You can share any file that is saved on your phone or external memory! Each file can be up to 100MB in size. If you are on an older version of hike you might be able to share Image, Audio and Video file formats only and the file size is restricted to 15MB in size. If you receive a link to the file, it may be because that your current version of hike does not support the file shared or the size is bigger than the supported size. Don't worry, you can upgrade to the latest version or tap on the link to use a web browser to download this file.
