If I remember correctly it, or some variants at least, do not encrypt entire files if file is above xMB file size but few 256 KB areas only. So then depending on file type partial file repair may be a last option.

What he says ^^^ is correct.

Thanks Arch Stanton ,Thanks for replying
You are right I have repaired few SQL files though repaired files do not directly open in clients software , developer was successful to extract useful data and reconstruct database again.
Unfortunately in this case this particular variant is super strong and clients entire network is affected (having nearly 500GB office files) so cannot work on thousands of files .Besides doc & pdf files are having weak structure , I haven't been successful to repair any file of these 2 types.
