In another tip (Checking the Archive Attribute with Robocopy) we saw that we can have Robocopy perform operations based on file attributes. You can also affect its operation based on file sizes and ages.
For file sizes, you'd use the switches /MAX:n and /MIN:n, where "n" specifies the sizes of the files, in bytes, that are to be excluded from the copy. As an example, specifying /MAX:10000 tells Robocopy to exclude from copying any file that is larger than 10,000 bytes.
You can also alter what is copied based on the files' ages. The following command-line switches are used for this:
The only trick to using these options is in understanding what the "n" means. Depending upon its value, "n" can either represent days or a date. If "n" is less than 1900 then "n" is assumed to be a number of days, otherwise "n" is a date of this form: YYYYMMDD.
