File: Maximum allowed size is 50MB.
Description:
Privacy:

If the data you need to attach is more than 50MB, you should create a compressed archive of the data, split it to 50MB chunks, and upload each of them as a separate attachment.

To split a large file:

  • On *nix platforms use the split command e.g. split -b 50MB <my_large_archive> <my_split_archive_prefix>
  • On windows use WinZip or a similar utility to split the large file
