Rev 1.8 8/24/2003 06:49:54 PM JPMugaas
API Change in the FileSystem component so that a thread is passed instead of
some data from the thread. This should also make the API's easier to manage
than before and provide more flexibility for developers writing their own
file system components.
Rev 1.7 3/10/2003 05:09:10 PM JPMugaas
MLST now works as expected with the file system. Note that the MLST means
simply to give information about an item instead of its contents.
GetRealFileName in IdFTPFileSystem now can accept the wildcard *.
When doing dirs in EPLF, only information about a directory is retruned if it
is specified.
Rev 1.6 3/6/2003 10:59:58 AM JPMugaas
Now handles the MFMT command and the MFCT (Modified Date fact) command.
Rev 1.5 3/6/2003 08:26:20 AM JPMugaas
Bug fixes.
FTP COMB command can now work in the FTPFileSystem component.
Rev 1.4 3/5/2003 03:28:06 PM JPMugaas
MD5, MMD5, and XCRC are now supported in the Virtual File System.
Rev 1.3 3/2/2003 04:54:26 PM JPMugaas
Now does recursive dir lists with the Virtual File System layer as well as
honors other switches.
Rev 1.2 3/2/2003 02:20:24 PM JPMugaas
Updated FTP File system. It now raises exceptions for errors plus load and
save have been implemented. I also implemented RMDIR.
Rev 1.1 3/2/2003 02:20:12 AM JPMugaas
Updated with some enw functionality.
Rev 1.0 11/13/2002 08:28:28 AM JPMugaas
Initial import from FTP VC.
