The File Mask entry field is used to input a file filter mask. Standard use of wildcards is supported. An asterisk (*) means 'all or all after'. For example, the mask A* would display all files beginning with the letter 'A'. The 'all or all after' specification terminates at the extension. Therefore the mask *.txt would filter and display all files with the file extension .txt, and the mask os2*.ini would display only those filenames with the .ini extension starting with the three characters 'os2'. The question mark (?) is used to substitute "Any" for an individual character. Thus the mask myfile??.txt would display myfile files with the txt extension, e.g, myfile01.txt, myfile02.txt, myfile03.txt; it would not, however, display myfile1.txt since there are not sufficient characters to occupy the wildcard specified.
See File Filters for supported file masks. The File Filter dialog may be used to enter a filter in this field. If the File Filter dialog is not used and the File Search mode is the current mode, clicking on a file in the FS/2 Files window will set the selected file name in the field. Any entry may be manually edited at any time.
File masks are limited to 128 characters.
The entry in this field may be saved to a rotary 10 filed list by pressing the Save button. Use the dropdown list to select from the saved list.
