Local Shared Object file.

A .sol file is a file created by a Flash .SWF file to store persistent data on a local computer. Flash is a plug-in control that runs in a browser, and is present on most computers. The .sol file allows a Flash presentation to store data (typically settings or user entered data) and retrieve it later when the user views the same Flash file again (i.e. when the user views the same web page again).

These are binary files. Where they are stored depends on the operating system but typically are stored under:

For Windows:
%USERPROFILE%\Application Data\Macromedia\Flash Player\#SharedObjects\
For Linux:
For Mac OS X:
/Users/user-name/Library/Preferences/Macromedia/Flash Player/#SharedObjects/

and under the #SharedObjects folder there will be a folder named using seemingly random letters and in that folders for each website for which .sol files have been generated.

These files may be deleted, but deleting them will mean that the corresponding website's Flash presentation will loose its previously stored information. Depending on what information is stored in the .sol file this may result in information needing to be entered again when the website is next visited.
