Summary

Remove cache files

Properties

Name Direction Type Default Description

AgeInDays Input number 14 If any file is more than this many days old, it will be deleted. 0 means remove everything

Description

Use this algorithm to remove cache files.

As described in algorithm CreateCacheFilename, cache files are named in the form of <prefix>_<sha1>.nxs or <sha1>.nxs. This algorithm delete all such files from the default cache directory or the user-defined cache directory, if supplied.

The name matching is done using regex (40 characters of numbers plus a-f letters). Therefore if a user created a file in the designated directory that happens to have the same pattern, it will be deleted.

The algorithm also take parameter “AgeInDays”, which allow users to preserve cache files that are newer. For example, if AgeInDays is 5, the latest 5 days of cache files will be preserved. By default, AgeInDays is 14 days or two weeks.

Usage

Example:

# Execute
CleanFileCache(
    CacheDir = "/path/to/mycache",
    AgeInDays = 5,
    )
