building back chk files windows?

Question

at the moment there seems to be a load of .chk files on it...the files range from 32k (so I guess not much multimedia stuff on them) to about 4 gig.
Windows (of course) cant see these files via explorer - but i noticed when i plugged the drive into an ubuntu box i see all the check files. Oddly enough if i run acronis disk director via windows i can see the files - but the program cannot seem to build them together.
so next step was to copy the files to a usb drive and plug that into a ubuntu laptop. when i play the check files through a player such as vlc media player (on ubuntu) - i get SOME video. which is obviously a lot better than nothing...
..but now at the moment i've got around 10,000 of these check files - and i figure at least 1,000 are check files for video.
but the chk files have numbers for filenames e.g. 3454.chk. There doesn't seem to be a way of intentifyling what file they were originally.
so my questions are

1) is there a way without playing the checkfile to see what file it was originally.
2) and i think this is the key one...once i get a group of files that make up a video - how do i link them. Im NOT sure the pieces are sequentia so the numbering system may not workl (do correct me if im wrong)- so i've got this feeling if i simply change them to .avi files and use an avi joiner this will NOT work...

i've tried using the various 'chk file' conversion programs avaiable on the net - as well as using acronis disk director - which was of absolutely no use.

any suggestions would be much appreciated. this is my entire multimedia collection - so i'd be grateful for any pointers. i think i will eventually reformat the drive to ntfs - but would like to get as much usable information from the disk as possible.beforehand.

In your Ubuntu box, open a terminal.  Go into this directory and for each file, type "file file0001.chk".  This will tell you what type of file it is.  Then you can do "mv file0001.chk file0001.avi" (for example).  You could even move them across to a portable drive, e.g. "mv file0001.chk /path/to/portable/file0001.avi".  (Of course, after renaming the extension you can view them to find out what they are and rename them back to the original name as well, of course)

Hope that helps!
