As a result of the recent postings on clt, concerning a tcl/tk only file finder for windows, the following is a crude, slow, but working script (which really has a lot of room for improvement), however, it does work;

The one thing that you can do with this is to build lists of files with varying filenames across different drives. You will have to script a way to export the list for yourself... ;^)


In order to properly search an NTFS system (where a user might not have permissions on all directories, change the following: In
 proc ::fileutil::find {{basedir .} {filtercmd {}}} {

# assorted commands removed
     if {![catch [cd $basedir]]} {

# assorted commands removed
     cd $oldwd
     return $files

LES Of course it is slow. You'll be a lot better off building and saving a file name list that can be searched later on instead of scanning disks in every search. In my system, whenever PowerPro detects lack of mouse and keyboard activity for 30 minutes, it launches my Tcl script to scan all drives and update the list. When I run a search, I'm only searching a flat text-based list, so it is fast. It would be even faster with an SQLite database (although the first query within a certain time span always is slow).

And I almost forgot to add an interesting bit: my method follows exactly the same model of the updatedb/slocate pair of Unix tools, but in my experience, Tcl always seems to scan and index my disks considerably faster than updatedb.

Another way of recursively file walking is shown on page Matthias Hoffmann - Tcl-Code-Snippets.
