I've seen others host images on Dropbox. Is there a way to find out the user hosting the file?
For example, if I post a Dropbox picture online, can any user find my name or username? Can link it to other uploads?
Thanks
Dropbox links are obfuscated, meaning there is no way to tell the directory structure by looking at the link. Also, contents on the same folder might have name close to one another but their shared link will be different. For example:
/Public/reports/doc1.txt -> www.dropbox.com/s/32nwq9a6y9q74hr/doc1.txt
/Public/reports/doc2.txt -> www.dropbox.com/s/wmveygkiea16sme/doc2.txt
So, there is no way to find link to other uploads (even in the same folder). Also, opening the shared link does not show any information about the host user. If viewer is logged in, it will show the viewer at the corner of the page.
However, the user might be exposed based on the metadata on the files that are uploaded. When user uploads a file, dropbox retains the metadata in that file. So, someone with the link can download the file (along with metadata) and find sensitive user information. For example, image files in these days contains information about the device, geolocation, time of modification etc. This does not give away the user account but can leak other information.

I am not sure if this is really the problem but it seems that Windows 10 is automatically creating a new profile for me with the same credentials every time I restart my computer. I can still log on with my old credentials but some apps like Slack and Dropbox aren't there anymore and needs to be re-downloaded, MS Outlook is requiring me to set up my profile from start with nothing synced, etc. etc. It's treating me like a new user with each login. I am super frustrated.
Thanks.
There is not enough information for sure knowing what is happening. But from my previous experiences, I could assume that what you are seeing is, Windows login you into a temporary profile. This happens when there is something corrupted on your original profile, and windows log you into the last know working profile. After logout, nothing is saved.
Sometimes it is possible to recover the profile, but sometimes it could be impossible. Wherever is the case it is better backup anything that is possible in case that you need to delete and create a new one.
Google for windows temporary profile recovery as they are many techniques depending of the cause. Here are a couple of samples:

I too have the same problem..This problem nos called Temporary Profile Login. You can just follow this YouTube Video Fix Temporary Profile Login Error in Windows 10

Since I am not that experienced with Linux this might be an easy, if not too simple question for you. Recently I met an old friend of mine and I want to exchange some files with him. In fact I could send the files by E-Mail or share them by Dropbox or something like that but I want to make use of Linux and my RaspberryPi.
Here, the RaspberryPi can be accessed via SSH and I want my friend to be able to access one specific directory. The one where I place the files.
I don't want him to mess around in the system. Ideally he should be able to only see this one directory.
Is it enough if I create a user and put the files in his home directory?
Thanks in advance
See this introduction to permission management on Linux.
To answer your Question:
Is it enough if I create a user and put the files in his home directory?
Yes, but it's not a perfect solution because the home folder of an user contains some subfolders.

I like to ask how am I going to copy files from one of my Linux Server Account to other account? If anyone knows how, please help me.
Take a look at the man pages for scp. This is a very useful command that I use rather often at my job.
It works easiest if you are logged into the server that has the file you want to transfer (IMO). The syntax is scp src_file username#remote_host:dst_file, where the text that comes after the : in the second part is the destination path on the other server.
For example, if you have a file called "file.txt" on server1, and you want to put it on server2, you would type:
scp file.txt username#server2.name.or.ip:/home/other_username
or where ever you want to put the file. I would recommend copying the file first to your home directory on the other server as that minimizes issues with permissions, in my experience.
EDIT: If you want to log into the server that is going to receive the file, you can just swap the first and second arguments to copy from the remote server to the local one.

I know google drive has a sync folder now and that most office documents placed within that folder will sync automatically with google drive. However, in order to edit, for example, an excel spreadsheet that has been synched to google drive, I have to convert it to a google doc. That means that any edits I make to the original excel file on my desktop will not sync with the newly created google doc. Is there any app or something that I can use that can sync changes made to an excel file on my desktop (I am using a Mac) to its google doc counterpart in google drive and vice versa?? I'd still like to do most of my edits using the Office software when possible...
Thanks!
As far as I'm aware, you can't.
You'll need to use a different cloud service, or don't convert them to Google docs if you want to use office software. Office software and Google cloud are competing products that do not have direct compatibility.

I'm trying to get some firm handle on how reliable long-term data storage is using Google Docs/Google Drive. Presumably when a file gets uploaded or automatically synced, the transfer is verified using an md5sum -- I see that these are saved as meta-information according to the Google Docs API. And since the file is mirrored to multiple servers, presumably each of these transfers is also verified.
But then the file sits there for years. I don't change it, so no syncing ever gets triggered. Does Google occasionally verify that the md5sum hasn't changed, to protect against silent corruption of the file -- and repair the file if an inconsistency is found? Or is the md5sum meta-information just a static value representing what the file looked like when first uploaded years ago?
I would not worry about this. We can't share the specifics but data hosted on Google is checked against corruption and is also replicated multiple times.
This doesn't prevent you from uploading corrupted data though. So you could potentially use the read-only MD5 checksum field post upload to make sure that the file that you just uploaded to Drive has the correct MD5 if data consistency is critical for you.
