Hello,<br />
I found these files last Saturday they start with CA0A.IDX to CTUC.IDX. Then they go from SA00/IDX to STUC.IDX? I have managed to put them all in the Recycle Bin &amp;&nbsp;left them all there. <br />
<br />
I have checked my other programs Office, IE &amp;&nbsp;Outlook Express and everything is working okay.<br />
&nbsp;However I do not know what program has put these files into My Documents folder &amp;&nbsp;therefore I do not know how stop this IDX file extension recurring again?<br />
Thank you, <br />

Programming theory deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features, along with introductory programming concepts like program structure, variable declaration and conditional and looping constructs. Sub-disciplines include the formal semantics of programming languages, type theory, program analysis and transformation, comparative programming language analysis, metaprogramming, domain-specific languages, compiler construction and run-time systems.
