    I wasn't aware that this new line item was added to Disk Cleanup (DC) so I didn't check what it was going to do (Dummy).
    Sure enough I left it checked & ran Disk Cleanup/ delete files & it took longer than my normal DC to run & I found out that all my 'C' drive files & folders were compressed & that the PC took around 2x as long to boot :(

    So I proceeded to decompress the system files (easy) but everything else seemed to take all day.

    SOoo my reason for starting this thread is to warn other members here to be alert to this DC item since it is pre-checked when running DC, unless you want everything compressed by the OS.

    Edit: My W10 is v.1803, build 17134.523

    Simply You have selected from disk option "Compress this drive to save disk space".

    That is how I went through all my 'Other' folders/files to decompress them (unchecked the box) after 1st unchecking the box that had 'read only' also checked on the properties window.

    If no one has the Compress your OS drive in their 2nd box showing up after choosing 'Clean up system files' then maybe its just mine which I think is rather slim IMO.

    Not sure, but possibly play with the following commands (I run #2) to make sure that option never shows up? I've never seen it and do not have it now.

    1. check it: compact /compactos:query
    2. disable it: compact /compactos:never
    3. enable it: compact /compactos:always

    Result reads like so if disabled:
    Code:
    C:\Windows\system32>compact /compactos:query
    The system is not in the Compact state.  It will remain in this state unless an
    administrator changes it.

    I've never blindly checked every box.
    Having said that, including the option to delete the Download folder is incredibly stupid. I store tons of files in my download folder and would be pissed if that folder got deleted. I store downloaded files in the Download folder in Linux too. Linux doesn't ask me if I want to delete stuff from my personal folders, why should Windows? I shouldn't have to restore from backups because Microsoft enjoys deleting s**t.
    Is Microsoft smoking crack? I think they are. My god, what the hell are they thinking? Are you reading this Microsoft? What the hell is wrong with you? Answer me!

    pf100 I never store my downloads on my windows partition or drive same with documents. I always repartition drive or if possible and second drive.
    Even on my laptop added ssd and removed cdrom and put my original laptop sata drive into cdrom type enclosure. So downloads e.c.t stored on sata drive and backed up to an external.

    Yes, but in Windows I redirect the Download folder to wherever it is, so Disk Cleanup would still delete it (I think). I usually always use MBR with 3 primary partitions (System Reserved, C:\, and swap), and an extended partition with logical disks for multiple Linux distros (usually Mint and Kali) so I don't go over the 4 primary partition limit. Since a long time ago I stopped using a separate partition for storing stuff because to me it just wastes too much space, and I haven't lost any data in about 15 years now (fingers crossed). The only time I waste space is unpartitioned space at the end of an SSD to reduce write amplification.

    I would never use Compressed OS.. NEVER, NEVER.. bloat down system.. Also, Uncheck Download (in apart of Disk Cleanup) cuz you will lose all your Download folder!!! Be caution!

    I prefer to not use any of those locations, instead i include my default folders into Library for quick access when using any Open/Save dialog :cool2:. That way i have fast access and Windows isn't involved too much :D.

    Since i create backups (regularly and prior to certain actions) i can get needed files from them via Explorer.

    Sounds like a good idea. Redirects are dangerous in windows 10 since 1809. Shortcuts like in libraries are much safer.
    Next thing you know they'll put a checkbox in disk cleanup to "format all connected hard drives" to free up disk space.

    I got the 'Compress your OS drive' item again Windows 10 x64 this time during Disk Cleanup.
    This is my AV partition after a update I ran DC again, this time the item was not pre checked.

    Hmm. How much free space on what partition size? Didn't get that option so far. My Win partitioms usually have >50% free space :g:.
