Windows manifest cache - how do we solve
Is it safe to delete manifest cache?
It acts like a cache and is capped at a certain size, but it's safe to delete. The next time you turn on or off Windows optional features or take updates from Windows Update it'll reappear. The file will be recreated as necessary to help the servicing system do its work.
Instead, I want to show you a nice little trick to completely avoid caching during the development phase of your website, delete 3.0 or 2.0 or whatever you have and even delete the quotation marks but keep the comma and plac if the quotation marks were straight , I want you to put in the micro time and then parentheses as this is a PHP function.
I usually don't like using this option because now literally every single file is re-downloaded every time that can only slow down your development process I just want to disable caching for some Keyselect files in Google Chrome too, which disables caching for all websites and not just for your development website. So when I go to Google or Amazon or Facebook all of these sites load significantly slower because I have this cache option turned off, so I like to leave this turned off and just use our micro-time trick to caching for selected ones Disabling files Cool that will bring this lesson to an end in our next lesson. Creating an interior page template should be a lot of fun.
Keep things going and I'll see you then
Can I delete Windows SXS folder?
If you're trying to free up space, you won't be able to delete the WinSxS folder. However, it's possible to reduce its size deleting those files that are no longer required for the operation of Windows 10, and you can accomplish this task using Command Prompt, Storage sense, and even the legacy Disk Cleanup tool.
I'm sure many of you have at least seen or heard of the app data folder in the window, probably while trying to find a configuration file for a program, perhaps to change an advanced setting, but there are several cryptically named directories in Appdata and sometimes what you are looking for is in the roaming folder sometimes local or even the local lowfolder, but what is the point of these different folders and how is app data related to the program data folder you may have seen elsewhere too? the secret in this article and even if you know what app data is, we're also going to talk about other cool stuff that you probably don't know. If you liked this article, lightly tap the like button and subscribe to future articles first, what is the app? datafolder anyway every windows user has his own and his own username and then app data, it's a hidden folder so you have to h. enable Identified Items to see, which is easy enough to toggle InWindows Explorer at the top under the view ribbon.
Ignoring these subfolders in there for a minute, simply entering app data is used to store additional data that programs use or create that are not part of the original installation files, so basically when installing a program, usually all the files that are required to run , into the directory of program files that most people are familiar with, and then things like configuration files, temporary files, file caches, whatever else is in app data, technically this doesn't always have to be the case, but we'll get to that later. It might be surprising why not simply use the directory with the program files where the program is installed and keep all settings and files in one place where the advantages are of keeping them separate. First, remember that every user on a Windows PC gets their own app data folder when you reinstall a program easier to manage multiple user settings this way because you just inst everything once in program files and then these files, to actually run the program remain the same, but if a user changes their settings, these adjustments can be saved in each user's own app data directory, it is also more secure because users cannot access another user's app data folders with it Nobody can mess anything with your files or settings for this program, the permissions for the user directory are also different and the program files directory App data is in each user's personal directory so that they can access it, but program files are located further up directly in the directory the top one n level, as it contains programs that are intended for all users, but only someone with administrator rights can write to program files, so if settings have been saved there, users might run into permissions problems if they are not administrators a developer might choose , not even a. to use pp-data and just put all user settings in the installation directory if you really wanted to.
I don't know of any advantages, but if the program requires administrator rights or something anyway, I'll also point out that sometimes entire programs can be installed directly into app data, so not just the settings, but the entire program, which can be good if you want to install the program for one user only, but be aware that occasionally app data is the default installation directory for certain programs but usually they either just go into the program files or ask the user which one and a fun fact if you ever ask a program You will be asked whether you want to install for all users or just Methis, whether you want to install in program files and be accessible to all users or your individual app data folder. See that it all comes together now The program is installed and cannot find it in the program files. Don't be surprised if it's in the Appdata folder somewhere, okay, so no we know what the app data directory is for in general, but what about those three subfolders, local local low and roamingwell, all three folders contain basically the same thing File type custom files and preference settings some temporary things, but each folder serves a slightly different purpose, but only sometimes, so let's go local androaming first, as these are the most common, the local folder is the simplest and is called local as it is used for Files is intended to only stay on that particular computer, although it will be easier to understand if you compare it to the Roaming Folder which is intended for files that may be the user in a domain environment and that is the key.
