You can select and customize the System Cleaner and Optimizer search for files. By default System Cleaner and Optimizer and optimizer will search for following files:
*.~* ~*.* *.??~ *.--- *._mp : Temporary Files
*.chk : Scandisk lost clusters
*.bak *.old *.syd : Backup files
*.gid : Help file search index.
mscreate.dir : Microsoft Setup temporary files
*.nch *.pch *.ncb *.exp: Visual Studio Temporary files.
*.wri : Readme files
You can at any time modify or customize this list. We want to make 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 letÆs 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 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 Button: Add a new filename with extension you want to search.
Edit Button: Select an exiting filename and press the Edit button to modify the search extension.
Remove: You can remove a search by selecting it and pressing the remove button. We recommend you to disable it by pressing the check box instead of removing it from the list box.
