What is a .036 file?

The file named .036 signifies volume 36 among numbered volumes which are usually found with filenames like .001, .002, .003 and similar. File name alone does not provide enough information about original files type. These contents of these segments belong to a variety of ZIP or other formats (RAR, 7z, Disk image format, movie file, dump database, Install files) and more and more large file which has been fragmented into small volumes.

File splitter applications or older backup schemes with removable disk have created such numbered volumes. Such segmented files usually can be met on big file downloads, segmented files archives, recovery kits, CD-DVD sets that were created using outdated backup schemes of FAT formatted partitions and also copying from FAT-formatted disks to the folders.

To detect volume sets users have to look at the start volume like .001 because in .036 there is often the middle of compressed or arbitrary data.

The filename extensions like archive.zip.036 or archive.7z.036 or file.rar.036 indicate container's original format, however, extension .036 specifies the volume 36. Separate file .036 usually is useless, because .036 is lacking preceding byte ranges along with the most headers which are located in the starting volume. You should not rename .036 in .rar, .zip or in any other file container without explicit instructions from the split set description.

More details about opening .036 files

There exist such applications like 7-zip, PeaZip, Winrar and WinZip, which can handle files that have numbered parts extension such as .001/.027 on windows as well as total commander and splitting software Gsplit /Hjsplit.

To unpack such multivolume archive on mac OS X it can be opened by using Keka, The Unarchiver, PEA ZIP, WINZIP MAC application or the cat command via terminal. On Linux OS one could use 7-zip/p7zip, Pea zip ,hjsplit in those cases where this program exists or using the cat command as well.

For example on Android devices WinRAR for Android,Total commander application should be used if there are enough split files, whereas on iOS devices WinZIP allows users only unpack some types of multivolume archives and joining in arbitrary way does not possible, unlike to desktop environment.

In case it is necessary open a .036 split file by double-click action on desktop computer, first of all user needs to gather all the numbered parts (.0xx) into one folder with base name of files should exactly be coincided, afterwards user should open the .001 file or join files using splitter program functionality. In second case the user should run all the parts consecutively and use web interface will not be convenient for such task execution as they are huge and could contain private data.

Technical details

A common size for a file in the .036 format tends to be a user-chosen split size. Unlike some other extensions there is no universal sequence of magic numbers that would describe such a file in a particular manner and the lack of the header means that this segment starts right where the part 36 starts and so the offset tends to approximately be 35 times that which has been used while splitting parts out of the original stream and the contents tend to consist of either compressed data blocks or the actual file body rather than its file body, the result being that its MIME type is going to be application/octet-stream in the majority of cases.

The segments which are being created using a regular splitter have the same fixed size apart from maybe the last fragment such as 1.44 MB, 100 MB, 650 MB, 700 MB, 1 GB, or 4 GB. Though there are tools that store metadata about multi-volume archives into its header, not all splitters tend to keep any such header information. Therefore, there is absolutely no metadata inside the file other than maybe those that had previously been kept within the file before splitting it.

Though there could be some visible text in the middle of this split segment if the original file has contained text, there is nothing else besides it, as there are no such headers like the beginning of text BOM. Hence no information can be found about encoding used for the text, as well as about any compression and encryption that might have happened earlier in the archive. All the compression and decryption relates only to that archived file itself.

The size of the file varies, though it depends on the size chosen for parts during the splitting operation and how long has the actual file been. An empty .036 file means probably that the splitting has failed or the file downloading was cut short. Integrity of this file needs to be checked by external means using the corresponding checksums or CRC.

How to convert .036 files

Reassembling is the key task here rather than conversions. Concatenate file.001, file.002, etc. until file.036 or any other number and other file volumes to restore initial file. When you deal with multipart archives then make 7-Zip/WinRAR choose file.001 as start archive. Choosing directly file.036 usually results with errors: "Can not open file as archive", "Unexpected end of archive" or plain bytes dump. Unix like OS use simple way for restoring of raw byte splits - use cat file.0?? > original.bin. Similarly for Windows - copy /b file.001 + file.002 +...+file.036 original.bin. The given technique works only in case with raw files, not with volume archives, and part order must be strict too.

After that you have to establish identity of your file by using of command line utilities - file, TrID, 7-Zip’s own test, or original download page before file opens. In the case if the set is multipart archive, then firstly decompressed the file and compressed it again in the ZIP format, or TAR or even in 7z format. The file decompressed in the such way has no volumes anymore and archive comments, solid compression scheme, recovery records and some non-supported attributes like dates are gone also. Reconstructed disk images, videos and documents from multipart set have to be also fully built. It is forbidden to convert just .036 member because of incompleteness.

