Anti-r-c_ST is a new patch that applied to JDownloader (the famous downloader for file hosting sites) allows to easily download files from providers where many times the automatic captcha code recognition fails (for example Hotfile, FileServe, FileSonic…) avoiding to manually insert them.
Authors describes that the patch has been improved of the previous version, about 30% better. Many times you need various attempts after the code is successfully recognized, but if it happens that maximum failed attempts exceed then you must wait for IP renewal.
The patch is for Windows O.S. and once downloaded you just need to overwrite files/folders where JDownloader is installed.
