I just discovered three hidden folders on my external HDD, after I'd unchecked the "Hide protected system files" in folder options. As the topic says - one $RECYCLE.BIN, one RECYCLER and one found.000 folder.
So...
1.) In the $RECYCLE.BIN folder, I found två empty recyclers. Yet, right clicking and checking properties they are both 4kb each. Is that the amount of space the recyclers themselves take up, then?
2.) Right clicking and checking properties on the RECYCLER folder, it says it contain 8 files. However, entering the folder, there are only four recyclers with various names but similar sizes. The file names begin with S-1-5-21-4242425(...), and such. However, checking the Disk Cleanup option on the external drive, it said that the recycler consists of 0kb.
3.) In the found.000 folder, there were two sub-folders and one file named file.0000.chk (0kb, yet right clicking/properties said otherwise). I did a quick search on the internets and found out it was safe to delete, and so I did.
So, as a person who uses CCleaner and Recuva to securely delete files and wipe free space from time to time, are these hidden folders and recycle-files of any concern? Should I delete them, or just let them be?
@Gregor -> To add to Hazelnut's reply, let them be. Do you need them? Maybe. More info below:
- Turn off Recycle Bins: Right-click desktop recycle bin/properties/select each you want to turn off. You can keep them if you need, or disable to free space.
- Turn off System Restore: Right-click desktop My Computer/properties/system restore/select drive to disable. Turn off on the drives you need more space on.
* Having multiple drives with enabled system restore & recycle bins can cause slight performance degradation. Additionally, trying to "Restore" an external drive will revert all connected drives. Hence, System Restore is only recommended for the drive with your OS. You can see the problems it has the potential to cause when using on any other drive, since all connected drives will be "Restored" as well. Anytime your restoring your main OS, safe eject disconnect all of your external drives to prevent that they lose data while they are also "Restored".
System Restore info included, because usage on external drives an eat up space & cause fragmentation. Also, it is a waste of space on external drive for the reasons listed above. Recycle Bins may be kept per drive, depending on your choice. I usually leave recycle bins on, but turn off all but the main OS System Restore on mine.
