M0 compression rar

Delete files after archiving and place them to Recycle Bin. Available in Windows version only. Delete files after archiving. Before deleting file data. Please be aware that such approach is designed for usual. This switch indicates that directory records are not to be. When extracting such archives,. RAR creates non-empty directories based on paths of files.

Information about empty directories is. All attributes of non-empty directories except a name. If -ed is used with 'm' command or -df switch, RAR will not.

Not supported for RAR 5. By default, RAR adds an "end of archive" block to the end of. It allows to skip external data like. For example, if an archive. This switch cannot be used with volumes, because the end. This switch enables files to be added. Do not store the path entered. This is equivalent to the commands:. Store full file paths except the drive. This switch stores full file paths including the drive.

Drive separators colons. If you use -ep3 when extracting, it will change. If the user. This switch can help to backup several disks to the same. For example, you may run:. But be cautious and use -ep3 only if you are sure that. In other words, use it if you have created an archive yourself. This switch allows to overwrite.

Specifies file exclude or include attributes mask. So if result of bitwise AND between. Only those files which have at least one attribute specified. In Windows version is also possible to use symbols D, S, H,.

A and R instead of a digital mask to denote directories. The order in which the attributes are given is not significant. Unix version supports D and V symbols to define directory. May be used with archive extraction or creation. The command string "a -f" is equivalent to the command 'f', you. This switch is similar to -p[p], but switch -p encrypts. This switch encrypts all sensitive archive areas.

Without a password it is impossible to view even the list of. File data integrity in RAR archive is protected by checksums. Since CRC32 is the default algorithm, you may need -htc only to. CRC32 output is 32 bit length.

While CRC32 properties are. In other words, if two files have the same CRC32,. BLAKE2sp output is bit. Being a cryptographically strong. BLAKE2sp error detection property is also more reliable than. If archive headers are unencrypted no switch -hp , checksums. Do not expect such encrypted. This switch is supported only by RAR 5. You can see checksums of archived files using 'vt' or 'lt'.

Switch -idc disables the copyright string. Switch -idd disables "Done" string at the end of operation. Switch -idp disables the percentage indicator. Switch -idq turns on the quiet mode, so only error messages. It is allowed to use several modifiers at once,. Send archive by email. Windows version only. Attach an archive created or updated by the add command. You need to have a MAPI compliant email. You may enter a destination email address directly.

In the latter case you. It is possible. If you append a dot character to -ieml, an archive will be. If the switch is used when creating a multivolume archive,. Log errors to file registered version only. Write error messages to rar. If optional 'name'. Windows: rar. If 'name' parameter includes a file name without path,. RAR will create the log file in the default directory. Include both path. By default, log file uses UTF little endian encoding,.

The hardware must. RAR, by default, deletes files with checksum errors. The switch -kb specifies that files. This switch allows to write archive and file names to specified.

Its behavior is defined by 'fmt' string, which can include one. A - write archive names to log file. If RAR creates or processes. F - write processed file names to log file. It includes.

P - if log file with specified name is exist, append data. U - write data in Unicode format. If neither 'A' nor 'F' are specified, 'A' is assumed. If 'name' is not present, RAR will use the default rarinfo. It is allowed to specify several -log switches in the same. This switch can be particularly useful, when you need to process. For example, in Windows batch file. If this switch is not specified, RAR uses -m3 method. Specify a version of archiving format.

Use -ma5 or just -ma to create RAR 5. Use -ma4 in case you need to override -ma5 saved. This switch is used only when creating a new archive. It is ignored when updating an existing archive. Set advanced compression parameters. This switch is intended mainly for benchmarking and. In the real environment it is usually better. Please note that improper use of this switch may lead. It has the following syntax:. It may have the following values:. A - audio compression;.

C - true color RGB data compression;. D - delta compression;. E - bit x86 executables compression;. I - bit Intel Itanium executables compression;. T - text compression. If no sign is specified, RAR will choose modules automatically,. Switch -mc- disables all optional modules and allows only.

