How to find a file corresponding to a segment in a segment

Hello, I have Studio 2015 and I'm currently working on a file that is split into 101 different files. I have installed the TM from the client and created my own internal TM for this project to benefit from fuzzies and repetitions. I'm now on file number 71 and I just noticed that I have made a big mistranslation by making a concordance search in the TMs. I can edit the translation unit directly in the TMs but I think it will correct it only in the TM. How do I know to which file (number 1, 2, etc) this segment belongs to ? Because all I see as infos in the TM window are the date and time this segment was confirmed, but I want to correct the segment in the file too before to deliver it to the client, without opening one by one each file looking for the wrong segment. Thanks,
