The following text lists specific behavior of the system when WebDAV Browse mode is used. These specifics are by design and can't be influenced or solved by a workaround.
The maximal path length in Windows file systems is 250 characters. Therefore, if you have deep indentation in your content tree, folders and files that would have the path to them longer than 250 characters are not displayed on the network drive.
As explained in step 5 of the Example of Browse mode editing topic, you may experience delays when updating files in grouped attachment fields or file fields. The original file will be present along with the new one for about 1 minute. If you refresh displayed content of the folder after the interval, the file should disappear.
The same problems may be experienced when deleting a file without appropriate permissions. The file will not actually be deleted, but it will not appear in the folder for the 1 minute interval until Windows cache is refreshed.
It is not possible to upload or create document attachments and files using the file field based on files that have zero file length. On attempt to do so, the following behavior can be expected by-design:
When uploading a zero-length file under the attachments folder, a temporary attachment is created. It is not visible in the UI or on the network drive. If your try to upload a file to the same folder, an error message saying that the file already exists will be displayed (asking you if you want to overwrite it).
When uploading a zero-length file under the content folder, a standard CMS.File document is created, while it only has a temporary attachment in the file field. The document can be seen both in the UI (as a document in the content tree) and on the network drive (as a folder which can't be deleted using Browse mode). The temporary attachment can't be seen in either of the two. If you try to upload a file to the same folder, an error message saying that the file already exists will be displayed (asking you if you want to overwrite it).
Please note that in WebDAV Edit mode, uploading of zero-length files is possible without any problems or limitations.
