Purging scanned sheets / moving the project files

[ysalmon]

What is a correct way to purge the scanned answer sheets of a survey (in case something goes wrong during recognition, I prefer to throw everything out and re-recognize everything) ?

With earlier version of sdaps, I would delete the entire project and regenerate it.
But with the database now being in sqlite format, I feel tempted to just DELETE FROM sheets; and delete the 1.tif, 2.tif, etc. files.
Is this safe ?

Also, if I want to copy/move the project between computers, is it sufficient to copy those *.tif files and the sqlite file (assuming I do not try to generate answer sheets again, but only recognise scanned sheets) ? The JSON in the surveys table references the project folder : what happens if this does not correspond to the actual folder anymore ?

Yeah, should be safe. There is also a reset command to delete everything, not sure if that currently works though.

Wait, huh? That shouldn't be the case. The survey_dir attribute should not be saved (and is never used).
