I was using Librecad last week to uypdate some drawings and went back to do some more work today but discoverd that all my library except for a few items created of the 25/6/2016 have disappeared. Below is the library list that Librecad showxs anmd that should be there. If you cliclk on any file librecad just opens a blanks drawing. If I use windows file manager to look at the same location (programs files/librecad/resources/library/misc then only the files from 25/6/2016 show up.
Any ideas, the PC hasn't been used for anything since I last used Librecad last week.
No idea. So the LibreCAD opening box shows files that do not exist? Bad drive? Corrupted files? Can you find temporary back-up files, those with # or ~ ? You might search for the lost files with a recovery tool like "PC Inspector File Recovery". Or inspect with a Linux Live system.
Have you had any results meanwhile? Sorry for not being able to help more.
