Rekordbox is getting old! Needs urgent improvements with the file search/auto relocate

I´ve tried to move my collection from Dropbox to Google Drive and that was a nightmare, it changed all my file names, it didn't work and I had to get back to dropbox, but all my library has missing files, because rekordbox trunked all file names, I am for days now trying to reconstruct my library. Even my backups are not working because all the files names are now only 48 chars length.

This is so upsetting, why the app has to change files names in the first place?? 

I´m about to give up of this mess, this software is looking and feeling old and everytime that a new version comes, nothing changes in this auto relocate function. 

Suggestion, please on auto relocate, put a option to search for the 48 chars version of the file name, as you change it without asking me all my files, at least make it possible to find something, I'm about 2000 missing tracks, that I had to search one by one, cursing everyone that made this mess, the file is there, but with a short name version. This is sooooo annoying!
