The following requirements must be met on the server and the client-side in order for WebDAV integration to be functional in Kentico.
Editable file size limit
By default, WebDAV editing is only functional with files smaller than 50 MB.
In case that a user needed to edit larger files using WebDAV, they would need to go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters in their Windows registry and adjust the FileSizeLimitInBytes key to the required value.
Forbidden characters in file names
WebDAV does not support uploading and editing of files whose names contain the following characters: %, &, +. Uploading and editing of such files using WebDAV may result in unwanted behavior and is not recommended.
