How to send big files via email?

since you have an google account already, there is no need to add another hoster for your data: upload the file to http://docs.google.com/ as described http://docs.google.com/support/bin/answer.py?hl=en&answer=50092 and share it.

I've experienced this problem very many times. Thankfully, there are a few good solutions. They all involve using file-sharing services. Some of the ones I'm about to list have already been mentioned, but I want to compare them in detail. https://www.hightail.com/ (previously YouSendIt) - upload via the website; up to 50MB; not a lot of control in the free plan; paid plans available https://www.dropbox.com/ - somewhat hard to set up (you have to install it once; afterwards, you can just upload via their site); up to 2GB; very private (to view, you have to give someone a username and password)

7-Zip also has the ability to save an archive into multiple chunks, and you can specify the size of the chunks.

Don't do it. It is: Inefficient (MIME encoding bloats the files like 30%) Insecure Likely to cause problems for people (ie. you're going to hose your friend's work account who is on Exchange 2003 with a 200MB mailbox that's almost full). There's just no good reason for file attachments larger than 25MB.

Try http://ge.tt/ No Flash is required, Easy Transfer of files.

If you're on a mac I really like CloudApp. Drag the file to the menu bar icon and the URL is automatically copied to your clipboard. Paste it in the email and send. http://www.getcloudapp.com/

Lots of players in this space but http://wetransfer.com offers 2GB of space in exchange for your email address. Its currently flash based only.

Another favorite option is File Apartment at http://www.fileapartment.com. Easy to use, fast, no software to download or registration, up to 1 GB, free option, safe, and secure.
