> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

The following text lists specific behavior of the system when WebDAV Browse mode is used.

## Maximal path length

The maximal path length in Windows file systems is 250 characters. Folders and files with a path longer than 250 characters are not displayed on the network drive.

## Windows cache delays

As explained in the [Example - WebDAV browse mode editing](https://docs.kentico.com/k10/managing-website-content/configuring-the-environment-for-content-editors/configuring-webdav/webdav-browse-mode/example-webdav-browse-mode-editing.md) 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 original 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 a 1 minute interval until the Windows cache is refreshed.

## Zero file-length limitations

It is not possible to upload or create [page attachments](https://docs.kentico.com/k10/managing-website-content/working-with-files/page-attachments/attaching-files-to-pages.md) and files using the file field based on files that have zero file length.

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_ page is created, while it only has a temporary attachment in the file field. The page can be seen both in the UI (as a page 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).

> **Info:** Note that in WebDAV Edit mode, uploading of zero-length files is possible without any problems or limitations.
