Hi,

for years I've been using the following masks with ClrMAME on macOS:



The first line is for custom icon folders. The asterisk is needed because there is an invisible character at the end of the name that I don't know and can't type. The second line is for folders that reside on servers and contains some housekeeping values for that folder (like window position and size etc.).

I've tried a lot of different formats but I can't get it right on scanner. Would somebody please be so nice and show me how it's done?

unneeded masks are now regular expressions...so the following should fit your needs:

.*(\.DS_Store|Icon.+)$

so it translates to
anything at the beginning (.*)
followed by either '.DS_Store' (\.DS_Store)
or (|)
'Icon. with one extra character' (Icon.+)
which forms the end of the text ($)

The DS Store example is showed as tooltip by the way :-)

Is there any other forum where I can post about scanner? Anything more than a line and spam filter here gets wild.

Private message should work and as mentioned: Logout, maybe clean cookies, login usually works fine....

The above mentioned string still does not catch folder icon files. Maybe Apple changed the name but I can only see "Icon" in terminal. the '*' of ClrMAME seems to catch all the cases (0 or more characters).

Also, of 6 icon files only 4 are reported as unneeded:

Can you send me one of such icon files (e.g. compressed in a zip, so that the full filename is intact).

The "can't determine file size of " and "can't calculate.." messages seems to be correct though since it first tries to read the file to check if it's something valid. Unneeded mask files are filtered out on a later stage...when they were detected as being unneeded.
However I might be able to filter out such masked files from error messages.....I take a note.


Maybe there are more than one printable character at the end...you can try something like this:

.*(\.DS_Store|\\Icon.*)$

The change is that it now expects Icon after a "\" and there can be anything before the end of the line....

Here is an example:

Thanks, I will have a look on it over the weekend....

[Roman]

Hmm....your zip contains two icon files.
One in the MAME folder, named 'Icon_" and one in the _MACOSX folder named "._Icon_" and both are matched by .*(\.DS_Store|Icon.+)$ reg ex.

You can try .*(\.DS_Store|Icon.*)$
The . after Icon refers to any possible character, and the * means none of them , one or more of them....That should actually match anything Icon related....

[carbonide2]

In pre-macOS times, Macintosh files could have a resource fork (it was an inherent part of a file). To ensure compatibility with systems that don't support that, ZIP files contain those _MACOSX folders that contain a "normal" file copy of the resource fork.
I don't know of any app who still uses them but apparently Apple's compression engine still includes them in an archive.

I tried the new exclude mask string, icon files are still flagged. Could we achieve a better result with scanner simply ignoring invisible files (which all of these special files are)?

[Roman]

Hmm..interesting since the regular expression actually should match any possible character in there, no matter how many unprintable ones follow. I will check with some colleagues who maybe able to create me 10 folders with such files....

simply ignoring hidden files..hmm..I will do some tests....

[Roman]

hmm...according to the internet, MacOS creates it as "Icon" followed by a carrige return character. So just for a quick test you may try:

.*(\.DS_Store|Icon\r)$


This won't hide the "can't determine file size" or "can't calculate crc32 of" log message yet....but shouldn't list it as unneeded hopefully....
