I'm going to create a web app that's going to run locally on the user's computer.
First off, the user has downloaded a JSON file that ended up on "my download files" locally on their computer.
So they are going to browse to e.g myportal.local and there they are going to select the downloaded JSON file and also they need to choose a local location (directory).
To simply the workflow
Go to myportal.local in the browser
Choose in the form the JSON file
Choose a local path on the machine
Press submit and other scripts will parse and download things to the chosen folder.
Steps 1,2 and 4 is not a problem, it’s step 3 on how to choose a local destination.
It isn't possible to do this directly in the browser.
Since the HTTP server is running on the same computer, you could use server side code to examine the structure of the computer's file system and generate a user interface in HTML for the user to pick directories with.

I have a web application that triggers actions at the server side which result in the generation of data files.
The so generated data files are stored within a folder at drive different from the one where the Web application is.
What I tried so far is to create a shortcut (Windows Server) next to the Index.html, where the shortcut points to the folder at the second drive.
This solution does not appear to work:
If I copy the data file to the same folder where the Index.html file is and enter navigate to the URL httm://127.0.0.1:324324/Data_File.xlsx I get the file downloaded.
If I enter httm://127.0.0.1:324324/MyShortcut/Data_File.xlsx (where MyShortcut points to a folder in drive D) the attempt fails.
How can I achieve this?
The need to access files in the different drive is essential.
You need to configure your server to serve that folder under different location. The only reason you are able to see your app and access that folder is cause server is set up to serve it ATM, not because you are making the right calls from the front or cause the front is asking nicely.
Don't know what Windows server version you are using and IIS version that goes on it, or are you even using IIS (you most probably do) but depending on what you use you need to do something in a lines of this:
IIS7 config
What you probably wanna do is create virtual folder in IIS. Try looking into it, then if you fail ask a question with proper tags according where are you stuck.
I don't see how this is connected to front-end at all so front end tags wont get you far.
EDIT:
Oh, in that case get a second file server running for that folder? This should be the fastest way, use what you can from this list: list
I am just a beginner in HTML (and soon JS), and I was wondering, once my website is complete (an html file made in either Sublime or Notepad), how do I get that website to other people? If I wanted to make a website eventually with my online portfolio of videos and images, how would I get it out to people?
Uploading website files are one of the very first steps users have to take in order to publish their creation on the Internet. This tutorial will provide a generalized example on how to upload a website using one of three basic tools:
What you’ll need?
Before you begin this guide you’ll need the following:
Access to the control panel of your hosting account
Your website’s files (preferably compressed in a .zip or .tar.gz
format archive)
(Optional) An FTP client and FTP login details of your hosting
account
Option 1 – Upload Your Website via Hosting's File Manager
Navigate to your control panel’s Files category and open File
Manager
After that, go to the public_html directory, which is the root
directory of your domain (for example http://www.domainname.com/).
Your files should be uploaded there. The directory may also be changed depending on what URL you want it to be accessed from. In case
you want the content to show up on
http://www.domainname.com/something/ your content would need to be
located in public_html/something directory.
To start uploading, right-click with your mouse and select Upload
Files option.
To unzip your archive, right-click it and press Extract.
Once the content is located in your desired location, you will be able to access it using any browser.
Option 2 – Uploading Your Website via FTP
Some users prefer using an FTP client, such as FileZilla, SmartFTP, CoreFTP, or any other in order to upload their website. In this example, we will use Filezilla.
Firstly, you will need to get your FTP details.they
are located in your control panel’s FTP Access section. If you are not sure what your FTP password is, you can easily reset it by pressing Change account password section.
Open FileZilla and input your FTP connection details into the fields
at the top of the program, then click Quickconnect.
Once you are connected to the FTP server, use the file browser on
the LEFT side of the program to find your website’s files on your computer. After you have found your website’s files, use the file the browser on the RIGHT side to open your public_html directory on the hosting server. Once you have done this, you can simply drag-and-drop files from left to right and they will be uploaded to the server.(OPTIONAL) Similarly, you can upload a compressed archive via FTP by dragging-and-dropping from left to right. You will also need to extract it via File Manager. Refer to the “Option 1 — Uploading your website via File Manager” part of the tutorial above for instructions on how to extract archives via File Manager.
