    Hello Cloudtime, and welcome to Ten Forums. :)

    Here's how in a command prompt for those.


    Code:
    compact /c /s /a /f /q /i /exe:xpress16k %programFiles%
compact /c /s /a /f /q /i /exe:xpress16k %programFiles(x86)%
compact /c /s /a /f /q /i /exe:xpress16k %homeDrive%\MSOCache
compact /c /s /a /f /q /i /exe:xpress16k %homePath%\Documents
compact /c /s /a /f /q /i /exe:xpress16k %windir%\Assembly
compact /c /s /a /f /q /i /exe:xpress16k %windir%\InfusedApps
compact /c /s /a /f /q /i /exe:xpress16k %windir%\Installer
compact /c /s /a /f /q /i /exe:xpress16k %windir%\Panther
compact /c /s /a /f /q /i /exe:xpress16k %windir%\SoftwareDistribution
compact /c /s /a /f /q /i /exe:xpress16k %windir%\System32\Catroot2
compact /c /s /a /f /q /i /exe:xpress16k %windir%\System32\LogFiles
    can I use this compact command after using compactOS:always command?

    ... and my system will still boot?

    Hello, and welcome to Ten Forums.

    If you compact the OS, there's no need to since those would get compacted in the process.

    I want to compress my entire partition C: with xpress16k

    I just have a partition (c:) and i want to compress my entire partition with "xpress16k"

    do you know if this is possible?

    cd "c:"
    compact /c /s /a /i /exe:xpress16k


    PD: I was testing this in usb bootable with windows 10 and give me 100% errors. ... so What Its wrong?....


    compact /c /s /a /i /exe:xpress16k /f "E:\*.*"

    compact /exe:xpress16k /c /s:"C:" /a /f /q /i

    PD: i do not have a partition "D:"
    PD2: 'compact /exe:xpress16k /c /s:"E:" /a /f /q /i' have compres ratio 1:1

    Code:
    C:\WINDOWS\system32> compact /exe:xpress16k /c /s:"E:" /a /f /q /i

    Great news.

    Correct, you would use this below for the C drive.

    compact /exe:xpress16k /c /s:"C:" /a /f /q /i

    thanks for your help sir.
    i have just 3 questions more.

    1- if i compress my c: partition my system will still boot with any problem or error?
    2- using compact in my usb "E:" i have compressing ratio of 1:1 , should not this have a ratio of 3:1?
    3- before use compact compressing in C:, should i change compactos to never? (compactos:never)

    Q1) Not sure, so I would recommend to create a system image to have available to restore if needed. The compact /compactos:always command would be recommended for the Windows 10 OS instead.

    Q2) I can't find anything for specifics about the compression ratio.

    Q3) No need to.

    hello.
    thanks for your help sir.
    my respect for you.

    I'm curious about compact command. If I compress my entire drive "D:" with xpress16k, then all files that I will copy in the future will be compressed too automatically? or Do I will need to convert manually every new file each time that I need to add to my drive such with new installs, backup from my small USB, windows system files, User files, etc.?

    Compressing the whole drive would have anything you save to it also be compressed by default.
