Error: is not an AxCrypt file.

[P.Petrov]

Hello, i receiving error when i try to open txt file with passwords, i use the same file long time and today when i try to open it there was error:

” is not an AxCrypt file.

The file was always encrypted with axcrypt – i dont know why now stops working. There are all my passwords and i not have another backup.

The app version is: 2.1.1399.0, but the file is encrypted with version 1, there was no problems till today.
The algorithm is: AES-128-V1

I tried to open other files which are encrypted in the same was – they work normally

Hello!

Can you send a screen shot showing Windows Explorer and all the normal columns for the file (modified, type, size) in “Details” view pleaase?

If you do not want to publish the name of the file or a screen shot here, either edit it or send an email to svante dott seleborg att axcrypt dott net .

I send you email with the screenshots

[P.Petrov]

The problem happens after restart of the computer for Windows Update, it was not force restart – everything was closed before that.

btw: i found backup file which was several days old and its OK, i will make more regular backups of the files to ensure in case the there is the same problem again.

[SvanteSpectator]

Backups are always the right thing, regardless of encryption or not.

It sounds very unlikely that the Windows restart had anything to do with it, as described by you.

In the private email I sent you I asked about the exact sequence of events, and also what interaction if any you’ve had with AxCrypt 1.7 or earlier with this particular file.
