    Hi,
    1. last alpha version is already 10 days old...are there any good news for new features etc


    2. What about native x64 support ? Are PPMD and multimedia compression the only problems ?
    7z x64 beats FreeARC often when using 256 or bigger dict.

    3. FA can't open encrypted 7z archives.

    4. The "open dialog" in FA shows no rar/zip/7z (must use see all files instead)

    5. new m1-4 and syntax are GREAT

    3. FA can't open encrypted 7z archives.
    a) Just tested: -> problem occures only for 7z archives with encrypted filenames
    b) same for rar

    c) encrypted zip archives created with winrar (Zipcrypto?) or 7zip (Zipcrypto or AES-256) where you cannot encrypt filenames (through WinRar or 7z) cannot be extracted at all with FreeArc

    downloads: 25k (march), 30k (april)

    1. good news that i'm finishing adding new features. please report any problems still remaining so that i will look into this in the next 2 weeks

    2. http://code.google.com/p/freearc/issues/detail?id=146
    http://hackage.haskell.org/trac/ghc/ticket/1884 - add yourself to the first and write small comment at the last

    you can use 7-zip as external compressor. i will add stdio mode for external compressors later so it will not lose efficiency

    3,4. thanks

    just found another small issue:

    If you want to add each marked file/directory to separate archives, FreeArc does not use the specified temp- directory (settings) - nor it uses the window temp file dir. It just uses the directory where the marked files are located. Usually that is not a problem, but if the marked files are on a CD/DVD-ROM ...

    Bulat, did you try to use ghc to compile to C and then mingw (or whatever) to get x64 binaries?

    new version:
    • Installer: "associate with other archives" checkbox
    • GUI: open .tar.gz-like archives in one step
    • GUI: save passwords entered due the session (well, only passwords used to open archive are currently saved)
    • show description of operation in window title ("Extracting archive xxx" and so on)
    • 7z.dll: remove files extracted with error, unless -kb is specified
    • cw command: now supports zip/arj/... comments
    • GUI: updated speeds on Compression tab according to new m/t methods
    • GUI: 7z.dll: show "Skipping ..." on files being skipped
    • GUI: fixed: update Totals label after jumping to another archive/directory
    • mmdet: fixed bug in entropy calculation

    4. The "open dialog" in FA shows no rar/zip/7z (must use see all files instead)
    there is "All files" among the filters. ideally, it should save last filter used. most users probably still use FreeArc for .arc archives. may be, it should set default filter based on "Associate with non-FreeArc archives" option

    moreover, i think about fields in Settings dialog that will allow user to specify extensions which should be cosidered as archives. with 7z.dll, any file may become an "archive"

    Bulat, did you try to use ghc to compile to C and then mingw (or whatever) to get x64 binaries?
    of course, that's impossible

    Thats sounds really good.. this should make it easier to wait for x64 FA

    i think about fields in Settings dialog that will allow user to specify extensions which should be cosidered as archives
    I think this would be a nice feature

    last but not least.. new version is here

    Hello everyone,

    is there some special reason you stay with 7z.dll-version 9.07 in your distributed packages? At least in portable version it is this way.

    Best regards!

    i can't confirm any of these problems. please try with new alpha, may be it disappeared on its own


    you stay with 7z.dll-version 9.07
    because new version may have new problems. it may be incompatible with my code, has new bugs and so on. i've updated to 9.13, next alpha will include it

    Hm.. this problem still exists. I tested it with 7z archives created by new beta (9.xx) and the old stable version... if the filenames are encrypted FA can't open them.If filenames are not encrypted they can be opened, but not extracted!

    Alpha from May 4 2010 is still unable to open RAR with encrypted filenames, only asks for password on the beginning ("not an archive or corrupted archive; no archive identification found").

    One more thing: even though opening tar.gz from within FA's own filemanager gets right to the data (thanks!), opening the same archive from Window's Explorer does only open the outer .gz layer.

