Question

Why is the autosave backup file useless? The 1.txt file cannot be opened with any PDF utility.

The temp files that are supposedly autosaved every increment we choose under Preference > Save Settings is worthless.  Twice now I have spent hours marking up PDFs of production drawings and lose everything when Acrobat inexplicably crashes.  The temp text file (1.txt) located in C:\Users\ <YourUsername> \AppData \Roaming \Adobe \Acrobat \DC \AutoSave\ cannot be opened with Acrobat, Chrome, Edge or any other PDF utilities.  
Yesterday I spent 2 hours with AI massaging the temp file with Python scripts to repair the file which didn't work and still could not open the "saved" file.  Best I could do was extract my text comments from the otherwise useless file.

Why don't you back up the actual file we are working on in its entirety with a PDF extension that can be opened with the software we are using (e.g. Acrobat)?

    Does it crash if you do a Cmd/Cntl-S on a regular basis instead of depending on autosave?

    Hello @beautiful_Rhapsody88fd,


    I hope you are doing well, and sorry for the trouble you had.


    Acrobat's Autosave file is not a complete backup PDF. Adobe describes it as a temporary file containing changes made since the last autosave, which Acrobat can apply to the original when the app restarts. That’s why 1.txt it won’t open as a PDF in Acrobat or another PDF utility. I’m sorry you lost hours of drawing markups; extracting some comments is not a substitute for recovering the document.


    If you haven’t reopened Acrobat since the crash, restart it and check whether it can apply the autosaved changes. Unfortunately, if Acrobat does not offer the recovery prompt and only the .txt file remains, there is no supported method to convert that file into a complete PDF by itself. Renaming or editing the recovery file may also prevent Acrobat from recognizing it.
