Recently I got a job and I already had my first problems. The fact is that before me a person worked there who for some reason created two folders with files. In my opinion, this is completely unnecessary and I decided to compare the contents, transfer everything that is missing to the first folders, and delete duplicates. It is simply impossible to do this work by looking at and comparing 1 file each; I probably need a month. Advise me a good program to compare files.
