I. Intro 

You can send and download files and folders in chats.

II. Steps 

Send files and folders

There are three ways to send files or folders in a chat:

Note: Sending folders in a chat is only supported on the Feishu desktop app.

Click the + icon on the right side of the message input box, and select Docs to send Feishu documents.

Click the + icon on the right side of the message input box, and select Local File or Local Folder to send local files or folders.

Drag and drop local files or folders to the chat to send them.

Download files and folders

There are three ways to download files and folders you've received in a chat:

Click the Download icon in the lower-right corner of the file/folder to download it.

Click the folder to enter the file manager and click the ... icon next to the file you want to download, and select Download.

To download multiple files in the file manager at once, hover over a file, select the files you need, and click Download at the bottom of the page.

View the download location of files

Click your profile photo > Settings > General, and scroll down to Downloads to view the download location of files/folders.

To change the download location, click Change.

Use LAN to transfer files

When two users on the same LAN send files that are larger than 20 MB, the option to transfer through LAN will become available.

Note: This function is currently only available on the Feishu desktop app.

If LAN transfer is available, the sender can click Transfer using LAN.

The recipient can click Accept and select the download location to start the transfer.

The sender can check whether Feishu is allowed in the inbound rule settings of the Windows firewall. If not, set Feishu to allowed, and try LAN file transfer again. 

III. FAQs

100 GB. 

What is the maximum folder size that can be transferred through chat? 

100 GB. The folder cannot have more than 10 levels of subfolders, and the number of subfolders cannot exceed 100. 

Why can't I use LAN to transfer files?

Make sure the file being sent is not smaller than 20 MB, and both the sender and recipient are online at the same time.
