Windows allows to view and manage the contents of a .zip file as if it was a faolder. It would be useful to have the posibility in FFS to open zip files as a folder to compare an synchronize. I work with PLC projects which consist of thousands of files, many of which are very small in size (only tens of bytes). Because of this, it takes a very long time to copy such projects to a pendrive. Im using a rival program which allows me to have a zip file in a pendrive and sync its contents with my HDD. If some change is made. the zip file is processed in de hard drive and finally copied to the pendrive, which is very much faster being a single file.