Convert toToolCommand / note
Original unsplit file cat cat file.0?? > original.bin Works only for raw byte-split sets whose parts are named in lexical order, such as file.001 through file.036; include all parts, not only .036.
Original unsplit file Windows Command Prompt copy copy /b file.001+file.002+file.003+file.004+file.005+file.006+file.007+file.008+file.009+file.010+file.011+file.012+file.013+file.014+file.015+file.016+file.017+file.018+file.019+file.020+file.021+file.022+file.023+file.024+file.025+file.026+file.027+file.028+file.029+file.030+file.031+file.032+file.033+file.034+file.035+file.036 original.bin For raw split files on Windows; the part order must be exact.
Extracted contents 7-Zip 7z x file.001 Use the first volume, not file.036. 7-Zip will read subsequent numbered parts automatically if they are in the same folder.
ZIP archive 7-Zip 7z x file.001 -oextracted && 7z a output.zip extracted/* Useful when the split set is a multi-volume archive and you want a single ZIP; archive comments, recovery records, and volume boundaries are not preserved.
TAR archive GNU tar after reassembly cat file.0?? > original.bin && tar -cf output.tar original.bin This wraps the reassembled payload into a TAR file; it does not interpret the payload unless it is itself an archive.

Common problems and fixes

Such problems might come across as “Cannot open file as archive”, “Unexpected end of archive”, “CRC failed”, “You need to start extraction from a previous volume” or “Next volume is required”. First, it is necessary to make sure that the volume set contains .001 to .036 segments along with any further ones (i.e., no .017 or .029 is missing even though .036 has been uploaded fully). The filenames should be equal to one another with regard to the first elements and with the usage of the zero padding (e.g., file.001 - file.002 - file.036).

When .036 rather than .001 file is taken as a starting point for uncompression, most tools would not manage it, having the central header/ metadata/split context saved elsewhere. Opening .001 is a typical solution here. With the damage of the middle segment, the files, whose compressed content runs across that borderline, often suffer CRC failings and “Unexpected end of archive” issues (and the way to fix them is to just repeat downloading of that .017 or .029 or whatever and try to extract it once more). Passworded archiving leads to similar situations if the entered password was wrong. There are different volume archives and some just consist of raw files: it is possible that 7-Zip would be unable to handle the process and the original authoring program should help (WinRAR, PeaZip, GSplit or HJSplit). Also in some cases it won’t be possible to reconstruct files in FAT32 format, as it can work only with the files smaller than 4 GigaBYTES.

Security considerations

The single .036 section poses very little threat, because by definition it consists of only one numbered block of payload and cannot be executed separately without being put together with other blocks into one piece. But once the reassembling process is performed, it might create EXE executable program installer, a script, macro-based DOCM / XLSM file, virtual hard drive image or an archive such as ZIP, RAR or 7z which contains any exploit inside. There are multiple part archive files that do not make it clear what file will be reassembled out of them at all until you actually put them into place and reconstruct the original piece. Please do this using the most recent 7-Zip / WinRAR /WinZip /Keka/PeaZip to avoid potential weaknesses in file extraction code that have been discovered before. It is forbidden to deliver unknown set of .036 files online if they might potentially contain sensitive backups/PHOTOs/programming sources/database or document dump.

History and versions

Numbered split files became widespread throughout the 1980s and 1990s as a period during which a single file often had to be fitted onto floppy diskettes or transmitted via an upload on bulletin boards or limited network connections due to rigid restrictions as far as file sizes are concerned. There is no specific vendor who used such files nor any particular standard; many applications use the same numbering scheme; for example, the extension of the files that consist of the 36th byte range would be .036 while those that begin their numbering from 001 would have .001,.002 extensions for the consecutive bytes that followed.

In regards to the question, one can mention that it is a format and there is no specific specification for it at IANA; also, no standardization body developed that file extension since its popularity was mostly due to the tools that allowed to produce such kind of files. Nowadays thanks to high broadband Internet connectivity, bigger sizes of file systems it does not become popular; however, it is still in practice due to clouds limits, forums attachments and Usenet messages. Best case scenario is always keeping all the fragments as a set, making sure checksum match and using starting fragment from the beginning, in other words from .001 fragment.

Beginning portion would usually be .001 since it usually starts with the header. .002 until .035 refer to past volumes and the mere presence of .036 volume file doesn't guarantee the set ends there because files beyond index .037 can actually occur. Archive with extensions .7z.001, .zip.001, and like compound types are easier to identify since this implies an already well-known archive class. Rar volumes use .rar with .r00 and/or .r01 where archive semantics are definitely better known. ZIP Split archivers are usually represented with such combinations like .z01/.z02/.zip, and it is clearly the archive type but not just fragmented binary data pieces. .part and .crdownload extension stands for an incompleteness of download (i.e., not split archive volume). Checksums, namely sfv, md5 or sha256, will often be connected with this set, and reconstructed piece of archive would have such extensions as .iso, .img, .mkv, .zip, .7z and others.
