Update files in 7Z, TAR, ZIP archives
How to replace and overwrite matching files in archive






Update and replace files inside existing 7Z TAR ZIP archives

The simplest ways to update content of an existing archive with PeaZip are
  • drag & drop new files into open archive: archiving interface will be shown, on confirmation new files will be added to the current archive, and moved to the archive subdirectory being browsed. If files with same names are found inside the archive confirmation will be required before overwriting existing ones.
  • double click to edit file in archive, opening it as preview (files will be extracted for viewing / editing to a temporary work path); if a file is changed PeaZip will ask to update the file in archive with the newer version.
More options (Add, Update, Update only files already in archive, Synchronize archive with disk) are available from archiving creation interface - clicking on "Add" button and selecting an existing archive as output destination.

update files in archive

“Function” dropdown sets the policy to apply when a pre-existing archive with the chosen name is found on the system:
  • New archive 
(default) will force the creation of a new archive, assuring it has unique name

  • Add
Adds the input data to the specified archive, if an archive with same name exists, overwriting any matching file already inside the archive - add option assures input files overwrite archived files, input version will be featured in the final archive regardless they are newer or older than matching files inside the initail archive
  • Update archive

Update existing archive (default when dragging files into an existing archive open in PeaZip file browser) adds the input files and folders to the archive, overwriting matching files in the archive only if input files are newer than archived files - update option assure latest / newer version of files (regardless they are from the input or in the original archive) will be featured in the final archive and never get replaced
  • Freshen files in archive

Update only files already in archive “freshen” the archive content: works as update, but ignoring (not adding) input files not already in the archive, and freshening files already in the existing archive with updated version found on disk
  • Synchronize files in archive

Synchronize archive with disk works as update option, but archived files not featured in the input will be deleted from archive - synchronizing files in archive is the opposite of freshening archive content operation: freshen files in archive excludes files on disk not matching with existing archive content, while synch files in archive excludes archived files not matching with disk content. In both cases excluded files will not be featured in the final archive

What file types can be updated with PeaZip

Please note PeaZip can update (modify) only file formats it is able to write.
This means read-only supported formats cannot be changed, nor updated (but can be converted to a fully supported archive format).
Write-supported file types are: 7Z, FreeArc's ARC / WRC, BZ2, BCM / QUAD / BALZ, GZ, *PAQ family (ZPAQ, LPAQ, PAQ), PEA, TAR, WIM, ZIP, and plain split files .001 (as created by 7-Zip/p7zip, HJSplit, PeaZip, and "split" Unix command).

How to update the content of non-archive files
From Options > Settings > Archive manager tab it is possible to set "Edit non canonical archive types" option in order force adding / updating / removing content in container files with non-archive extension (in example jar, docx, odt, xlsx...) that are, internally, very similar to archives - usually based on zip standard. Please note that this option is off by default and is not recommended for general usage as some container formats employs extra fields that are out of the standard of the archive structure they are based on, and editing those metadata fields is out of the scope for an archive management utility as PeaZip.

How to update encrypted archives

To edit content inside an encrypted archive, the correct password must be provided, clicking locker icon on the right of Output field.
Write-supported encryption standards that can be written from PeaZip, in order to update encrypted archive, are:

freshen archive content

  • 7Z with 7-Zip AES256 encryption
  • ARC with FreeARC AES256, Blowfish, Twofish256 and Serpent256
  • PEA with AES, Twofish, and Serpent 256 bit EAX mode authenticated encryption
  • RAR (if WinRar is installed in the system) with AES128 / RAR4 and AES256 / RAR5
  • ZIP / ZIPX with WinZip AES256 AE, and ZipCrypto for legacy compatibility

Update compressed TAR archives

Please note some formats (BZ, GZ, XZ) only provides single-file compression capability, and usually compress a TAR archive containing actual content: all the above information apply to the TAR archive, which needs to be extracted and handled directly in order to be updated.

synchronize archive content

If solid compression is used, compression process depends on statistical analysis of previously compressed data, which may delay the update process as more data (than the sole input files) needs to be processed and replaced.