Option 3 – Uploading Your Website via cPanel’s File Manager
Click on the File Manager icon, located under the Files category.
Once inside the File Manager, open the public_html directory.
Click Upload after entering the public_html directory.
You can click “Select File” to select a singular file, or simply
drag-and-drop your file to the outlined area.
Once the upload is complete, return to the File Manager and you will
see the uploaded archive in your public_html directory. Right, click
the archive and select Extract to extract the archive.
If you receive a prompt asking to specify the location the archive
should be extracted to, make sure to specify /public_html.
The archive is now extracted, all files should now be located inside
public_html. Navigate back to public_html and see if the files were moved successfully.
Your website should now be fully uploaded and accessible via your
website’s URL. All that remains is to access your website and check if everything works correctly. Simply type in your domain name in
your browser, such as http://www.domainname.com/, and check if your
website works to your satisfaction
you have just learned how to upload a website. As you may see, you can upload a lot of files at once via an FTP program more easily, however, each file will be uploaded one-by-one. As a result, it may take a long time for each file to be uploaded separately, so it is still strongly advised to create a compressed archive of your files before uploading them.
On the other hand, the File manager is useful for uploading one or two files quickly, since you do not need a separate program for the File manager to work and can update your website on-the-fly, while working on other tasks inside your hosting control panel.
i'm using my beaglebone as my host device that's running lighttpd. my beaglebone is running another program that creates .log files.
I want to be able to connect my beaglebone to a laptop, open up the webpage that lighttpd's running and choose the .log file to review and be able to review it.
I assume this means I would have to
1) upload .log files to lighttpd server
2) html/js script to choose from these log files and view
I currently have a javascript/html file that lets me choose a file and displays it - but only on the local server (so from my laptop instead of the specific beaglebone logs folder)
If this is the right way to go about it, can anyone help me get started with some links/info? I've never worked with lighttpd/javascript before.
if not, point me in the right direction.
the current tutorial i'm looking at is http://www.alecjacobson.com/weblog/?p=1645&cpage=1#comment-311815 to create the javascript/html file
You can have a folder in on the beaglebone which contains logs and you can list the contents of the directive with mod_dirlisting.
https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModDirlisting
You can use mod_alias to map the folder into your web server docroot.
https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModAlias
You should probably restrict access to view the logs using mod_auth.

We are building a web application to help people organize their local files; it has a text input field in HTML5/JS.
Ideal functionality: user clicks on the text box and it lets them select a file or folder on their local drive, which passes the path of said file or folder to our server.
Is there a JS API or HTML5 method to find a path to a local file and folder?
Due to browser security, you cannot get the file location from a FILE input. For that same reason, you will notice that FILE inputs always get reset to blank after a postback. This is because the browser will not persist or expose the file path as a security measure.
I have a web page containing a list of pictures urls (can be more then 1000 items) and I want to enable a button for the user to click and download all of the files to the local hard drive.
The download process should ask the user for a directory to save the files in and then go ahead and download all files to that directory (if possible, creating sub directories inside). This should be done with a single user confirmation for the whole download process and avoid display the browser save dialog for each file.
Is there a way doing that? I am aware I can't use the standard HTTP protocol for the downloads and have to write some kind of control to do the job. The page is written in asp.net.
Downloading to the server, packing and sending to the user is not possible. The download has to be originated from the client machine.
You should update your question to include the requirements from your comment, because they make a huge difference. If the server cannot retrieve the files, because he doesn't have the right permissions, your only option is to run the code on the client side. There are several options how to do this, mostly depending on the clients and your coding skill:
Flash (Not sure about the security aspect of writing to the local file system, though)
Java Webstart (Disadvantage: Clients need to have the Java runtime installed)
Browser plugin/extension (Disadvantage: You can only support a subset of browsers and the page will not be immediately usable, as the plugin or extension needs to be installed first)
In all cases, you will have to write a tool, that retrieves the URL list from your server and starts downloading it.
