Application Data Storage
Applications often require a dedicated location for storing the application data, such user settings, profiles and documents.
The choice of the storage location can vary wildly between different purposes, applications and operating system, but generally speaking they follow one of the two common conventions.
- Portable versions – Portable applications usually do not require any system specific installation or uninstallation routines, instead, they come in a form or an archive which you can unpack anywhere you like. All (or almost all) application data is stored in the same directory as the application executable file. This makes the application folder self-contained and portable.
- Installer versions – The application executable is normally installed in a system protected location (e.g. "C:\Program Files"), while the application data is stored in a separate user-accessible location dedicated by the operating system, such as the user profile directory (e.g. "C:\Users\User").
Where is my data
If you are using the installer version, your application data should be stored in the user profile directory.
Type the following path into the address bar of File Explorer:
There, you should see one or more sub-folders, one per installed application.
In a standard Windows installation, for a username "UserName" and an application name "AppName", the fully resolved path should look like this:
UAC and VirtualStore
Microsoft has introduced a concept of virtual storage, as a part of the User Account Control (UAC) system, for backward compatibly with legacy applications which attempt to save data in protected locations, such as "C:\Program Files". This feature was introduced in Windows Vista and is also present in later versions of Windows. For more information, see New UAC Technologies for Windows Vista.
This feature affects some older versions of den4b products, which always store user settings in the application executable folder. If the application was installed in a protected location, the actual saved content would be redirected to the so called VirtualStore location, usually without the application ever knowing the real path.
Type the following path into the address bar of File Explorer to access the root VirtualStore location:
Example of VirtualStore path
For example, if a legacy application was installed in:
And the application attempted to save a file in:
The actual file would be transparently saved in:
Assuming a standard Windows installation with a username "UserName".
