Archiving options: Options

Test archived files

Test files after archiving. This option is especially useful if "Delete files after archiving" is also enabled. In this case files will be deleted only if the archive had been successfully tested.

Create separate archives

Place every selected file and folder to individual archive. Archive names are generated as selected item name followed by appropriate archive extension.

Use BLAKE2 file checksum

File data integrity in RAR archive is protected by checksums calculated and stored for every archived file. By default, RAR uses 32 bit length CRC32 checksum. If this option is on, 256 bit BLAKE2sp is used instead of CRC32. While CRC32 is reliable enough to detect most of errors, BLAKE2 has even better error detection properties at cost of slower calculation and slightly larger archive size. This option is available only for archives in RAR 5.0 format.

Show archiving time

Display the dialog containing the total archiving time on successful completion of archiving operation. Might be useful when benchmarking different archiving modes.

Archive name mask

Append the current date string to an archive name when creating an archive. Useful for daily backups. The date string is formatted by the specified mask, which may include following characters:

Y year
M month
MMM  month as text string (Jan, Feb, etc.)
W a week number (a week starts with Monday)
A day of week (Monday is 1, Sunday is 7)
D day of month
E day of year
H hours
M minutes (treated as minutes if encountered after hours)
I minutes (treated as minutes regardless of hours position)
S seconds
N archive number (numeric value starting from 1).
When archiving, RAR searches for already existing archive with generated name and if found, increments the archive number until generating an unused name. 'N' format character is not supported when creating volumes.

Each of format string characters listed above represents only one character added to archive name. For example, use WW for two digit week number or YYYY to define the four digit year.

If the first character in the format string is '+', positions of the date string and base archive name are exchanged, so a date will precede an archive name.

The format string may contain optional text enclosed in '{' and '}' characters. This text is inserted into archive name.

All other characters of format string are added to archive name without changes.
