Did you transfer the whole folder?

An AUP file is a “small” file with just the “instructions”. The actual audio is in many smaller files (maybe .AU files?.. I don’t exactly remember.

…The new AUP3 format is a “self contained” file with everything.

I did transfer of the whole folder, but my .aup3 files are absolutely not small (from 600 MB to 1.5 GB, depending on the song). The Audacity release is the same (3.5.0) on the same PC (Intel i7, 16GB RAM)
