RoboTask forum

I need to take files from a number of folders and then run an application on them and then return the files to the original folder.

Is this possible with Robotask?

Unfortunately I don't understand your goal in details...
Do you want to move files into another folders?
You can only copy files, and then remove the copy when process is done.
See Copy/Move File action

I have multiple customers. Each customer as an inbound and an outbound folder. The customer loads files into their inbound folder, I process the files and return to that customers outbound folder.
To do this I have to move the files for all customers files into a common processing folder, process and then return to each customers outbound folder.
It is essential that files are only returned to the correct customers folder.

I thought a process may be to rename the file with a customer code so for example file "first customer.xls " could be renamed to "abcfirst customer.xls
The file is then processed and returned to the outbound folder matching "abc"

Hope that makes sense.
