I created a local web app that just displays images and PDFs on a loop kiosk style. It has a basic Node.js http back end that feeds file paths to client browsers and the browsers use embed elements to display those files.
The issue is that when the client has run through the files provided and is told to reload chrome (It looks to be chrome that's doing it at any rate...) downloads a _Thumbs.db file. This app is meant to be a full screen kiosk and I would rather not have the downloads bar or any downloads prompt be present while it's running the slideshow.
I have disabled all the options for thumbnails on the windows side, but oddly enough it is a chrome download prompt that is the issue.
Can I prevent these files from being downloaded? If-Not any Idea how I can prevent Chrome from throwing a download prompt up?
Thanks in advance.

I want to open files from webpage. For example when we try to download a torrent file it redirects us to utorrent app and it continues it work. I also want to open a local file somehow using OS software. Like a video file using pot player. Is there any possible solution for me ,like making a autorun in pc to run that . Anything it may be please help me.😔😔
I searched and found a solution to open a software using protocol, but in this way I cannot open a file in that software.
Opening a specific file in a specific software would usually depend on passing some URL parameters to the protocol-URL of the app (e.g., opening a file in VSCode would use a URL like vscode:///Users/me/file.html, but this functionality would have to be explicitly handled by the app itself though, so the solution for each app would be different).
Otherwise, if the app doesn't support opening a specific file itself through a URL, you'd have to use some scripting software (e.g. AppleScript if you're on macOS) to dynamically click/open certain programs on a user's computer.
the link acts as a magnet so your torrent application is opened maybe delete torrent for sometime till you finish the project, i know how to open image in local files in html but it will only be visible to you, you can do audio and video files also using <source src="movie.mp4 and on next line `type="video/mp4">
I have strange problem on Chrome for Android with local website.
It works perfect on Firefox for Andorid, but not for Chrome.
On my site here: https://passcombo.com there is download link with a zip file.
What I do is:
download file to local file system (not SSD! - external storage makes
another problem!)
I unzip the package and go to the site in local storage using File Commander
I open the html file with Chrome - only HTML loads, no CSS, no JS, no images, no fonts.
Looks like there is path problem with relative paths?
But firefox works!
Working alternative is Firefox, but there you need to write correct strange path: "file:///storage/emulated/0/..../...html"
But...
Currently Chrome is mostly used on Andorid so it's bad local sites not working :/
It doesn't work opening with file explorer, you have to write the path in the address bar file:///sdcard/Download... or wherever.
JS works with Chrome on local html file in my Galaxy S6.
The only solution I found is to:
[update 2021] use Opera (Firefox did work before recent update!)
copy folder with my html/css/js to local storage
(somewhere)
open the sitewith path like:
[current Opera] file:///storage/0000-0000/MyFolder/index.html
[old in firefox ] file:///storage/emulated/0/myfolder/index.html
where 'file:///storage/0000-0000/' OR 'file:///storage/emulated/0/' is the main path to local storage, and if you copied your folder somehwre deeper then you need to change the 'myfolder' to /somefolder1/somesubfolder/.../ sth
Shame it's the only way to create a web browser app for adroid.
It is possible using a HTTP server app on your phone.
For example the SimpleHttpServer.
Set the "Document Root" in the settings of that app to the folder in which your html files reside. Start the server and you will see a local link.
Click on that link and choose the html file you want to show.
If you declared your assets relatively those assets will loaded, too.
Seems like the only directory Chrome reads local files from is file:///sdcard/Android/data/com.android.chrome/files/Download/
The only solution worked for me in Android is the HTTP Web Server (I used Simple HTTP Server).
Installing different browsers didn't help:
(Apr-2021) I tried installing various Browsers (Chrome, FireFox, even Opera etc.) in Android but none worked. In all cases, when I navigated to the folder containing HTML/JS files using local file:/// URLs ('file:///sdcard/' or 'file:///storage/emulated/0/') browsers only displayed the folders but no files.
When I used the absolute path to the HTML file the browsers used content:/// protocol to
render static HTML content, i.e. it did NOT allow execution of JavaScript code.
