Labels:text | screenshot | font OCR: NAME fstat - display complete list of currently open files SYNOPS IS fstat DESCRIPTION fstat.com is a program to display all of the currently open files and devices known to the system. It also shows length, current offset, number of handles referring to this file, drive or device type, and program which opened the file. The standard devices CON, AUX, PRN, etc. are also listed since they use file handles. The program might be useful for diagnosing "too many files open" type messages, since it will show what files are in use by TSRs in addition to those opened by a foreground program. It works by using DOS service 52H, the "list of lists" interrupt, which returns pointers to most of the internal DOS kernel tables, including the file tables. It should work for all DOS versions 2+, although only 3+ can find out the name of the program which opened any given file. There is some version specific code for 4.x and it is possible that this may not work on all systems since the contents of the system tables are not fully documented. SEE ALSO BUGS This seems to work, but it would be nice if this information were made "official" instead of needing to rely on the usenet "interrupt list" for the necessary information It is usually not possible to retrieve the name of a shell (such as command.com) so it is listed as "-shell-".
