How to save a large PCD files as bin files?

[2eon]

(64GB RAM) When dragging and dropping pcd files, there is a delay of several seconds before being displayed on the screen.
After that, click each pcd file while holding down the CTRL key and save it to change it to a bin file, which I think is inefficient.
I just installed this program to convert PCD into bin file, so I don't know how to use it.
I would be grateful if you could tell me how to convert a lot of pcd files into bin files at once.

You should use the command line tool: see https://www.cloudcompare.org/doc/wiki/i ... _line_mode (load the file with '-O', change the output type with '-C_EXPORT_FMT' and save the cloud with '-SAVE_CLOUDS').
