Users can transfer files in chat during the session.
Zoom deletes files sent via in-session chat when the session ends.
Enable send files via in-session chat in your Video SDK account portal settings and configure the following settings.
- Only allow specified file types - Select to allow only specific file types and enter the file extensions in the text box, separated by commas.
- Maximum file size - Select to limit the file size to 2048 MB.
Check if the file transfer feature is enabled.
Swift
Objective-C
let ret = ZMVideoSDK.shared().getSessionInfo().isFileTransferEnabled()
BOOL ret = [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] isFileTransferEnabled];
Get the list of allowed file types that you can transfer.
Swift
Objective-C
let ret = ZMVideoSDK.shared().getSessionInfo().getTransferFileTypeWhiteList()
NSString *ret = [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] getTransferFileTypeWhiteList];
Get the maximum file size to transfer.
Swift
Objective-C

unsigned long long ret = [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] getMaxTransferFileSize];
Send files to all users in the current session.
Swift
Objective-C
let ret = ZMVideoSDK.shared().getSessionInfo().transferFile(filePath: String)
ZMVideoSDKErrors ret = [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] transferFile:self.filePathTextF.stringValue];
Send files to a certain user in the session.
Swift
Objective-C
// Locate the user that you would like to send the file to.
let receiver: ZMVideoSDKUser
// Send file directly.
let ret = receiver.transferFile(filePath: String)
ZMVideoSDKErrors ret = [_receiverUser transferFile:self.filePathTextF.stringValue];
Cancel sending files.
Swift
Objective-C
// getCurrentSendFileObj is a user-defined method, to retrieve the sending file.

Start receiving files.
Swift
Objective-C
// getCurrentReceiveFileObj is a user-defined method, to retrieve the receiving file.

}
Cancel receiving files.

File transfer callbacks
Be sure that you have set up a delegate for callback events to receive file transfer callbacks.
Get notified when you transfer a file.
Swift
Objective-C
func onSendFile(_ sendFile: ZMVideoSDKSendFile!, status: ZMVideoSDKFileTransferStatus) {
// Get the transfer status of the file and the file content here.
}
- (void)onSendFile:(ZMVideoSDKSendFile *)sendFile status:(ZMVideoSDKFileTransferStatus)status
{
// Get the transfer status of the file and the file content here.
}
Get notified when you receive a file from other users.
Swift
Objective-C
func onReceiveFile(_ receiveFile: ZMVideoSDKReceiveFile!, status: ZMVideoSDKFileTransferStatus) {
// Get the transfer status of the file and the file content here.
}
-(void)onReceiveFile:(ZMVideoSDKReceiveFile *)receiveFile status:(ZMVideoSDKFileTransferStatus)status
{
// Get the transfer status of the file and the file content here.
}
