One of FTPGetter features is a possibility to download and upload groups of files using a file mask. What is it used for and how does it work?

You need to upload to the server or download from the server only files with txt extension. The file mask for this case with look this way:

*.txt - only files with txt extension.

For files of other type (e.g. php scripts) the mask will be the following:

*.php - only files with php extension.

You need to process files, names or extensions of which start with, end with or contain definite symbols:

2005*.* - all files, names of which start with 2005 match to this mask: 2005.txt, 2005_10.rep, 2005-all.html;
 

*2005*.txt - all files, names of which contain 2005 and which have txt extension, match to this mask: 102005.txt, 200510.txt, 2005.txt, all_2005_all.txt;
 

??-??-2005.??? - all files with three-symbol extension and name of the type: 10-10-2005.rep, aa-bb-2005.txt. File 10-10-2005.gz doesn't match to the aforesaid mask as its extension has only two symbols;
 

??[a-z].* - all files with any extension, names of which have three symbols where the last symbol is from the range from a to z, match to this mask: 12a.html, qwe.txt, 88z.pl. File 123.txt doesn't match to the aforesaid mask as its last symbol is not from the range a-z;
 

*[abc].* - all files with any extension and any name length, but with the last symbol a, b or c in the name, match to this mask: 2005a.txt, 2005c.html, bc.pl. File with the name 2005f.txt doesn't match to the aforesaid mask as its last symbol is not a, b or c.
 

[^a-z]*.txt - all files with txt extension, names of which do not start with symbols a-z, match to this mask: 123.txt, 1_2.html. File with the name report.html doesn't match to the aforesaid mask as its name begins with the symbol r, which is from the range a-z.
