FAQ
Questions before you begin
Does FileNest inspect file contents to sort them?
No. It groups by the original filename extension. Unknown types go into Other.
Will this convert PDFs, images or other formats?
No. It changes only each file's folder inside the ZIP, not its contents.
Can I rename files while organizing them?
Yes. Existing prefix, replace, sort and numbering controls remain available, with conflict checks before download.
