Method of sharing data in a network, characterized in that said network comprises a plurality of devices using a plurality of different network resource sharing protocols, said method being implemented by a proxy device (220, 221) having a file system, said method comprising the following steps: reception, from a first network device, of a request for registration of said first network device for using said network, said proxy device (220, 221) obtaining, from said first network device and during said registration, information allowing identification of a type of operating system and a type of network resource sharing protocol used by said first device; determination, as a function of said type information, of a type of network resource sharing protocol to be used by said proxy device (220, 221) for giving said first network device access to data shared by other network devices; creation, according to said determined type of network resource sharing protocol, of a first directory in said file system of said proxy device (220, 221), said first directory being destined to be an access point for said proxy device to data shared and stored by said first device; transmission to said first network device of an application comprising instructions adapted to said operating system and said network resource sharing protocol used by said first device; execution of said application by said first device, said application creating, in said file system of said first device, a second directory comprising a storage space for said first device where said first device can store data to share with other network devices, and a third directory giving access via said file system of said proxy device (220, 221) to data shared by at least one other network device. reception, from a first network device, of a request for registration of said first network device for using said network, said proxy device (220, 221) obtaining, from said first network device and during said registration, information allowing identification of a type of operating system and a type of network resource sharing protocol used by said first device; determination, as a function of said type information, of a type of network resource sharing protocol to be used by said proxy device (220, 221) for giving said first network device access to data shared by other network devices; creation, according to said determined type of network resource sharing protocol, of a first directory in said file system of said proxy device (220, 221), said first directory being destined to be an access point for said proxy device to data shared and stored by said first device; transmission to said first network device of an application comprising instructions adapted to said operating system and said network resource sharing protocol used by said first device; execution of said application by said first device, said application creating, in said file system of said first device, a second directory comprising a storage space for said first device where said first device can store data to share with other network devices, and a third directory giving access via said file system of said proxy device (220, 221) to data shared by at least one other network device.
