Win 11 64 bit
I have some archives which have been encrypted, using the encrypt option either in pbs or when interactively creating a zip. When I open these, and look at files, I am asked for passwords, which I know, and then can view items or decrypt the files in the archive (tools>decrypt files).
However, when I use the Actions>Remove Archive Encryption (whether using the same zip or asking to write another), the routine shows progress bar to the end, but then just hangs i.e. “OK” never activates. All process information shows this stalled/hanging.
What can I do to sort this out?
Download this ZIP file: http://dslstats.me.uk/files/dslstats32W-6.5.zip
Everything in the ZIP file is in a directory “dslstats32W-6.5”.
However when I extract using right click “Extract Here” the name of the directory created is “2W-6.5” !
I am running PA 22.00.09 on Windows 11. I have seen the same happen with some other kinds of archive too.
If I compress a folder to a .pa using right click, Compress to folder.pa and use the new Windows 11 menu then the Options, Configuration, Miscellaneous, Use normal relative path setting is always enabled.
But I like this option disabled so I have to use the old style menu in order to get PA to compress a folder in the way I wish.
Just tried using the Modern (Windows 10) Icon set and seeing a few missing icons in both PowerArchiver Burner and PowerArchiver Encryption screens . They are all there in the Minimalistik icon set and the only difference I can see is the former is blue and the latter grey. In version 22.00.9
there were some security issues fixed in 7zip:
As it seems, that PowerArchiver and PACL use the 7zip libraries, could you please update them to the latest version?
I noticed that the version of ZPAQ used is older than the latest released 7.15 https://mattmahoney.net/dc/zpaq.html also there seems to be a newer fork that adds several features https://github.com/fcorbelli/zpaqfranz
It would be useful to implement this latest version (it also maintains the same syntax and behavior as the latest official release if used the -715 flag) and add when opening a zpaq file a choice of the version of the files to show (e.g. as dummy folders represented the various versions present). Since any previous changes are stored with this format, it is possible to extract a snapshot of a certain date/version.
If I open a password-protected zipper file (created with WinRAR but I think that’s irrelevant), open it with PowerArchiver and run “Remove Encryption” on the same file, then reopen it and add a password with “Encrypt Archive,” the resulting archive will be protected with the old ZipCrypto algorithm and not AES as indicated.
(this can be verified, for example, by trying to open the archive files with Windows Explorer, which does not support the AES algorithm)
How to join .tar.gz splitted files?
I have compressed 6 GB folder on our server(LINUX), than splitted using this command,
tar cf myfolder.tar myfolder
split -b 500m myfolder.tar myfolder.tar_
so i got files like this
and so on.
After that i downloaded these files in computer(Windows). Now i want to extract them using Power Archiver, Please tell me how i can do this ?
When i open myfolder.tar.gz_aa in PowerArchiver it is loaded, but when i open 2nd file so i got this error,
PA can not open this file, It does not appear to be a valid archive.
Your help will be appreciated thanks.
You need to “join” the files back into a single file before it can be uncompressed. L/Unix split seperates on bytes and also has a join command - under windows I guess you could try a utility such as hjsplit.
Note: you may also have to rename the files by changing the alpha suffic to numeric
aa -> 01
ab -> 02
ac -> 03 etc.
Still this technique is not working. Please tell me how i can join these files or uncompress them thanks.

Still this technique is not working.
So what did you do and what happened - what error message(s) etc?
I am already assuming that you have enough disk space and that you have NTFS format (for 6GB file).
Thank you, First of all i changed all names .001 , .002 and than used hjsplit and it joined all files, now all are extracting :)

You can also use the copy command from windows command line:
copy /b file1+file2+file3 > whole_file.bin
no extra tools needed :)
