Abstract:
1. A method for folder transfer based on instant messaging (IM), comprising: performing, by an IM sender, a version-compatibility check with an IM receiver; receiving, by the IM receiver, from the IM sender a transfer request for transferring a folder-to-be-transferred, wherein the folder-to-be-transferred contains a plurality of files; receiving from the IM sender folder information of the folder-to-be-transferred; determining a receiving folder corresponding to the folder-to-be-transferred on a predetermined storage location; determining files-to-be-transferred from the plurality of files corresponding to the folder-to-be-transferred based on the folder information; sequentially sending one transfer request for each of the files-to-be-transferred to the IM sender through a same network connection; receiving the files-to-be-transferred sent sequentially by the IM sender through the same network connection; and storing the received files-to-be-transferred in the receiving folder; wherein, performing, by the IM sender, a version check with the IM receiver further includes: when the version of the IM receiver supports folder transfer, sending, by the IM sender, the folder-transfer request; when the version of the IM receiver does not support folder transfer, informing, by the IM sender, the IM receiver that the version is too low to support the folder transfer and stopping sending the folder-transfer request; and when the IM sender is unable to obtain the version of the IM receiver, sending, by the IM sender, the folder-transfer request.
