To fix a problem, JetBrains technical support team may request a wide range of information about your system or configuration (e.g. logs or CPU snapshots).
Files under 10 MB in size can be attached right into the tracker issue (if you do not want the attachments to be publicly accessible, limit the attachment visibility to jetbrains-team user group only using the Visible to option under the comment field).
You can also send small files (up to 2 MB) via email: firstname.lastname@example.org (or any other support/sales email you are communicating with). Files up to 20 MB can be attached to the support ticket in the online form or later on any step of communication with our technical support engineers. Please do not forget to mention product name, exact product version in the request (along with other information which might help us to faster understand and resolve the problem you are experiencing).
If the file is over 10 MB, you can upload the archived files to ftp://ftp.intellij.net/.uploads and let us know the exact file name. If you receive the permission denied error on an upload attempt, please rename the file. It's OK that you do not see the file listing on the FTP.
The FTP accepts standard anonymous credentials: username: "anonymous", password: "<your e-mail>".
In addition to usual, unencrypted connections, TLS ones are also supported.
In case of access issues, time-out errors, etc. please try using passive FTP mode.
You can also upload a file via https://uploads.jetbrains.com form and let us know the exact file name.
