    Hello,I have realy problem.
    My file have ctx format.File is on a flash drive.
    What happened …
    I always open this file on Windows(10) and Linux machines.And all was well.Cherry tree version(win10-0.37.6|linux-0.37.4)
    But yesterday Windows somehow rewrote my file to 0. File Size changed to 0 bytes.
    The Windows can managed to restore the master file ctx.But the rest of the files with the prefix ~ ,looks like this (ctx ~, ctx ~~, ctx ~~~) .were erased to 0.
    What led to the fact that the database password is no longer suitable, at the same time it is of course true.
    Help! Who knows what can be done! I would be grateful for any help,file is very important…

    If you can restore the .ctx, forget about the .ctx~ that are just past versions… I would like to understand what could cause this, I’ve never been able to figure out 🙁

    I thought that ctx~ file can break the access to the file,because password does not work.It’s my mistake.I understand it.
    But why then the password on the file is no longer suitable?
    And what can be done?

    Try to open the .ctx file directly with 7zip and report here

    Why a password longer fit?
    What can be the reason for this?

    You open the .ctx file with 7zip. The .ctx file is merely a 7zip archive, you can also rename it to .7z, when you open it he asks for the password and the extraction gives you a .ctb
    If the password doesn’t work anymore it is likely that the archive was corrupted.

    If the password doesn’t work anymore it is likely that the archive was corrupted.

    This scares me.
    In terms of the possibility of archive corruption, is it safer to switch to .ctb or .ctd?

    Sure, while unfortunately few users had lost data with a password protected document on windows OS, this never happened with a non password protected document or on linux.
    The password protected documents on windows rely on 7za.exe from 7zip.
    Having said so, I’m personally using password protected documents on both linux and windows and never experienced this data loss issue

    I don’t really need the password protection.
    So I switched to .ctb for now.

    Is there any practival difference between the SQL and the XML formats?

    The xml always reads and writes everything while sql reads and writes only what required so it is better for larger documents
