Can we delete files located in CORE_DAT/logger/<logger_id> or CORE_DATA/data/filler using unix rm command ?

1. It is highly recommanded to use the archiver to do it
The risks to delete files manually are :
- to delete a file that is being processed
- to make the Message Log fail (the "edit" button will not siplay the data)
- to make server tasks unable to restart (because some index files won't exist anymore)

2. If, for some reason, the customer cannot use the archiver (or if he does not have time to create and test the archiver), the advice is to delete the following files :
- CORE_DATA/logger/<logger_id>/ixxxxxx
- CORE_DATA/filer/ixxxxxx

It will not prevent Integrator to run, but it will just prevent the Message to display processed entries ("edit" button)

BUT don't delete the other files (axxxxxx are active files, dir1, dir2, *.idx, lock, xf_* etc...), otherwise, you will loose data, or Integrator won't be able to restart
