## Troubleshooting WebDAV

ownCloud uses SabreDAV, and the SabreDAV documentation is comprehensive and helpful. See:

- SabreDAV FAQ
- Webservers (Lists lighttpd as not recommended)
- Working with large files (Shows a PHP bug in older SabreDAV versions and information for mod_security problems)
- 0 byte files (Reasons for empty files on the server)
- Clients (A comprehensive list of WebDAV clients, and possible problems with each one)
- Finder, OS X’s built-in WebDAV client (Describes problems with Finder on various webservers)

## General Troubleshooting

Note

The data directory on the server is exclusive to ownCloud and must not be modified manually.

Disregarding this can lead to unwanted behaviours like:

- Problems with sync clients
- Undetected changes due to caching in the database

If you need to directly upload files from the same server please use a WebDAV command line client like cadaver to upload files to the WebDAV interface at:
