Windows 10: Desperate Help Needed: How to check if files have been modified?

Hi all, I DESPERATELY need some help here.

I've been using Dropbox for over 2 years now and I've been sharing my Dropbox account with other users. I've got some .PDF files stored in my Dropbox folder and I'm VERY worried that these .PDF files have been modified by another Dropbox user.

This is my question: How can I check if my files in my Dropbox folder on my local HDD have been edited at all?

Thank you for any help!

:)

Perhaps you have to type netstat -a -n -o

NETSTAT [-a] [-b] [-e] [-f] [-n] [-o] [-p proto] [-r] [-s] [-x] [-t] [interval]
-a Displays all connections and listening ports.

-b Displays the executable involved in creating each connection or

listening port. In some cases well-known executables host

multiple independent components, and in these cases the

sequence of components involved in creating the connection

or listening port is displayed. In this case the executable

name is in [] at the bottom, on top is the component it called,

and so forth until TCP/IP was reached. Note that this option

can be time-consuming and will fail unless you have sufficient

permissions.

-e Displays Ethernet statistics. This may be combined with the -s

option.

-f Displays Fully Qualified Domain Names (FQDN) for foreign

addresses.

-n Displays addresses and port numbers in numerical form.

-o Displays the owning process ID associated with each connection.

-p proto Shows connections for the protocol specified by proto; proto

may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s

option to display per-protocol statistics, proto may be any of:

IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.

-q Displays all connections, listening ports, and bound

nonlistening TCP ports. Bound nonlistening ports may or may not

be associated with an active connection.

-r Displays the routing table.

-s Displays per-protocol statistics. By default, statistics are

shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;

the -p option may be used to specify a subset of the default.

-t Displays the current connection offload state.

-x Displays NetworkDirect connections, listeners, and shared

endpoints.

-y Displays the TCP connection template for all connections.

Cannot be combined with the other options.

interval Redisplays selected statistics, pausing interval seconds

between each display. Press CTRL+C to stop redisplaying

statistics. If omitted, netstat will print the current

configuration information once.

 

You could look at the date modified and compare this to your local backup perhaps?

If they should never have been modified then the creation date and the last modified date should be the same (which will make things easier). You can see this by right click > properties > details

 

Assuming you have a 100% "good" version of your file(s) and another one that you want to verify, use HashMyFiles to compare the hashes of the files (a sort of digital signature). If there are different, something must have changed.

 

Thanks so much for your replies!

I've got another similar issue, but it doesn't involve Dropbox.

I've got one .PDF file that is located across a few different devices and HDD's and I just wanted to know if there's a way I can check if it's been altered by anyone? In other words, it's supposed to be the same .PDF file with the same content, but how can I check if anyone of them have been altered?

Thank you!

 

This may be old fashioned but you can just use the old DOS file compare command fc from a command prompt. Type fc /? to see the options. Also see http://www.howtogeek.com/206123/how-...ommand-prompt/

 

Thanks, but how can I be sure that'll definitely tell me that the .PDF hasn't been changed? I just want to know that the pages and text inside it hasn't been changed because it's an e-book in .PDF format.

Is there something else I can try with a GUI?

 

I did a Google search for "visual file compare" and found this https://en.wikipedia.org/wiki/Compar...mparison_tools

That should keep you busy for the rest of the day *Smile

I still think fc is a quick and simple test.

 

Try Beyond Compare from Scooter Software. It may be just what you need.

 

Like I said, I just want to know that the content within the .PDF file is unchanged like the text and the number of pages.

Is there an app in particular someone can highly recommend for me?

 

Hey guys, this is a really important issue for me so I'd love to hear more opinions from the experts on here!

 

I'm sure there are other users who could help me out. Could this thread be moved to a different forum please?

Thanks!

 

Did you try any of the previous suggestions? If so what was/were the result(s)?

 

We have given you various solutions to tell if files have differences. Didn't these work for you?
