Arl files

Arl is an old American file type mostly used by hackers to get around Windows scanning their files... most the time you can simply open them with notepad in order to read the info

that drive is a backup storage so its the 00 files you prob really want and they are another 'discontinued software' i.e, you change the 00 to Obj or Fbx [whatever you think the file may actually be] in order to open it

none of this has anything to do with Adobe but my advice is to stay away from old hacker sites mate... not a safe place for noobs to hang out
