Allavsoft also does not provide any significant control over which media files of the files on offer by youtube servers will be downloaded with just generic text description of a preference but no actual control. It is possible to create a shortcut or batch file to manually make the youtube_dl.exe file in the install folder self update when needed but it's not built in. SOME of these downloaders self update automatically and do not require reinstallation other like allavsoft does not out of the box.

Casedistorted, there are many youtube downloaders out there a lot are completely free or donateware most are based upon the public domain youtube_dl.exe or equivalent set of python scripts the key thing is whether the youtube_dl.exe engine integration has been designed to use the youtube_dl.exe -U self update check and rights management to allow the engine to self update or if that requires the end user to obtain a new complete update of the program dust to obtain a current version of the freely available youtube_dl.exe program.
