I have a free account and cannot share certain files. Why?
Free accounts come with certain limitations with regards to the sharing abilities. These include, but are not limited to: limits on number of users that can be added to a share, number of public links that can be created, length of link validity, and prevention of sharing of executables and other possibly malicious files (trojans, viruses, phishing,…) and file types (zip, rar, exe, apk, html, etc).
These limits apply to all kinds of shares and access via means other than official Koofr applications - links, Add people, WebDAV.
When blocked files or files of blocked file types are inside a shared folder, those files will also be unavailable.
Limits do not affect account holders ability to upload, access and download files in their own account through official applications.
