# removefiles

Purpose
Remove files selected using file name patterns.
Synopsis
`procedure removefiles(opt:integer, dir:text,filters:text)`
`procedure removefiles(filters:text)`
Arguments

opt | Options (several options can be combined):
SYS_RECURS | Recursive search in subdirectories
SYS_NODIR | Do not remove directories (only files)
SYS_DIRONLY | Remove only directories
dir | Base directory for the search (default: current directory)
filters | File name filters (default: all files removed)

Example
The following deletes directory "mydir" including its content:

    removefiles(SYS_RECURS,"mydir","*")
    removedir("mydir")

Further information
1. The filters argument consists in a list of patterns separated by the symbol ";". A pattern is composed of a path (using the usual operating system conventions) which last component may include wildcard characters "*" (any text of any length), "?" (any single character) and "|" (logical "or"). For instance "bin/*.exe;models/*.mos|*.dat" will select all files with extension ".exe" in the "bin" directory as well as files with extension ".mos" and ".dat" in the "models" directory.
2. File name matching is achieved using function pathmatch and differences may be observed depending on the operating system ( e.g. file names are case sensitive under Posix systems but not under Windows).
