How To Unzip A.z File In Unix


Some files may have file extensions like 7Z.Z00, .7Z.Z01, 7Z.Z02, etc. These are just pieces of a whole archive file (a 7Z file in this example) that have nothing to do with the UNIX Compressed file format. You can join these types of files back together using various file zip/unzip programs.

HP-UX does not support Joliet at all: if a disk has been prepared with Joliet standard long filenames, HP-UX will fall back to plain ISO-9660 style filenames: 8+3 US-ASCII characters, all upper case, and a file version number (usually ";1") appended to each filename.


When preparing a CD for HP-UX, you should instead tell your CD burning program to use a standard called "Rock Ridge": in addition to long filenames, it provides support for Unix-style file ownerships and permissions, symbolic links and other POSIX-compliant filesystem features. Unfortunately, Windows cannot use the Rock Ridge extension information, but it won't prevent CD burning programs from including it.


In general, it is possible to use both Joliet and Rock Ridge extensions on the same CD: that way, long filenames would be readable on both Windows and HP-UX systems. Unfortunately, most Windows CD burning programs don't do this by default, and some cannot do it at all.


A Z file is compressed UNIX file used to archive files and save space. Like many UNIX compression formats, a Z file can only contain one file. However it can be used to deliver a group of files as long as they have been archived by a multi-file archive tool first. On a UNIX system, this file can be handled using the Compress or Decompress commands. On a Windows system, you can open Z files using WinZip.


I'm trying to uncompress a *.Z file using Python. I downloaded it via FTP (binary mode). The file successfully uncompresses with 7zip (whose "info" on the file says it's of type "Z"). The original file can be found at


Python does not have the equivalent of Unix uncompress available in a module, which is what you'd need to decompress a .Z file. You would either need to a) shell out to the Unix compress command, b) shell out to gzip, c) shell out to 7-zip (both gzip and 7-zip have the ability to decompress .Z files), d) modify the original uncompress code in C and link that to Python (the code is available online), or e) write your own LZW decompressor in native Python.


If you cannot open the Z file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports Z among those that are installed on your device.


The inability to open and operate the Z file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Unix Compressed Archive Format file. Below is a list of possible problems.


If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the Z file should operate with your programs without any problem. If the problem with the Z file has not been solved, it may be due to the fact that in this case there is also another rare problem with the Z file. In this case, the only you can do is to ask for assistance of a professional staff.


If you want to associate a file with a new program (e.g. my-file.Z) you have two ways to do it. The first and the easiest one is to right-click on the selected Z file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the Z file extension to the corresponding software in the Windows Registry.


Many files contain only simple text data. It is possible that while opening unknown files (e.g. Z) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.


Download all the versions of a blob from Azure Storage to local directory. Ensure that source is a valid blob, destination is a local folder and versionidsFile which takes in a path to the file where each version is written on a separate line. All the specified versions will get downloaded in the destination folder specified.


--backup Activates Windows' SeBackupPrivilege for uploads, or SeRestorePrivilege for downloads, to allow AzCopy to see read all files, regardless of their file system permissions, and to restore all permissions. Requires that the account running AzCopy already has these permissions (for example, has Administrator rights or is a member of the 'Backup Operators' group). This flag activates privileges that the account already has


--blob-type (string) Defines the type of blob at the destination. This is used for uploading blobs and when copying between accounts (default 'Detect'). Valid values include 'Detect', 'BlockBlob', 'PageBlob', and 'AppendBlob'. When copying between accounts, a value of 'Detect' causes AzCopy to use the type of source blob to determine the type of the destination blob. When uploading a file, 'Detect' determines if the file is a VHD or a VHDX file based on the file extension. If the file is either a VHD or VHDX file, AzCopy treats the file as a page blob. (default "Detect")


--block-size-mb (float) Use this block size (specified in MiB) when uploading to Azure Storage, and downloading from Azure Storage. The default value is automatically calculated based on file size. Decimal fractions are allowed (For example: 0.25).


--decompress Automatically decompress files when downloading, if their content-encoding indicates that they're compressed. The supported content-encoding values are 'gzip' and 'deflate'. File extensions of '.gz'/'.gzip' or '.zz' aren't necessary, but will be removed if present.


--exclude-path (string) Exclude these paths when copying. This option doesn't support wildcard characters (*). Checks relative path prefix(For example: myFolder;myFolder/subDirName/file.pdf). When used in combination with account traversal, paths don't include the container name.


--include-after (string) Include only those files modified on or after the given date/time. The value should be in ISO8601 format. If no timezone is specified, the value is assumed to be in the local timezone of the machine running AzCopy. E.g., 2020-08-19T15:04:00Z for a UTC time, or 2020-08-19 for midnight (00:00) in the local timezone. As of AzCopy 10.5, this flag applies only to files, not folders, so folder properties won't be copied when using this flag with --preserve-smb-info or --preserve-smb-permissions.


--include-before (string) Include only those files modified before or on the given date/time. The value should be in ISO8601 format. If no timezone is specified, the value is assumed to be in the local timezone of the machine running AzCopy. for example, 2020-08-19T15:04:00Z for a UTC time, or 2020-08-19 for midnight (00:00) in the local timezone. As of AzCopy 10.7, this flag applies only to files, not folders, so folder properties won't be copied when using this flag with --preserve-smb-info or --preserve-smb-permissions.


--list-of-versions (string) Specifies a file where each version ID is listed on a separate line. Ensure that the source must point to a single blob and all the version IDs specified in the file using this flag must belong to the source blob only. AzCopy will download the specified versions in the destination folder provided.


--log-level (string) Define the log verbosity for the log file, available levels: INFO(all requests/responses), WARNING(slow responses), ERROR(only failed requests), and NONE(no output logs). (default 'INFO'). (default "INFO")


--overwrite (string) Overwrite the conflicting files and blobs at the destination if this flag is set to true. (default 'true') Possible values include 'true', 'false', 'prompt', and 'ifSourceNewer'. For destinations that support folders, conflicting folder-level properties will be overwritten this flag is 'true' or if a positive response is provided to the prompt. (default "true")


--preserve-permissions False by default. Preserves ACLs between aware resources (Windows and Azure Files, or Azure Data Lake Storage Gen2 to Azure Data Lake Storage Gen2). For Hierarchical Namespace accounts, you'll need a container SAS or OAuth token with Modify Ownership and Modify Permissions permissions. For downloads, you'll also need the --backup flag to restore permissions where the new Owner won't be the user running AzCopy. This flag applies to both files and folders, unless a file-only filter is specified (for example, include-pattern).


--preserve-smb-info For SMB-aware locations, flag will be set to true by default. Preserves SMB property info (last write time, creation time, attribute bits) between SMB-aware resources (Windows and Azure Files). Only the attribute bits supported by Azure Files will be transferred; any others will be ignored. This flag applies to both files and folders, unless a file-only filter is specified (for example, include-pattern). The info transferred for folders is the same as that for files, except for Last Write Time which is never preserved for folders. (default true)


--s2s-detect-source-changed Detect if the source file/blob changes while it is being read. (This parameter only applies to service-to-service copies, because the corresponding check is permanently enabled for uploads and downloads.)


--s2s-preserve-properties Preserve full properties during service to service copy. For AWS S3 and Azure File non-single file source, the list operation doesn't return full properties of objects and files. Topreserve full properties, AzCopy needs to send one more request per object or file. (default true)


The .z files, however, can only contain one file. Therefore users will archive the files using e.g., TAR first and then compress the .tar archive with the "compress" command, resulting in a .taz or .tar.z file.
