Dhaval,
I guess you could try uploading the file to a different file name (say with a different extension or folder) and then add an After Put command that renames/moves the file. Like Russel’s suggestion, I also recommend looking at nsoftware’s adapter as an option; it’s pretty complete. It actually does contain an option for uploading the file with a temporary extension and automatically rename it once the upload is complete, which is pretty useful in cases like this.
