You can at any time modify or customize this list. We want to mention note here that adding or editing the existing file types can lead to hazardous results if you are not experienced or comfortable with such matters (you should have at least working knowledge of DOS). Please note that a "*" sign means all the part of filename. A "?" denotes a single letter of file name. Please also note that file names in windows are not case sensitive. So let's consider an example.

*.chk on the above means search for all the files whose extension is chk. So it could be File0001.chk, File0002.chk all are valid candidates.

??.chk means to search all the files whose extension is chk but filename must be only two letters long. So FI.CHK is a valid but File0001.chk is invalid as file name is having more than two letters.

C*.Chk means to search for all the files on your hard disk that begins with "C" and have a CHK extension.

*.* : Means all the files on your hard disk irrespective of extension. Be careful.

You cannot mix * and ? in one search like "c*s??.*" . It will be ignored.

You can Add, Edit and Remove the files using the above search rules:

• Add : Add a new search criteria with extension you want to search.

• Edit : Select an exiting search criteria and press the Edit button to
  modify the search extension.

• Remove: You can remove a search criteria by selecting it and
  pressing the remove button. We recommend you to disable it
  by removing the check mark in front of the entry instead.
