@DevTester425 the notification should appear when attempting to open a resource which cannot be read (#9950), is it the case in your example?

theia/packages/filesystem/src/electron-browser/file-dialog/electron-file-dialog-service.ts

Lines 93 to 101 in 68dbea5

	protected async canRead(uris: MaybeArray<URI>): Promise<boolean> {
	const inaccessibleFilePaths = await Promise.all((Array.isArray(uris) ? uris : [uris]).map(
	async uri => (!await this.fileService.access(uri, FileAccess.Constants.R_OK) && uri.path || '')
	).filter(e => e));
	if (inaccessibleFilePaths.length) {
	this.messageService.error(`Cannot read ${inaccessibleFilePaths.length} resources: ${inaccessibleFilePaths.join(', ')}`);
	}
	return !!inaccessibleFilePaths.length;
	}

Same issue here on linux with version 1.2.0,
I choose open file with ctrl + o, pick the file in explorer, the file is displayed in editor but a notification appears

I tried with a test folder containing only one text file that is rw, the notification still appears

ls -larth
total 12K
drwxr-xr-x 10 me me 4,0K 17 sept. 11:08 ..
drwxr-xr-x  2 me me 4,0K 17 sept. 11:08 .
-rw-r--r--  1 me me   24 17 sept. 11:08 test.txt

Also the path of the problematic files should be displayed in the notification as per the code sample posted above (the ${inaccessibleFilePaths.join(', ') part).

It is never present in my case.

Nothing in the logs (I can see info, warn and errors in the logs so I guess the problematic part is not logged or is at debug level).
