I use TRDCUT utility from WOS:
ftp://ftp.worldofspectrum.org/pub/si...s/TRDCUT11.zip
This utility remove crear sectors at end of TRD images. But some short TRD files are impossible open in UNREAL SPECCY emulator. :-(
For example clear TRD 640kB after conversion have about 3kB, but I can't open it in UNREAL SPECCY.
