Syncronize FTP


Question:

I have a directory on my desktop pc I'd like to synchronize with a specific directory on my website via FTP. In other words, anytime I add or delete files from the directory on my pc, I'd like a winbatch script to reflect those changes on the specified directory on my website. Is that possible?

Answer:

It's sort of a work-in-progress, but this should get you pretty far, with little effort. You'll probably want to strip out a lot of code, as I developed it to meet very specific requirements. This app is made to run via the task scheduler. Also, the script FTP's from one remote server, to a local computer, then to a remote web server. Confusing as it is, it works really well for me.

FTP File Sync by CowboyDan

;***added function to skip the multimedia directory at wwwroot
;***added log file management that works (email at the begining of each day)
;***changed For loops with ItemCount() to be 2 steps now. 11/13/2006
;***Added file age checking to limit the number of times a file will transfer to one day. (288 times) 11/24/2006
;***file xfer tracking using date check(so that the files only transfer once) 11/28/06
;***---This was done by comparing the date time stamp for the file on the public ftp server vs
;***---the date time stamp for the file on the cms / web2 server
;***ToDo:
;****Clearer Logging.
;****"skip" variable made into a subroutine (like test_file_extension). This would allow for multiple folders to be skiped
;****wishlist: add user specific emailing (maybe keyed of from directory list)
