11 14 Sep 02 SHL Drop obsolete debug code
12 14 Oct 02 SHL Drop obsolete debug code
13 10 Nov 02 SHL docopyf - don't forget to terminate longname
14 optimize longname logic
15 01 Aug 04 SHL Rework lstrip/rstrip usage
16 28 May 05 SHL Drop debug code
17 14 Jul 06 SHL Use Runtime_Error
18 20 Aug 07 GKY Move #pragma alloc_text to end for OpenWatcom compat
19 01 Sep 07 GKY Use xDosSetPathInfo to fix case where FS3 buffer crosses 64k boundry
20 29 Feb 08 GKY Use xfree where appropriate
21 19 Jul 08 GKY Modify MakeTempName for use making temp directory names
22 08 Mar 09 GKY Removed variable aurguments from docopyf and unlinkf (not used)
23 28 Jun 09 GKY Added AddBackslashToPath() to remove repeatative code.
24 12 Jul 09 GKY Add xDosQueryAppType and xDosAlloc... to allow FM/2 to load in high memory
25 13 Jul 09 SHL Drop obsolete code
26 22 Jul 09 GKY Delete .LONGNAME EA if it becomes the filename on a copy or move.
27 19 Oct 09 SHL Correct copyf regression when moving to save volume
28 31 Mar 10 JBS Correct copyf which was creating 8.4, not 8.3, temporary names
29 26 Aug 11 GKY Add a low mem version of xDosAlloc* wrappers; move error checking into all the
30 xDosAlloc* wrappers.
31 04 Aug 12 GKY Changes to use Unlock to unlock files if Unlock.exe is in path both from menu/toolbar and as part of copy, move and
32 delete operations
33 04 Aug 12 GKY Changes to allow copy and move over readonly files with a warning dialog; also added a warning dialog for delete of
34 readonly files
35 10 Mar 13 GKY Improvrd readonly check on delete to allow cancel and don't ask again options
36 09 Feb 14 GKY Modified wipeallf to allow suppression of the readonly warning on delete
37 of temporary files
38 16 Feb 14 GKY Rework readonly check on delete code so it actually works in a logical way
39 and so it works with move to trashcan inabled.
40 22 Feb 14 GKY Fix wipeallf to recurss properly
41 22 Feb 14 GKY Fix warn readonly yes don't ask to work when recursing directories.
42 19 Jul 14 GKY Fix redundant error message following selection of no for unlocking a file
