The AppData folder holds the files, settings, and configuration files, pertaining to the apps/programs installed on a system. It is located in the file explorer. The AppData folder further consists of three subfolders: Roaming, LocalLow, and Local. This sub-containers are also hidden. When you install any app on your computer, its files and related data gets stored in one of these folders. The folder in which the data and files are stored is at the discretion of the app itself.

Let us understand the features of each of these folders. The Roaming folder consists of information or data that is related to the user profile and should roam with it. This data is machine independent. LocalLow consists of immovable or stable data. However, this data can be accessed to minor levels.

Whereas the Local type of folder consists of data that is immovable. It is that portion of application data which is particular to the system. This data is large in size and cannot roam with the user profile. Local type of AppData folder is mostly used by apps to store their data.

Fiji is supported on the following systems:

  • Windows XP, Vista, 7, 8 and 10
  • Mac OS X 10.8 'Mountain Lion' or later
  • Linux on amd64 and x86 architectures

However, Fiji (like ImageJ) should run on any system for which a Java 8 runtime is available (Solaris, Raspbian, etc.).


Packages for Debian / Ubuntu

We used to offer Debian packages of Fiji. Unfortunately, for a variety of reasons, we are withdrawing support for these packages until such time as someone is able to maintain them properly, so please switch to using the Linux downloads above instead.

If you are a Debian packaging expert who would like to address this situation, we would love to have your help—please join us in chat or on the forum.

Fiji is distributed as a portable application. That means that you do not have to run an installer; just download, unpack and start it.

  • Many common questions are answered on the FAQ.
  • If you encounter bugs, please see the Getting Help page.

See the source code page for details on obtaining the Fiji source code.