Audio compression, delta compression:. RAR splits multibyte channels to bytes, for example,. Text compression algorithm provides noticeably higher compression. But it cannot utilize several CPU cores. Also its decompression speed is much slower than in general.

This is why. You can specify. Usually a higher value slightly increases the compression ratio. In case of lack of memory the result may be negative. Higher order values decrease both compression and decompression. Higher values may increase the compression ratio, but note. Select the dictionary size. Sliding dictionary is the memory area used by compression.

If size of file being compressed or total files size in case. For RAR 4. For RAR 5. You can use 'k', 'm' and 'g' modifiers to specify the size. If no modifier is specified, megabytes are assumed,. When archiving, RAR needs about 6x memory of specified. When extracting, slightly more. RAR can reduce the dictionary size if it is significantly.

It helps to reduce memory. Specify file types to store. Specify file types, which will be stored without compression. This switch may be used to store already compressed files,. For example, -msrar;zip;jpg will. It is also allowed to specify wildcard. Several -ms switches are permitted, such as -msrar -mszip. In Unix -ms switch containing several file types needs to be. It protects semicolons from processing. Set the number of threads. It defines the recommended maximum number of active threads.

While RAR attempts to follow. If -mt switch is not specified, RAR will try to detect. Apply the mask as an additional filter to included file list. Wildcards can be used both in the name and file parts of. See switch -x description for details on mask syntax. You can specify the switch '-n' several times. This switch does not replace usual file masks, which still. It is an additional. It can help to. If you use -n without the list file name.

This switch does not replace usual list files or file masks,. It is an additional filter limiting processed files only to. RAR saves Compressed file attributes. If archiving files include several hard links, store the first. When extracting. You must not delete or rename the first hard link in archive. If you modify the first link,. Extraction command must involve the first. Save identical files as references. Switch -oi0 or just -oi- turns off identical file processing,. It can be used to.

If -oi1 or just -oi is specified, RAR analyzes the file. If several identical files. It allows to reduce the archive size, but applies some. You must not delete or rename. If you modify the first file,.

Extraction command must involve the first file. It is recommended to use -oi only if you compress a lot of. If all identical files are small enough to. Switch -oi2 is similar to -oi1, with the only difference:. Switches -oi3 and -oi4 allow to utilize RAR to generate. Though you still need to provide. If -oi3 is used, file sizes and names are displayed.

Switch -oi4 displays bare file names and skips the first. If this parameter is not. Switches -oi1 and -oi2 are supported only by RAR 5. Save contents of current directory to archive. Store identical files as references. Save symbolic links as links, so file contents is not archived.

In Windows version it also saves reparse points as links. Such archive entries are restored as symbolic links. Supported both for RAR 4. In Windows you may need to run RAR as administrator to create.

RAR adds all links regardless of target when archiving with. When extracting, by default, RAR skips symbolic. You can enable. Links pointing to directories outside of extraction destination. Enable their extraction. Links with relative paths inside of destination directory. Renamed file will get the name like. This switch has meaning only for NTFS file system and allows. You may need to specify it when archiving if you use software. Streams are not saved for NTFS encrypted files.

Unix RAR version saves file owner and group when using. Windows version stores owner, group, file permissions and. Note that only NTFS file system supports. Can be used both when extracting. RawIOBase interface, so it can be further wrapped with io. BufferedReader and io. On older Python where io module is not available, it implements only. For longer files using open may be better idea.

File modification timestamp. As tuple of year, month, day, hour, minute, second. File modification time. Optional time field: creation time. As datetime object. Optional time field: last access time. Optional time field: archival time. Bases: io. Base class for file-like object that RarFile.

On compresses files its slow - forward seeking happends by reading ahead, backwards by re-opening and decompressing from the start. Bases: datetime. You can drag or drop the files onto the upload box or you can click directly on the box to choose files from your desktop. For selecting multiple files you can press the 'shift' button.
