PyroTrans is an EuroFile transfer package (client, server and batch mode), that allows users to manually or automatically exchange files between computers which are connected via ISDN, Modem or Internet. The product is targeted at software developers, users and companies who require easy and reliable file transfer, either manually or controlled by other software. The server component PyroServer is typically used in environments who allow multiple users to download files from or send files to the server (e.g. a driver download center) or multiple users to send files (eg. a print shop where customers transmit their Postscript files) . Users are identified by their user name and can be verified by passwords. It can be controlled per user if they are allowed to receive and/or send files. The client component PyroClient can manuall call PyroServers over ISDN, modem or internet or third party EuroFile servers (via a direct ISDN connection). It looks like an Explorer Window and files can be transmitted via drag and drop. The batch component can be controlled by script files or by other software to initiate a connection and do file transfers in an automated fashion, e.g. for a nightly transmission of company data between the comany and branch offices.
