Required Registry Settings for Using Mapped Centerbase WebDav Drive

Several common issues experienced when using the Centerbase mapped drive features with large files (>50 MB) on Windows PCs can be solved by updating your registry settings. These include issues saving larger PDF files or your drive disconnecting.  

If you are using the Centerbase mapped drive feature to transfer files larger than 50 MB or experience disconnections, follow the steps in this KB article to correct them.

NOTE: Also, see the article regarding the best way to map your drive as well. Disconnected drives are common if when you map your Centerbase drive, you tell Windows to remember your username and password. While this works on locally connected network drives, it will cause the Centerbase drive to continually be disconnected.

Warning: Editing your registry can damage or disable your system and is intended for advanced users. Always backup your registry before making edits.
