Share your files for support

Our support team may need to examine a file in order to provide support for opening it. If you have a relevant file that led you to seek support, we encourage you to share it with us when you reach out for help. If the file size is less than 5 MB, you can attach it to your email. However, for files larger than 5 MB, we suggest using alternative methods to send it, as email service providers may have restrictions on the size of attachments. This will ensure your email reaches us successfully.

Please be aware that we take the privacy and confidentiality of our users very seriously, and take great care in managing the security of our data. All information provided to us, including any file attachments, data, and knowledge, will be kept confidential and private. After a support case has been closed, we will not retain any copies of files or data that were voluntarily shared with us.
