Sharing big files between 2 computers

Hi janime - are you looking for 'free' solutions?

https://www.foldershare.com/ is one option.

You could also consider ftp (file transfer protocol) - though this is a slow solution, unless you have a decent upload speed on both ends.

Other options (which would be 'hosted'):

100mb-1gb

500mb

I was thinking more along the lines of a VPN connection

Choose one 'end' to be the VPN server. I will assume you are running Windows XP. Instructions on creating the server end can be found here:
http://www.onecomputerguy.com/networking/xp_vpn_server.htm
The client end can be configured with the following:

This can be configured with other versions of Windows. Please advise if you need instructions, or you can find most here:

You will also have to forward port 1723 on the router at the 'server' end to the computer acting as a VPN server. Finally on the same router you need to enable PPTP pass-through. This could be called GRE, PPTP or VPN pass-through depending on the router.You can find specific information as to how to configure port forwarding for your router at:
http://www.portforward.com/english/routers/port_forwarding/routerindex.htm
Click on the link for your router and on the resulting page click on the link for "Point to Point Tunneling Protocol"

Once connected you may have problems with name resolution. Try using IP's instead such as  \\192.168.123.123\ShareName

By the way both sites should use different subnets. If one uses 192.168.1.x the other should uses something like 192.168.2.x  Better still is to use something less common line 192.168.123.x


Another posibility is to use the free Hamachi VPN. It requires no port forwarding and is very fast to set up:

Well, thank you guys.  I'm gonna give a try.  Anyways, I'd like to point out that friend of mine is in Europe, he doesn't have much experience with setting up any networks, routers, servers, etc - so basically I'm looking for a simple application. Take a look a DC+ or any P2P sharing software. All you need is just to download "exe" file, get it installed set up the shared folder and you're good to go! The problem is you have to share it with other thousands/million people. I need something simillar - but for sharing between two people only (or let's say 3 at maximum)..

Hamachi above is like that. Very small little .exe and a little wizard to walk you through it. First time will take you 10 minutes, because you have to decide on a user names and such,  after that about 3 minutes  :-)

Then only configure the ftp server ( Bulletproof FTP ) at one end and create the user authetication and at other end install the ftp client like smart ftp or cuteftp and access that shared foder.May be it works.

Hmm, I've installed the Hamachi software but there is nothing about setting up a specific folder for sharing.. Could you help me out - where to find that option?  Thanks.

Enable file sharing as you normally would for access from the local network. Then when connecting, NetBIOS names are not broadcast over a VPN, so best to connect by IP address using the local IP such as \\192.168.123.123\ShareName
If you are only accessing a few computers, or in this case probably one, you can add the computer name of the remote computer to the LMHosts file.  The LMHosts file creates a table of IP's and computer names. LMHosts is located in the Windows directory under c:\Windows (or WINNT)\System32\Drivers\Etc\LMHosts.sam , instructions are included within the file. Any line starting with # is just a comment and is ignored. Open the file with Notepad and add entries for your computers as below;
192.168.0.101      CompName       #PRE
Hit enter when each line is complete (important), then save the file without a file extension. To be sure there is no extension ,when saving enclose in quotations like "LMHosts". Now when you try to connect to a computer name it should find it as it will search the LMHosts file for the record before connecting.

However, you will not likely be able to browse Network Connections and see the remote computer, unless you have a WINS server.
