Had the same problem...most advice revolved around setting the 'default setting for search results folder is "delete on exit'" to be on. Good advice as far as it went but it was not working.

Found a post elsewhere that noted if Pegasus has crashed out or had some kind of abnormal ending, then even with the setting right, the search results would not (and would never be) deleted.

Cure is to locate files having the  name format LNKxxxxx.PNL   i.e. beginning with the letters LNK and having a PNL extension, then delete them. That deletes the link folder entries, but not the messages themselves.

These files  are in your pmail\mail\<<username>> directory.    Not literally <<username>>  of course...the directory will depend on how you have set up pmail.

Once any locked or orphaned pnl files are gone, normal behaviour is reestablished according to the settings in  the tools...options...incoming mail folder behaviours panel.

Wish I could claim credit for this fix, but it is all the work of someone else whose name and web location I have forgotten in my rush to try out his brilliant solution on my machine.

I would venture though the easiest way to  delete them might be to do a windows search for LNK*.PNL and delete them wherever windows finds them. I doubt that particular filespec would ever be used by anything other than Pegasus.

Using Pegasus 4.52 on Windows 7, I cannot delete subfolders in the Recent search results folder.

When I highlight the subfolder, and click the delete, it deletes each message (well, link) one by one (why?), and when the subfolder is empty, I cannot delete the empty subfolder.

Never had such a problem in the past. Any advice?

Where did you install Pegasus Mail resp. where do you keep your home mailbox directory? See here for issues.

The program is installed in C:\PMAIL

 However, I keep all my mail on another drive called: G:\PRIVATE\MAIL

The question is whether Pegasus Mail can update its configuration files (HIERARCH.PM in this case) in your home mailbox (see Help => About Pegasus Mail => Info for the path): A search folder has a name consisting of hexadecimal characters (a hash). If the file is locked for whatever reason (read-only, access rights, AV scanner etc.) you won't be able to modify your mailbox hierarchy anymore.

In "help", "about Pegasus Main", "info" I have the following line: Home mailbox location: G:\PRIVATE\MAIL
In that location I have the file you mention (HIERARCH.PM).
Checking the properties of this file there is no indication for anything special like read-only etc.
In HIERARCH.PM I can see the different "folders" of "recent search, like, for example, this one:
0,0,"3933f304cc3ce4d5ed295793b4a7a38d","45F77008:Recent search re","Hirooka (26 Oct 10 9:00)"
I am not sure what you mean by: "A search folder has a name consisting of hexadecimal characters (a hash)"
I cannot seem to find any file name that contains, for example, "Hirooka" (one of my recent searches).

Thanks,

I solved the problem thanks to your hint: "If the file is locked for whatever reason".
I run a backup program called SugarSync that constantly backup my files to a server and also synchronize my desktop with my laptop.
As soon as I disabled SugarSync the problem was solved.
I am not sure what exactly is going on and why files are locked, but it's easy enough to disable and enable SugarSync that I don't care.
Thanks so much,
Nachum

Exactly, these filenames aren't named in human readable format, instead the (internal) name looks exactly like 3933f304cc3ce4d5ed295793b4a7a38d which is a hexadecimal hash only consisting of digits and the letters A .. F (some explanations of what hashes are good for can be found on Wikpedia).
