External Archive(r) (UC2) Handling Problem

but could unpack it without problems both with Alt+F9 and F5.

How can you unpack with F5 if you can't enter the archive?

TC can enter into UC2 (both 7.04a and 7.50a).
So please post a screenshot with error(s).
Also it will be good to share the sample arhive, its path/filename, filenames in archive...
Why it's matter? UC2 doesn't like for example long names, or russian chars, or spaces in path...
added: TC also doesn't support uc2 archives encrypted with ucrypt (they have different extension but may be manually renamed to .uc2)...

DrShark,

UC2 doesn't like for example long names

To the best of my knowledge UC2 can handle long file names.

No. If to pass long name to uc2 (even quoted), it will report

FATAL ERROR 130: Long:\Path\File Name does not exist

1 error has been reported (logged to C:\WINDOWS\UC2ERROR.LOG)

TC passes 8.3 aliases to workaround this limitation...

DrShark,

No.

Well, works fine here.

16. WINDOWS 95 (long filename support)
======================================

In order to remain backward compatible with 16 bit DOS and MS-Windows
software, Microsoft implemented a 'double filename' system in Windows
95. Each file gets 2 names, a short name and a long name.

(Visual) UltraCompressor will preserve both the short and the long
filename of files. UC2 does this completely automatic. No settings or
options are needed to preserve long filenames (or long directory names).

Visual UltraCompressor can show both the long and the short filename.
You can use the F11 key to toggle between viewmodes.

The UC command line needs short filenames (or wildcards like *.*) to
operate. UC will (re)store long filenames, but the only way to directly
view/manipulate long filenames is with Visual UltraCompressor.

And your quote confirms my words:

DrShark,
Well, you may not pass long file names on the command line, but UC2 still knows how to work with files with long names, can store and restore them.

I found out why I couldn't enter .uc2 files.

I had the link in the [Packers] section set up as:
UC2=uc.pif

where uc.pif is placed in c:\windows (default) and pointing to my c:\wc\packers\uc.exe.

That is how I have set up external packers since Windows Commander 2.0 because TC / WC has always been shipped with these .pif files.

For some reason packing and unpacking works ok with the uc.pif file but not entering/listing the file.

I consider it a bug that it doesn't work with the uc.pif file.

If I in stead use this entry in wincmd.ini it works:
UC2=%COMMANDER_PATH%\PACKERS\UC.EXE

But if I use this it once again only works for packing and unpacking, but not listing:
UC2=PACKERS\UC.EXE

This syntax with relative path to TC's program folder works for all other external packers.

That's how TC 7.04a and TC 7.5a calls UC2 when trying to unpack a single file from archive:
its sets the temp (%temp%, %tmp%) as a current dir and then calls uc.exe with filelist as parameter:

C:\Users\Vladislav\AppData\Local\Temp\_tc>uc.exe @C:\Users\VLADIS~1\AppData\Local\Temp\CMD6CD9.tmp

The difference between 7.04a and 7.5 is that 7.5 sets current dir (%tmp% and %temp%) as long name -> UC can't unpack files...

Another difference in filelist CMD6CD9.tmp (it has random name each time):
TC 7.5 stores a path to archive as a long name -> UC can't unpack files...

[petermad]

Haven't had that problem - my %temp% dir is f:\temp (no long names)

I see - so I will try to use short names in the next version. People with this problem should also set the temp var to something like c:\temp .

Thanks. Fixed in TC 7.55pb1.
P.S. The window >>> UC2 (DIR) <<< appearing while reading uc2 content cannot be closed by pressing Esc key. Can it be changed in future version?

[ghisler(Author)]

No, you need to close UC.exe instead.
