Quick Save path keeps resetting

I've been using HS for years, but only the past few months have I had this issue.  I keep losing the path in "Capture Settings > Quick Save" so that captures are not being saved in the folder I specified.  This seems to happen at random as I've not yet discovered a cause.
 
The only possible thing I can think of is IOBit Advanced SystemCare.  I'm wondering if there's a chance HS keeps this setting saved in a place where ASC is doing its cleaning operations and is getting lost that way.  Although, I don't seem to be losing any other settings, so why only this one?
 
Where is this setting saved so I can make sure it's not lost?  Is it a registry key?

Thanks for the quick reply.
 
Hmmmm well I do keep HS open all of the time, but I've exited/launched it several times as well.  It's possible that something is happening during exit or Windows shutdown that is causing that particular entry to become corrupted.
 
If it happens again I'll check the registry entry to see what it changes to.
 
When this happened earlier today, after I posted here, I searched my PC for my recent snap and found that it didn't actually save anywhere, so now it's not just an issue of them not saving in the right place, but not saving at all.
 
Thanks again!

I really don't know and don't understand what happens there. Could be that the system registry is somehow corrupt, or the file system is damaged, or other erroneous conditions exist on this device. Or maybe the problem is using "My Documents" folder, which under newer versions of Window is no longer a folder, but a "junction" pointing to the actual folder, usually at C:\users\user_name\Documents. I see strange things happen on my Windows 10 computer when I try to enter "My Documents" under my user name. It is not shown by Windows File Explorer, by under the Command Prompt I can use
 
cd "My Documents"
 
and the command prompt seems to enter it, but when I try to open an explorer window there, I get message "C:\Users\greg\My Documents" is not accessible. A dir command there shows only "File Not Found". Simply avoid the aliases or "junctions" like "My Documents", "My Pictures" etc. which date to Windows XP and earlier era, and use real folder names.

I really have no more suggestions beyond what I have already written in this thread. Just checked on my machine, the FileName value in the registry that I have set some time last week (and rebooted the computer many times since then, I shut it down nightly and start over in the morning), is still present. If you are still using "My Documents" folder, please stop using it, and instead use simply Documents

I found what so far appears to be a working "workaround".
 
If I launch Hypersnap using the following arguments...
 
HprSnap8.exe -ra -QuickSave,0,1,1 -save:png C:\Hypersnaps\snap00.png
 
This will set the quicksave options each time HS is launched even if they got screwed up some time prior.  I still never figured out why they're getting screwed up in the first place, but as long as I use this each time I launch HS (I'm using an AHK script to launch it) then that should circumvent the problem.
