The release i get it comes with .NFO (information.nfo). i added .nfo in my template, TC add the information.

however i don't want to upload the .nfo. so i added .nfo in "Delete files with the extension"

TC gives output exactly i wanted. however lets assume there is host error. if i retry the upload TC does not add the nfo information anymore because in first upload try it's already remove the .NFO file. is there anyway TC could store the information from the .nfo and the text file. so even if we retry upload it will fetch the information from it.

another issue is i uploading images from the given folder. i.e i do not use TC to generate screenshot. again if TC retry it cannot upload image since images are removed ("Delete files with the extension")

may be add another feature (not sure if it's hard to add): "Do not upload with the extensions" but use the information if added to template i.e .nfo, .txt.

It's already possible.

You can just enable to "Only upload files which match post type" in "Settings" -> "Process" -> "Upload".

The .nfo (or images) files won't be uploaded at all then (and won't be deleted, so it will be fine when retrying).

It's basically 100% what you want.
