Occasionally I want to transfer files from my work PC and home PC or vice versa. There are a number of ways of transferring large files:
1. Dropbox - 2GB limit but the files will also be copied to other devices connected to my dropbox account.
2. Skydrive - files cannot be >100MB, could be split using 7-zip
3. www.transferbigfiles.com - Again, 100MB limit
I found the ideal solution - www.JetBytes.com - you open it in a browser session on the source PC, click on upload file and it will give you a download link. Open this link on the destination PC and it will stream the file from the source PC - I get decent speeds and can download a 200MB file in about 20 minutes.
I'm not sure how secure it is, I think it's based in Russia so if you have any concerns best to encrypt the file - you can use 7-Zip or WinRar to encrypt files and not apply any compression.
