These folders are not necessary to be backed up, but if they hold some important data or file, you can consider this. 

Program Data

App Data (mentioned below) and Program Data are similar to one another. It does, however, contain app settings and data for all users in the system rather than storing user-specific files.

Program Data

For example, descriptions of your antivirus program may be included. Many cache files that you don’t have to Backups are here. Because you don’t need to Backup everything, this archive just takes several gigabytes.

You can look up and copy any files for programs for which all the data will be stored, but it is most probably more relevant to the contents of AppData\Roaming.

Remember that only certain versions of the app can be compatible with the settings and data for ProgramData and App Data.

Backup these files can be useful for future reference and comparison, but if these files have been recovered from the backup, you may run into problems.

Here’s the location of ProgramData: C:\ProgramData


The Windows AppData folder holds device-specific settings for applications that have been installed. Three subfolders are found in this folder: Local, LocalLow and Roaming.

Usually, the roaming folder contains information that can pass through Windows computers. Firefox stores the user profiles here, for example. 


Local is, however, meant for only one computer data, including cache files. Local is used. LocalLow is similar but is less important to systems with particular security configurations. 

Nonetheless, this is not necessarily upheld by developers. On a slightly separate tab, Chrome stores user details on a local folder as well as other directories.

It depends on your choice and storage capacity that you can backup AppData. This directory can be copied and pasted into a new system and it will work well, depending on the software, but this will not always be the case.

It’s much better than to copy AppData directly using the backup/synchronization options of the program (such as Chrome Sync). 

When you have space, you can Backup your most-used applications to directories. Yet, because many gigabytes are involved, you can not save the whole folder.

Here’s the location of AppData: C:\Users\[Username]\AppData

Backing up all files and folders is just a waste of time and it would also eat up a lot of space. Therefore, you can consider not backing up a few files and folder that we have mentioned below:

Program Files

C:\Program Files (x86) and C:\Program Files, both of these folder store apps that are installed on your computer.

You can’t just copy and paste them to a different system and you hope they work and you don’t have to backup any of the files. Programmes depend on other data, such as register entries, to work properly. 

Program Files

The exception is when a portable version of an app has been installed. Those are developed as free directories, which need nothing more to function properly with the app.


Backup with current drivers is of no benefit.  If you didn’t know, a driver is a software that enables a Windows hardware device, such as a keyboard, to interface correctly.

Temp Files
