Re: Doubt on partial files
Hi, is there a change to distinguish an incomplete transfer and a complete one on server side, generally? http://dict.leo.org/ende/index_de.html#/search=distinguishsearchLoc=0resultOrder=basicmultiwordShowSingle=onAs far as I know a ftp client opens the data channel for uploading a file (passiv mode). The ftp client signals the end of data transfer by closing the data channel. But there is no check, if the file is complete!!! Some ftp clients like filezilla support to abort an active file transfer by just closing the data channel. So there is no chance to distinguish an incomplete transfer and a complete one on server side, am I right? For that reason you need an additional acknowledgment from the client. For example the client could transfer a file with extentsion '.tmp' an rename it, if it's transfered completely. Right?

Re: Doubt on partial files
Hello Edson, Even though you might achieve that by using a FTPlet, I think a better solution is that the Ftp client itself renames the file after a successful upload.

I'm new on FTP Server project, and after reading documentation I could not find if there is a option to deal with partial uploads. What I would like to do is that received files keep extension .tmp or .partial until finished. For example: client send file meuarquivodedados.dat ftp server start received file with name meuarquivodedados.dat.tmp or meuarquivodedados.dat.partial client finish sending file normally ftp server renames file from meuarquivodedados.dat.tmp to meuarquivodedados.dat Is there a option for that? Other option I'm evaluating is to use a database server as repository, and then set a flag as complete when finished. Any guidance on that? Please, consider me a complete novice in this topic (some FTP, SFTP and Linux knowledge, but little - to none - Apache FTP Server knowledge so far), ok?