This could probably be an entire article by itself, but simply put, in a Windows domain, many computers are centrally managed, like for a business or school, the organization creates a set of general rules and guidelines that apply to all computers in that domain , and then user accounts are created that can function normally on all computers as part of that domain. These computers are usually also locked and the users do not have administrator rights, so they may not be able to install things, for example, but users can re-access their account on not just one computer but many, like in a school or a company So the purpose of the roaming folder is to store app data that is synced and accessible to users regardless of which computer in the domain they are logged on to. If you get a personally assigned laptop, the files in the roaming folder should in theory also show up when you log in to a desktop or computer lab or whatever the local folder on the other side is just the opposite, these files don't follow you and stay on this computer so the names probably make more sense now, roaming is for files that are running around on different computers and local is only local on this one computer now I know many of you are me guess wait wait, my computer is just mine, it's not part of a work or school domain and on t he admin why i still have a roaming folder that is used with stuff? Well the roaming folder still exists even if you are not part of a domain, it only contains files that would be synced if you were a user on a domain, but if you are not theroaming and local? Folders do exactly the same thing, but that still leaves some questions unanswered when they do the same.Why use programs locally while others are using roamingor, even both at the same time, even if users are not in a domain roaming folder, whether a user is in located in a domain or not, which means that it will work in both scenarios, regardless of what this also ensures that the files have the same file path regardless of the environment, which also means that any documentation about the program and the locations of files is always consistent , for example next question what or who determines what goes into each folder and that is entirely up to the developer, if you are looking for the folder with the settings for a specific program, there is basically no way of knowing whether it is local or roaming without seeing that the developer doesn't care about the settings being synced, and i hn just put in the local folder Use both folders for a program for example Adobe Here there are a lot of program folders in Photoshop Camera Raw probably more in roaming and local I will also point out that sometimes for example large files are specially saved in local, too if it were ideal if they could sync because they would just be slower to sync the domain and other things like this that would definitely be better just to keep them local so basically there is no hard and fast rule for that Folder a program will use so you just have to check both and in fact many programs don't even use app data and can only do settings and so on in the user document directory many article games do this with sav efiles because they know that users are more likely to know that you can see all rights in the documents folder as in the hidden app data, so now on the third ten folder in appdatalocal low this is actually the same as local, but with the so-called low integrity level now Windows integrity levels could probably also be a whole article, although integrity level means the trustworthiness or privilege of an object or program other that are not trustworthy, the even under are low and the installer which is a special one and is beyond the scope of this article anyway, each level can only access things in its own level and lower, so certain programs are run at higher risk than low integrity for more security as it severely restricts which files and folders they can access for example web browsers m If the program or something it is downloading is infected, it is isolated in specially marked folders with low integrity and the Process Explorer program is indeed is used en you see the integrity level of various running programs and you can see most of google chrome for example are running in untrusted and as mentioned yep the local low folder is marked as low integrity so low integrity programs can only write to it which keeps it from the rest of the more trustworthy files, but wait for there to be another folder related to app data which is program data as opposed to app data which is stored in any directory program data is actually stored in the top level of the drive just like program files specifically it is in c programdata when you access it you will see even more settings folders for programs and some that we have already seen in local androaming, I mean seriously, but unfortunately the program data actually serves a purpose they have data for the program and files that are back in are not part of the basic installation, but also not user-specific, but intended for all users, so it makes no sense to put them in just one user directory, so program data is basically for resources that are used by and by the program shared among all users, for example a program could download a dictionary file that can be used regardless of which user is logged in, and it's nothing that an individual user changes, so it goes into the program data or maybe an antivirus is running a scan and stores the results of the login program data so that the results are accessible no matter who is logged in so another fun fact in Windows XP program data used to be the directory of documents and settings of all users application data and nowadays when you try to see all users just get far to the program data and if a program tries to write to all users, which doesn't really exist anymore, it will just write it too and instead redirect to the program data, so that's just backwards compatibility with old programs for xp now still exist one last thing you may be wondering if you are already familiar with windows you may know that the abbreviation for appdata percentapp is data percent, if you type that into the start menu it will take you straight there, but actually it goes to the roaming folder Why? is that fine, supposedly the roaming folder is usually considered the default a developer can choose what to use, but apparently the common practice is to only use roaming unless you have a scope to use local for However, the locallow folder is not linked to the topmost app data folder, because no program should ever write to it and it always has to go to one of these sub-folders anyway.
