General / Re: Backing up my current configuration of PDFE
« Last post by RTT on August 02, 2026, 03:49:05 AM »
You only need to use the settings backup/restore functionality under the preferences tool. No need to manually backup any folder.

That "questionalable folder" is related to Windows functionality. Google Search AI says it is a registry path segment used inside the Windows Registry's CloudStore hive (under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore). Windows uses this database to cache application display names, publisher info, icon details, and last-launch timestamps for installed programs.

General / Backing up my current configuration of PDFE
« Last post by puckman on August 01, 2026, 08:27:08 PM »
Hi Rui
Thanks for helping me out earlier this month. Restoring my PDF library and my preferred PDFE configuration is still undergoing growing pains.  Moving forward, I am resolved to not only back up my PDF files but the configuration of PDFE as well.
 
Can you verify or comment on my backup strategy below?
1. I have my PDF files that I am working on incrementally on a seperate scratch disk that I will back up incrementally as I change their properties.
2. I found two PDFE folders on my system which I assume contains the configuration files etc. One folder is in  C:\Program Files (x86); another is in C:\Users\[myprofile]\AppData\Roaming.
3. I found a questionalable folder elsewhere on my system drive C:\Users\[myprofile]\AppData\Local\Microsoft\Windows\CloudStore\{94b5dd38-99e0-43c7-bdd5-1c548f3503ff}\windows.data.apps.appmetadata\appmetadatalist\pdf explorer_is1.

Should work, but even this must be done by someone that understand the lang. There is always some technicalities, not specifically grammar or context, that can only be fixed by someone that understand what is written.

Ok it's not perfect, but surely, it's a start till a native speaker decides to do the work.

Like this one: https://github.com/itext/i7js-examples/raw/develop/src/main/resources/xfa/xfa.pdf

I know it's a dated format, but many govt forms, still use it.

Bug reports / Re: PDF-ShellTools Pop-up Error

I had it partially fixed for some time but now I gave it some more work and seems to be totally fixed. I need to test it a little more to be sure.

Will it be fixed in the future?

Yes, it is a bug in the PDF preview handler, when used from the File Explorer. Sometimes the loaded PDF file fails to unload and the out-of-process server, the running PDF-ShellTools.exe I told you to end with the task manager, freezes. But an unresponsive PDF-ShellToosl.exe will not be present when cold starting Windows, so I had to ask.

You may be right - I think it only occurs when I put my PC to sleep (which I do a lot). I still think that is a bug though!

Use the Windows Task Manager to end the task named PDF-ShellTools (32 bit).
Do you get this error from a cold start or sleeping/hibernated session?
