Where the sessionStorage and localStorage stored?

Question

Where are sessionStorage and localStorage stored on the client's computer?
Could you tell me the path?

Answer 1

Firefox

Firefox stores localstorage in webappsstore.sqlite file in the profile folder.

Firefox (Windows XP):

C:\Documents and Settings\<Windows login/user name>\Application Data\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite 

Firefox (Windows Vista and above):

C:\Users\<Windows login/user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite 

or:

%APPDATA%\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite 

Firefox on linux:

~/.mozilla/firefox/<profile folder>/webappsstore.sqlite 

Firefox on mac:

~/Library/Application Support/Firefox/Profiles/<profile folder>/webappsstore.sqlite 

or:

~/Library/Mozilla/Firefox/Profiles/<profile folder>/webappsstore.sqlite

Chrome

Chrome stores in separate files inside the Local Storage directory.

Chrome on windows:

%LocalAppData%\Google\Chrome\User Data\Default\Local Storage\ 

Chrome on linux:

~/.config/google-chrome/Default/Local Storage/ 

Chrome on mac:

~/Library/Application Support/Google/Chrome/<Profile>/Local Storage/ 

commonly:

~/Library/Application Support/Google/Chrome/Default/Local Storage/ 

---

Internet explorer:

I am a bit unsure, but think this will do the trick

%userprofile%\AppData\LocalLow\Microsoft\Internet Explorer\DOMStorage 

---

Opera

As said by OammieR:

C:\Users\Administrator\AppData\Roaming\Opera\Opera\sessions\autosave.win 

or as said by Kevin Hakanson:

C:\Users\Administrator\AppData\Local\Opera\Opera\pstorage\

LcalStorage and Session storage are stored as per the browser specific paths (like we have for Cookies)....Also it is kind of limited to the Sandboxed environment of the application. So, only the domain which sets them can read or access it.

Again also remember that only the user has control over expiry of these storage.