In my Android OS version 7, to open a local html file with css and javascript in Google Chrome browser (ver. 64.0.3282.123) I have to open it through an address bar typing as file://localhost/sdcard/, then navigating to the file location. In spite of mention sdcard in the address, it opens an internal storage (and my device has actual removable sdcard as well).
Currently, I am also facing this problem. Chrome does not link to other files on the device, but you can use js and CSS by, using <script> and <style> tags and these will be included in the web page. But, for other files, like image, audio, videos, etc. it can't be done on Android still without any server established by 3rd party apps.
Install a text editor from playstore . Its name Acode
Got to your local file storage , then choose your .html file and press long time.
After press long time on .html file , you will see more (left side of your phone screen)
From more menu, chose open with option
Choose Acode text editor
When html file open on Acode editor, then preview it from Acode text editor.
that's all. It will works 100%.. (sorry for my english)
My chrome packaged app contains a PDF, and I would like to let the user view it. If I open it in the current frame I get the error "Chrome PDF Viewer is not Allowed".
Frankly, the chrome PDF viewer is pretty awful, so I'd rather let the user view it in their PDF viewer of choice anyway. If I disable the chrome PDF plugin (just as an experiment) and I try to open the PDF using chrome.app.window.open, it "downloads" the PDF, and then the user could open it. But this has two issues:
I can't realistically make the user go to chrome://plugins and do that disable
There isn't any browser window, so the user has no idea the download happened
Any suggestions? Opening PDFs that are embedded in my app is kind of a must-have feature for this app.
I've looked at this extensively, and have come to the conclusion that there's no way to get a Chrome App to open a PDF that's local. I, too, have tried data URIs.
I don't think the issue is the PDF support in the window, as it's still Chrome, or the size of the PDFs. Rather, I think it's just an engineering problem, one that might get solved someday.
As for me, I build the PDF in my Chrome App. Since I can't display it, and there's no server to upload it to, I write it to a file of the user's choosing and let the user deal with it on his/her own.
I've got this working, but whether it is a solution for you depends a lot on your use case. The solution has three parts:
Use pdfjs to do the actual rendering.
To get this running in a packaged app, you'd need to do some violence to the internationalization support. And even after you do that, you'll find that some PDFs refuse to load for no apparent reason whatsoever. So don't bother trying to make pdfjs work in a packaged app. Just:
Put your entire app into a <webview> with a persist partition, and use a HTML5 cache manifest to get all your files available for offline viewing.
Yeah, yeah, I know that cache manifests are not cool anymore. But if you can list all your files for use in a packaged app, then you are doing the one case where cache manifests actually work great.
Then use a packaged app to distribute a tiny wrapper around your page with the webview in it.
You'll also get the benefit that you don't have to rewrite your app to live within the draconian packaged app rules (eval, sync xhr, 2GB limit, etc.).
You can see a working example at m.kaon.com/c/ka (visit with Chrome to get the desktop app; if you visit that with Firefox, you'll get access to a hosted app that is using the same tricks). PDFs are down in the bottom "Why Choose Kaon" section.
I am writing a page (html, javascript) that is going to be used absolutely for mobile devices.
This page is going to serve some files (typeof: pdf, doc, docx and many others) that browser doesn't recognize. How can I force browser to give the option of saving file and open it with the appropriate installed app?
I tried _blank but nothing, it opens the page and ... raw data appear (not even a new tab starts).
It sounds like you need to make sure the web server is serving the correct mime-type for your content. For uncommon or forced-download types, it can be served as application/octet-stream.
I am currently creating a Chrome extension (which uses javascripts mainly) that allows users to scrape the images on a webpage and download them. I have finished the link scraping part, and the code will return an array like:
["http://example.com/image1.jpg","http://example.com/image2.jpg"]
But how do I download all of the links in ONE CLICK? I tried listing all photos on a new tab and let the users to Ctrl+S save the page. But this greatly affects the UI and I do not like it. I do not host webpage so server side script may not be working.. Any other solutions?
As far as I know, Chrome extensions technically can't save files to disk like Firefox.
The only way to do this is using NPAPI
Unfortunately, extensions using npapi will most likely not be accepted by the Web Store due to security problems. Of course it'll be okay if you use it for yourself or host the extension on your website.
You can install and examize the code of the following extensions, maybe you can even use the provided npapi too:
