boolean;
    public hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
    public ngOnInit(): void {
        this.ajaxSettings = {
            url: this.hostUrl + 'api/FileManager/FileOperations',
            getImageUrl: this.hostUrl + 'api/FileManager/GetImage',
            uploadUrl: this.hostUrl + 'api/FileManager/Upload',
            downloadUrl: this.hostUrl + 'api/FileManager/Download'
        };
        this.showThumbnail = false;
    }
