|
1061 Copies one or more files. |
|
1062 |
|
1063 This is a synchronous function. |
|
1064 |
|
1065 NB the following applies to files greater than or equal to 2GBytes in size |
|
1066 (2,147,483,648 bytes) : |
|
1067 - Only files smaller than 2GBytes will be copied; any larger files will be skipped and |
|
1068 processing will continue with the next file. |
|
1069 - If at least one file is smaller than 2GBytes, then KErrNone will be returned. |
|
1070 - If all files are greater than or equal to 2GBytes ,then KErrTooBig will be returned. |
|
1071 |
|
1072 One way to detect the presence of any large file(s) is to use an observer: calling |
|
1073 CFileBase::GetLastError() from MFileManObserver::NotifyFileManEnded() will return |
|
1074 KErrToBig for any file >= 2GBytes in size. |
|
1075 |
|
1076 Note: the copy operation behaves differently when MFileManObserver is used. |
|
1077 MFileManObserver should be used with multiple files as it enables you to capture the results of all file copy operations. |
|
1078 |
|
1079 If MFileManObserver is NOT used then only the result of the last |
|
1080 file copy operation is returned because the results of previous file copy operations are overwritten. |
|
1081 |
|
1082 Optionally, this function can be set to overwrite any files with the same name |
|
1083 which exist in the target directory. If the flag is set for no overwriting, |
|
1084 then any files with the same name will not be overwritten, and an error |
|
1085 (KErrAlreadyExists) will be returned for that file. Error codes may be retrieved |
|
1086 using CFileBase::GetLastError(). |
|
1087 |
|
1088 If recursive operation is set, all intermediate directories will be created, |
|
1089 including any directories in the path specified by aNew which do not |
|
1090 already exist. |
|
1091 |
|
1092 If recursive operation is not set, only the matching files located in |
|
1093 the single directory specified in anOld are copied. |
|
1094 No intermediate directories will be created; if any directories in |
|
1095 the destination path do not exist, no files will be copied, and this function |
|
1096 will return KErrPathNotFound. |
|
1097 |
|
1098 Notes: |
|
1099 1. This function operates on files only, therefore: |
|
1100 1.1 In contrast to the way CFileMan::Move() and CFileMan::Rename() |
|
1101 behave, the behaviour of the copy operation does not depend on the presence |
|
1102 or absence of a trailing backslash ("\") character. Therefore it is only |
|
1103 possible to copy the content of the source path. It is NOT |
|
1104 possible by use of a trailing backslash ("\") character to request that the |
|
1105 last directory level plus its content be copied to the target path. |
|
1106 |
|
1107 This means that the following two example copy operations will behave |
|
1108 identically |
|
1109 |
|
1110 @code |
|
1111 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1112 ... |
|
1113 fm->Copy(_L("C:\\SRC\\"), _L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1114 fm->Copy(_L("C:\\SRC"), _L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1115 @endcode |
|
1116 |
|
1117 because they will be interpreted as follows: |
|
1118 @code |
|
1119 fm->Copy(_L("C:\\SRC\\*"),_L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1120 @endcode |
|
1121 |
|
1122 1.2 If there is no file to operate on i.e. if source directory is empty, the |
|
1123 function will do nothing and return error code KErrNotFound. |
|
1124 |
|
1125 2. Files can be copied across drives. |
|
1126 |
|
1127 3. Open files can be copied if they have been opened using |
|
1128 the EFileShareReadersOnly file share mode. |
|
1129 |
|
1130 4. Read-only, hidden and system files can be copied and |
|
1131 the source file's attributes are preserved in the target file. |
|
1132 |
|
1133 @param anOld Path indicating the file(s) to be copied. |
|
1134 Any path components which are not specified here will be |
|
1135 taken from the session path. |

|
1386 no files will be moved, and this function will return KErrPathNotFound. |
|
1387 |
|
1388 The behaviour of the move operation is sensitive to the presence (or absence) |
|
1389 of a trailing backslash ("\") character on the end of the source path: |
|
1390 - if there is a trailing backslash ("\") character, then the operation moves |
|
1391 the content of the last directory level only. |
|
1392 - if there is no trailing backslash ("\") character, then the operation behaves |
|
1393 recursively by default and moves both the last directory level and all of its content. |
|
1394 Notice that no trailing backslash ("\") implies moving files recursively automatically. |
|
1395 |
|
1396 For example, if the directory level "b" contains the files F1,F2 and F3, then: |
|
1397 @code |
|
1398 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1399 ... |
|
1400 fm->Move(_L("C:\\a\\b\\"), _L("C:\\x\\y\\"), CFileMan::ERecurse); |
|
1401 @endcode |
|
1402 |
|
1403 results in files F1, F2 and F3 being moved from C:\\a\\b to C:\\x\\y, leaving the |
|
1404 path C:\\a\\b unchanged, except that it no longer contains the files |
|
1405 F1, F2 and F3. |
|
1406 |
|
1407 If there is no trailing backslash character, for example: |
|
1408 @code |
|
1409 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1410 ... |
|
1411 fm->Move(_L("C:\\a\\b"), _L("C:\\x\\y\\"), CFileMan::ERecurse); |
|
1412 @endcode |
|
1413 |
|
1414 then both the directory level "b" and its contents are moved. This means that |
|
1415 there is no longer a directory "b" under C:\\a. Instead there is a new |
|
1416 directory structure C:\\x\\y\\b and the files F1, F2, and F3 now exist |
|
1417 under C:\\x\\y\\b. Also if "b" contains subdirectories, then these are also |
|
1418 moved along with "b". |
|
1419 |
|
1420 If there is no trailing backslash character and the switch is not set, i.e. |
|
1421 0 is passed as an argument, the operation behaves the same way as by passing |
|
1422 CFileMan::ERecurse flag. |
|
1423 |
|
1424 for example: |
|
1425 @code |
|
1426 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1427 ... |
|
1428 fm->Move(_L("C:\\a\\b"), _L("C:\\x\\y\\"), 0); |
|
1429 @endcode |
|
1430 |
|
1431 The example above produces the same output as: |
|
1432 |
|
1433 @code |
|
1434 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1435 ... |
|
1436 fm->Move(_L("C:\\a\\b"), _L("C:\\x\\y\\"), CFileMan::ERecurse); |
|
1437 @endcode |
|
1438 |
|
1439 Notes: |

