Hello,

I wonder if you can help me, or point me in the right direction. I have been trying for several days to create a lua script to run in the Task Scheduler and:

1. Recognize when a file has been uploaded to a specific directory
2. email that file to my email address
3. Erase the file

I have written several batch files that accomplish this, but none of them will run from the Task Scheduler Program Execute Window (I have tried both bat and exe files)

The only thing even slightly unusual about the script is that, since the uploaded files are coming from a video camera which is motion-activated, the files are named Lobby-xxx-xxx-xxx where the x's are day-date-time stamps relating to the event. That means that the script can never know in advance what the exact name of the file is that has been uploaded.

Any advice or reference that anyone can provide would be greatly appreciated.

Thank you in advance.

I think you just need to add an event script for event "OnFileUploaded":

Code: Select all

local filepath = "%PathName"
if string.find(filepath,"d:/ftp/test") then
   c_SendMail("test@xxxx.com","a file has been uploaded","%Name uploaded a file '%FileName' ",filepath,"SMTPconfig")
   c_RemoveFileDir(filepath)
end

Thank you so much. You are a lifesaver!!!!

We have a folder structure which looks like..

E:\support\users\<CustomerUsernameHere>\<CustomerUsernameHere>\
E:\support\users\<CustomerUsernameHere>\incoming\

We would like to flush the top Dir out every 60 days for all customers, but leave the bottom Dir untouched. Could this script be modified to achieve such a result?

Presumable we would have to run a loop passing in a different username as a variable to the root clean up dir every-time. It sounds way beyond my knowledge does anyone have anything similar they are willing to share?

Hi!

First, awesome code - really useful!
Secondly, could you modify it so it would delete subdirs aswell?

Thanks! It successfully deletes files from subdirs.
But I was actually more interested in the possibility of deleting the subdirs too.
Is that possible?

General idea is to have a dir where all files and subdirs are kept only for a predetermined time and the automatically deleted by a script.

Or maybe there is another logical solution, rather than a script?

local root_dir = "D:/ftptest"   --physical path for storing temporary uploaded files

      for isdir,filename in c_GetFileDir(nowdir) do
         if isdir == false then
       if filename ~= nil and filename ~= "." and filename ~= ".."  then
           local filepath = nowdir.."/"..filename

Was anyone able to modify this script so that it deletes the subdirectories as well?
