Zip.001 File
Ailene Goldhirsh
Suposse that I have some files that I downloaded from a server and they are zipped with 7zip in multiple parts, the format is something like this myfile.zip.001, myfile.zip.002, ..., myfile.zip.00n. Basically, I need to extract the content of it in the same folder where they are stored.
In general, the HIRO will not create a single zip file larger than 1.5 GB in size because files of that size can often cause problems when you attempt to open them (particularly with older or 32-bit operating systems). However, it is not uncommon for users to request image data in amounts that would exceed this size even with the best compression software available. As a result, the HIRO takes advantage of a zip feature known as "volumes" (also known as a split or spanned archive).
When zipping large amounts of data, the HIRO will use its archiving software to split the large zip file into several volumes. Each volume has the same maximum size; once that size is reached for the first volume file a new volume file is created. This process continues until all of the data has been compressed. For example, assume you have requested a large number of scans and when compressed your data shrinks to 4.75 GB in size. If the HIRO were to provide you with a single 4.75 GB zip file, you might encounter problems when you attempted to open or unzip it (in fact, zip files of this size are impossible to open on 32-bit systems). Splitting the zip file into 1 GB volumes would circumvent this issue, and would look like this:
Although zipping in this manner splits the zip file into smaller files, it is still technically a single zip archive (that is, it is not five individual zip files). To successfully unzip the archive, you will need all the files, and you should only attempt to unzip the first volume (the file ending in .zip.001). Your zip program will automatically recombine the volumes and unzip everything at once. Zipping data in this manner is still considered lossless compression, so all of your data will be intact in its original form.
Unfortunately, the zip utility that is built into Windows cannot unzip split archives. To unzip split archives under Windows, the HIRO recommends the 7-Zip Utility. This free utility is relatively simple to use and can compress and uncompress files in a wide variety of formats. To unzip the example above, you can right-click on the MyImageData.zip.001 file (after you've installed 7-Zip), select the 7-Zip menu, and then choose one of the "extract" options.
Unfortunately, the zip utility that is built into OS X cannot unzip split archives. To unzip split archives under OS X, the HIRO recommends the Keka File Archiver Utility. This free utility is relatively simple to use and can uncompress files in several formats. To unzip the example above, double-click on the MyImageData.zip.001 file after you've installed Keka. The Linux p7zip command line program is also available for OS X. The HIRO is only able to provide limited support for Macs.
To unzip split archives under Linux, the HIRO recommends the p7zip utility. This command line utility is included by default in many flavors of Linux, and is available as an RPM package. To unzip the example above, you would use the following command:
The 'x' option will extract the archive while maintaining full paths. To learn more about the 7za command, the HIRO recommends you review the 7za man page as well as the shared documentation installed by the package. It's quite extensive.
So you need to first concatenate the pieces, then repair the result. cat test.zip.* concatenates all the files called test.zip.* where the wildcard * stands for any sequence of characters; the files are enumerated in lexicographic order, which is the same as numerical order thanks to the leadings zeroes. >test.zip directs the output into the file test.zip.
For a multipart zip coming from a Google Drive download I tried several of the explained methods but didn't work (well). I could finally do it in a simple way from the terminal:unzip filename.zip.001when finished extracting the same with the next part:unzip filename.zip.002and so on ...
If the file says dmg.zip.001, the ".001" part designates the file as part of a set. You can't open the file individually, because you need the rest of the files to complete the archive set. Once you have all the files in the same directory, just extract one of them and the rest will automatically be joined during the extraction. To extract files in Windows I prefer WinRAR (rarlabs.com) but for OSX, I suggest Stuffit Expander ( ).
basically all the *.001 is, is a rar file broken down into pieces(split rar) there's usually a *.rar file, on macs it shows up at the bottom of the list, because its alphabetical order, theres sometimes 50 files separated into certain size archives ... all you need is UnRar ( i think its UnRarX now) its free, fast, and easy to use. I think you might be able to find in the apple download section of the apple website. Just open the Rar file and from there it will automaticcally extract the other *.00# files.
I tried to find out on myself, but after days of trying I decided that I need help. My usecase is to concat splitted zip-files (FilaA.zip.001, 002, 003 - 00x) and I don't really know how many files will be delivered. The files are big and delivery takes time... The last file to be delivered is a notification-file "ready.txt"
To download only the data you don't have to clone the repository fully. You can get the dataset by running the following command in a command line client (e.g. gitbash in Windows or the terminal in Linux or mac osx based operating systems) or a gui based client (e.g. gitGUI or TortoiseGit).
If you use subversion(svn) you can also do it easily by exporting using a GUI based svn client (e.g. Tortoisesvn) or by issuing the following command in a command line client (e.g. sliksvn in Windows or the terminal in Linux or mac osx based operating systems).
In this package, you will find the datset as a Matlab '.mat' file splitted into 3 zip archives, namely RAiD_4Cams.zip.001, RAiD_4Cams.zip.002 and RAiD_4Cams.zip.003. You will also find a 'README.txt' file which has the details about the dataset.
Use this command to re-combine ZIP files that were previously split. Split ZIP files will have a number added to the end of their filenames. For example: Backup Job 1.zip.001, Backup Job 1.zip.002, Backup Job 1.zip.003, etc... Use the Browse... button to select the first file (the one ending in .001). All split parts need to be located in the same folder with the *.001 file. Press Combine to perform the re-combination. The original split parts will not be modified. The re-combined ZIP file will be placed in the same folder as the split parts, and be named without any number extensions, for example: Backup Job 1.zip.
In the event you have split ZIP files, but don't have access to Safe Data Backup, you can re-combine the split parts with a variety of other tools. You are not required to use Safe Data Backup for the re-combination. Any tool that will simply append each part to the prior one will work. For example, you can do this from a command prompt with: copy /b "Backup Job 1.zip.001" + "Backup Job 1.zip.002" "Backup Job 1.zip"
