Get onedrive file URL from a the locally cached file

I am looking for a way to derive the OneDrive file URL for a file cached to my local OneDrive folder? The only thing I can think of is hardcoding some root URLS for each of the OneDrive folders I have, but this seems nasty!
Does anyone know of any OneDrive client API that lets query a URL based on the local file path?
My use case:
I am trying to attach to and open instance of an Excel workbook. I used to be able to do this Marshal.BindToMoniker(_workbookPath);
However it appears that Excel is now registering the OneDrive URL in the ROT rather than the local file path. This this happened with the update that brought the new auto-save feature to Excel 2016 I think, that seems to be about the time my existing code broke.
There is a similar unanswered question here: C# OneDrive for Business / SharePoint: get server path from locally synced file

Might want to use the following key instead:
HKEY_CURRENT_USER\Software\SyncEngines\Providers\OneDrive
This includes the following registry values:
UrlNamespace: (SharePoint site URL)
MountPoint: (local driver location)
It does appear to include old values which are no longer synced - but it shouldn't be too hard to check against
HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager
for paths that are being actively synced.

I am also looking at a solution for getting the SharePoint url to a file in OneDrive Synced File Explorer.
I have noticed you get under C:\Users%username%\AppData\Local\Microsoft\OneDrive\settings\Business1{GUID}.ini a mapping between your OneDrive synced folder and the SharePoint GUID
Example:
libraryScope = 1 630c2a866d9c458b81060eff107887ed+1 5 "GUIDEs" "Documents" 4 "https://mytenant.sharepoint.com/teams/team_10000035" "8d4b558f-7b2e-40ba-ad1f-e04d79e6265a" e0266a43caf347238f684bab486f4e51 e0d25dcb1a014f5f86d787984f6327c2 4f86b3e3e54e42e0bb0f7a58eadf0335 0 "" 0 4cde5c00-3fe3-4162-b831-d8ef440e1593 libraryFolder = 0 1 8bbfe07dfeff41cea7ab5da4a554592a+1 1558084235 "D:\DSUsers\uid41890\TenantName\GUIDEs - General" 2 "General" bd0c1b7c-2a1f-4492-8b1b-8e152c9e0c26
You also have this mapping in the registry Computer\HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
From the GUID you could get the path using SPWeb.GetFile(Guid)
If you can make a standalone function given a local OneDrive file path that returns the SharePoint url, I would greatly appreciate you share your solution here.

I have implemented a solution in AutoHotkey see documentation here
It is based on #GWD idea (see comments below) to generate a temporary excel file with the formula CELL("filename") at each sync locations to extract this mapping information to a text file that is then later parsed to do the reverse mapping from local file to SharePoint url.

To browse folder and Create folder in the server and upload files using asp.net

I am Currently working on asp.net i have worked on file upload by uploading files but i want browse a folder not a file and get all files in it and get foldername and create foldername in server and upload files it to server.Pls give me some refernce and help me to do this.
My aim is when i browse that folder all it files present in it should upload .Only files should upload not folder
Note:To browse folder not file.

Actually you are supposed to include a question if you want an answer, but it seems you are completely new to this so here are a few things you should know when it comes to asp.net and folder/file handling:
Your virtual path always corresponds to a local path on your webserver. Since it would be bad to hardcode that you might want to start off by mapping it. (e.g. /uploads/ to _C:\intepub\application\uploads)
"and get foldername"
string localpath = Server.MapPath("/uploads");
"and create foldername in server"
next you can check if that folder already exists, or if not - create it.
if(!System.IO.Directory.Exists(localpath))
System.IO.Directory.Create(localpath))
Keep in Mind though that your IIS-User needs the rights to create new directories
Now that you have made sure that your upload directory exists, you can upload/download files. Here is a good tutorial to get started:
"and upload files it to server"
http://msdn.microsoft.com/en-us/library/aa479405.aspx
"but i want browse a folder not a file and get all files in"
You can do that on the server, not the client. Your asp.net code never executes on the client.
string[] filenames = System.IO.Directory.GetFiles(localpath);
"My aim is when i browse that folder all it files present in it should upload"
That one isn't so easy, sorry. It would pose a serious security risk to users.
Maybe this will point you in the right direction (apparently it works with Chrome)
How do I use Google Chrome 11's Upload Folder feature in my own code?
When it comes to files, directories, filepaths, etc. in general, I would recommend taking a closer look at these classes:
System.IO.File
System.IO.Directory
System.IO.Path

extract file/names from .torrent

I have .torrent file and I want to extract all the file names from that file. I have tried searching but i am not having enough luck.
P.S:
I am writing a simple service which will watch a specific folder to upload my torrent files to my seedbox. Then another service will poll on my seedbox to download that downloaded files. There might be some torrents which i am not intrested to upload so my utility will upload specific torrents. I want to keep log of which torrent got uploaded so that i can fetch respective downloaded folder from my seedbox.
For reference, a torrent file may call Torrent_of_movie_2010.torrent file. But when the Torrent client would download, it will download it in a folder/or a file specified in .torrent file.

here is the simple Gist for you:

Upload and rename multiple files to FTP using asp.net

We are creating CMS, in which we want to have the option to upload multiple files to FTP server. The steps are
Open FTP connection
Click browse - Select multiple files - Click upload to FTP
Create a folder on the FTP server
Rename the selected files and upload them to the folder
Close the connection
It will be good if it shows the status of the upload.
We are using asp.net with C#. Any sample code will help. Is there any good components available. I can spend max of $150 to buy a component.
Please help. Thanks in advance.

First of all, you should use an open source CMS and improve the code to your needs, don't try to reinvent the wheel!
Second, there is no need to spend money, plenty of solutions out there ...
you can use, for example Uploadify to pass user files to your server, then using any FTP Example upload the files to the FTP and delete them from the server upon success.
if you don't want to have the "middle men", just upload directly to the FTP
string name = Path.GetFileName(UploadControl.FileName);
byte[] data = UploadControl.FileBytes;
using (WebClient client = new WebClient()) {
client.UploadData("ftp://my.ftp.server.com/myfolder/" + name, data);
}

Getting the full file path when using a file upload control

I wrote some code to upload files to amazon S3, if I put a full file path manually It successfully uploads the file from my computer. What I'm trying to do is use a file upload control and store the full path in a variable so that I can use it for my amazon method. Ive read everywhere it seems that the browser won't let you get the full file path for security reasons.
How can I get the full file path? Should I just store the files on my webserver and point my amazon method to the server path, and then use the file upload control to tell it what the filename is? I wish I could just do a straight shot to amazon...

First we have to save the file path and then we take it from
string filepath=Path.GetFullPath(UploadFile1.FileName.toString());

I came across this link which has a great tutorial and even gives you a working sample project. (this is different from the code that the .net SDK includes...) http://aws.amazon.com/articles/774?_encoding=UTF8&jiveRedirect=1

We can't take full path in HTML or JS as it violets security so whenever you try to see the path it shows fakepath
so to resolve this issue you can make a seprate folder and you can store the uploaded file there and in the code you can take that folders path as default and use it as a absolute path.
You can get the full path using Python Tkinter but it is limited for desktop app.