    EDIT: Right-click context menu only offers to decompress the gz, but not the inner tar, too.

    Hi Bulat. I'm not sure if any has mentioned this before: Can you add drag support for FreeARC? Drag into FreeARC window for compression or drag out for decompression. It is very useful I think.

    Seems to be the same problem that's discussed in 7-zip's forum as "atomic operation for tar.gz".

    i tested FA on encrypted archives of various kinds and haven't found any problems. please test with archives i attached. and please attach archives that don't work for you.

    may be it's 7z.dll version problem?

    Can you add drag support for FreeARC

    What is the password?

    EDIT: Password is "1".

    EDIT2: Attached is archive with RAR and 7z encrypted archives, password is "keloy4", FA can't open it. If I pack the same file in RAR with password "1", FA has no problems.

    Opening archives.zip with FA gives these results for me (double-clicked inside FA):
    - encrypted.zip gives 4 files (opening in 7-Zip) => 4.cmd 5.cmd 6.cmd 7.cmd. If i try to open one, a password is asked for
    - encrypted.rar asks for password *before* opening in 7-Zip
    - encrypted.arc tries to open inside FA and asks for password
    - encrypted.7z asks for password before opening in 7-Zip
    - encrypted-p.rar is opened in 7-Zip and tect.cmd (<- russian?) is shown. If I want to open the file a password is asked for
    - encrypted-p.arc opens a new instance of FA and shows mc-test.cmd. When I double-click it a password is asked for and when I click "Cancel" an error is thrown
    - encrypted-p.7z opens in 7-Zip and when I want to edit the loop.cmd inside it askes for a password
    Since I have no password, I can't give one

    If I try these steps from an unpacked archives.zip (all archives in a folder, opend in FA via context-menu):
    - encrypted-p.rar When I double-click the file inside a password is asked for since I have none I click "Cancel" -> FA hangs
    - encrypted-p.arc is double-clicked and opend in FA. Double-clicking on mc.tes.cmd gives password-dialog. Clicking "Cancel" gives an error: "ArcExtract.hs:111:47-114: Non-exhaustive patterns in lambda" and then "User error".
    - encrypted-p.7z same as encrypted-p.rar
    - encrypted.7z asks for password (none given) => Error: "Prelude.undefined"
    - encrypted.rar behaves the same
    - encrypted.zip same as encrypted-p.rar
    - encrypted.arc (double-clicked) asks for password (none is given) -> dialog is shown "Vorgang durch den Nutzer abgebrochen" and nothing more happens
    Most recent FA (May, 4th 2010), 7-Zip 9.13 beta, Win XP SP3

    Best regards!

    Yep, I read it *after* I tested the archives
    Via context-menu:
    - encrypted-p.rar works
    - encrypted.7z works (asks two times for password)
    - encryted.rar works
    - encrypted-p.arc (double-clicked and context-menu) works
    - encrypted.zip works
    - encrypted-p.7z works
    - encrypted.arc (double-clicked and context-menu) asks two times and works
    Btw => the errors described in my last posting above are there without doubt.

    Best regards!

    @Bulat: seems you're right: all of your attached encrypted test archives work fine with latest FreeArc alpha.

    in my test, which failed, I used 7z v9.13 beta x64 and WinRar 3.93 x64 for compression/ encryption

    the problem was utf16<->utf32 encoded strings impedance. on lsb systems, single-char password can't reveal this bug

    Hello everyone,

    can anyone confirm these:
    - encrypted-p.rar When I double-click the file inside a password is asked for since I have none I click "Cancel" -> FA hangs
    - encrypted-p.arc is double-clicked and opend in FA. Double-clicking on mc.tes.cmd gives password-dialog. Clicking "Cancel" gives an error: "ArcExtract.hs:111:47-114: Non-exhaustive patterns in lambda" and then "User error".
    - encrypted-p.7z same as encrypted-p.rar
    - encrypted.7z asks for password (none given) => Error: "Prelude.undefined"
