I have asked this question so that they can respond that it is possible to create a shortcut for a file that is in the cloud, this access will be created in the device memory, what is the purpose of this: My application has integrated a function to upload a file to the cloud and then run it from a system application like player, gallery, among others, but without having to download anything, but from an application that is installed Installed on the device (nothing external). Thank you very much.
You may want to check Create a shortcut to a file. As mentioned,
To create a shortcut instead of a file stored in Drive, use the files.create method of the API and make sure you set the MIME type application/vnd.google-apps.drive-sdk. Do not upload any content when creating the file.
However, for Google Drive Android API, you may want to check Creating Files for more information.

I am trying to read files from my music directory on my PC.
I have tried doing it with the node.js file system module, but it is not working. How do I get it to work?😢
Just a late follow-up. It is possible to read and write files using HTML5 with the FileReader and saveAs(). The browser will open a file dialogue and let the user choose the file, so the user is aware of the file access. It is not possible to read or write to a file without the user's attention.

As said by #flame in a comment, it's just impossible, because the browser never have access to the visitor's disk (do you imagine the security issue if it was the case ?).
Vue.js is a Front-end framework, so the application it produces only have access to what the browser has access to.
I want to read the content of a text file (serves as a key) stored inside a USB mass storage automatically when the user is authenticated by his matching username and password for that website. It's like the textfile(key) is the extended authentication.
I think this needs to can be done by a (1) native program? or an (2) applet? What do i need to study? Can someone give me an overview for the process to make this possible?
Quite good in web tech but not with native app.
You cannot access USB mass storage devices through chrome.usb as they are claimed and handled by the host operating system.
Instead you could use the chrome.fileSystem API, but the user will need to select the file. Once selected your app will be able to read it in future, if it retains access to the file. See the API documentation for more details.
If you want this only for Internet Explorer, You can create an Active X. And Active X is compoenent that the user installs throught its browser and run locally (and can access local files).
Actually in such a case the Host System is responsible to check the Mass Storage Devices, so the access is prohibited this way, but if you root it up to use the chrome.fileSystem.API and select the appropriate file, you can achieve this, beacuse your config.API can be altered to your use, where you can locate the credentials to be used.(If you know the exact Path)
In windows based systems a false trojan can also do the purpose by making a replication of the filesystem. Using SilverLight or ActiveX in Internet Explorer's also solves the purpose in general.
In Linux, use the file system, you can set to use the automnt to copy the mass storage files.
Why not try building a .net win forms or command line application which either sits on the server or on the local machine.
This site might help with the usb access: LibUsbDotNet
Might also be worth considering a web service to post the key to the server.
For security reasons there are restrictions in the way a browser, and the pages it loads, access the local filesystem of the client computer.
Is it safe to assume you only require this to work on a specific browser? As Ben said, please share more details about your requirement for a more comprehensive solution
Let's say i have a list of files. When I click on one it will get downloaded and saved into the app's isostore. Then it's opened in the default viewer/editor on the windows phone like this:
Windows.System.Launcher.LaunchFileAsync(file);
But when I make some changes to the file and want to save it, it can't, because it's a read-only copy of the file. Is there some way to get write-access to the file or else some public/shared (iso)store that every app has access to? The goal is to download the file, edit it and upload it back to the server.
Per the Windows Phone documentation, the Windows.System.Launcher.LaunchFileAsync API is not implemented for the Windows Phone platform:
Windows Phone 8: This API is not implemented and will throw an
exception if called.
In regards to saving the file so that it can be accessed by other applications, this is not possible, unless the file you are dealing with is a photo, in which case you could use the Media Library API.
I am trying to create a custom control for updating a List on a Sharepoint site that only allows Sandbox Solutions to be added.
I've read a few threads on uploading attachments, but they all seem to involve doing it from the server machine (Using a file stream to read a local file).
Is it not possible to use Javascript or something to pass a file through to a Sandbox'd webpart??
The answer, it seems, is no. You cannot.
I am testing a Google Chrome notebook. Whenever I download a file it goes to a folder called "File shelf" which is somehow connected to my Gmail account. Is it possible to access this folder on a "normal" system running any browser? I did not find how to do it yet. In general, is there a description on how to manage this folder: delete, copy to external storage (USB), etc?
The 'File shelf' is not connected to your Gmail. It's a place on the SSD. If you click 'Ctrl-M' you will get a folder with all the files on your local SSD.
Once you are in the folder - right click will give you the options to delete/rename each file.
If you want wish to do more with this new File API - here is a post I've wrote on it.
Good luck.