1440 |
|
1441 -# Read-only, hidden and system files can be moved and the source file's |
|
1442 attributes are preserved in the target file, but open files cannot |
|
1443 be moved. Attempting to move an open file will return an error for |
|
1444 that file, as retrieved by CFileBase::GetLastError(). |
|
1445 |
|
1446 @param anOld Path indicating the files to be moved. May be either a full path, or |
|
1447 relative to the session path. Note that if you specify a directory level, |
|
1448 then the behaviour of the move operation is sensitive to the presence |
|
1449 (or absence) of a trailing backslash ("\") character. Any path components |
|
1450 which are not specified here will be taken from the session path. See the |
|
1451 main description for the detailed explanation. |
|
1452 @param aNew Path indicating the directory into which the file(s) are to be moved. |
|
1453 Any path components which are not specified here will be taken from the session path. |
|
1454 @param aSwitches CFileMan::EOverWrite to overwrite files with the same name; |
|
1455 CFileMan::ERecurse for recursion. |
|
1456 By default, the synchronous variant of this function operates non-recursively and |
|
1457 with overwriting. And no trailing backslash ("\") character at the end of source path |
|
1458 always means CFileMan::ERecurse. |
|
1459 |
|

|
1461 codes. |

|
1890 /** |
|
1891 Renames one or more files, or a directory |
|
1892 |
|
1893 This is a synchronous function. |
|
1894 |
|
1895 The function can also be used to move files by specifying different destination |
|
1896 and source directories. |
|
1897 |
|
1898 Some rules for using CFileMan::Rename(): |
|
1899 |
|
1900 1. General rules: |
|
1901 |
|
1902 1.1. Trailing backslash ("\") in either source path (aName) or target path (aNewName) |
|
1903 will be interpreted to "\*.*"; |
|
1904 |
|
1905 For example, following code should behave identically: |
|
1906 @code |
|
1907 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1908 ... |
|
1909 fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\")); |
|
1910 fm->Rename(_L("C:\\SRC\\*.*"), _L("C:\\TRG\\")); |
|
1911 fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\*.*")); |
|
1912 fm->Rename(_L("C:\\SRC\\*.*"), _L("C:\\TRG\\*.*")); |
|
1913 @endcode |
|
1914 |
|
1915 1.2 The behaviour of the rename operation is sensitive to the presence (or absence) of |
|
1916 a trailing backslash ("\") character on the end of the target path (aNewName); |
|
1917 |
|
1918 For example, under all other constraints (see rules 2. and 3.), |
|
1919 @code |
|
1920 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1921 ... |
|
1922 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\")); |
|
1923 @endcode |
|
1924 will result in renaming "C:\\SRC" to "C:\\TRG\\SRC", while |
|
1925 @code |
|
1926 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1927 ... |
|
1928 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
1929 @endcode |
|
1930 will result in renaming "C:\\SRC" to "C:\\TRG". |
|
1931 |
|
1932 2. Renaming file(s): |
|
1933 |
|
1934 2.1 Wildcards: |
|
1935 |
|
1936 A file's name and extension are interpreted separately, for example: |
|
1937 |
|
1938 @code |
|
1939 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1940 ... |
|
1941 fm->Rename(_L("C:\\SRC\\1234.567"), _L("C:\\TRG\\AB*CD.TXT")); |
|
1942 @endcode |
|
1943 renames the source file to file "C:\\TRG\\AB34CD.TXT". |
|
1944 |
|
1945 Wildcards can be used for renaming multiple files, for example; |
|
1946 @code |
|
1947 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1948 ... |
|
1949 fm->Rename(_L("C:\\SRC\\*.567"), _L("C:\\TRG\\*.TXT")); |
|
1950 @endcode |
|
1951 renames all the file under "C:\\SRC\\" having extension ".567" to the files under |
|
1952 "C:\\TRG\\" having extension ".TXT". |
|
1953 |
|
1954 2.2 An option is provided to allow the user to overwrite any files with the same |
|
1955 name which may exist in the target directory; If the flag is set for no overwriting, |
|
1956 any files with the same name will not be overwritten, and an error (KErrAlreadyExists) |
|
1957 will be returned for that file, as retrieved by CFileBase::GetLastError(). |
|
1958 |
|
1959 2.3 It can only operate non-recursively, so that only the matching files located |
|
1960 in the single directory specified by anOld may be renamed. |
|
1961 |
|
1962 2.4 Trying to rename file(s) to existing directory(ies) will fail; |
|
1963 |
|
1964 For example, giving following directory structure: |
|
1965 @code |
|
1966 C:\SRC\ITEM01 |
|
1967 C:\SRC\ITEM02 |
|
1968 C:\TRG\ITEM01\ |
|
1969 C:\TRG\ITEM02\ |
|
1970 @endcode |
|
1971 |
|
1972 Following code will fail: |
|
1973 @code |
|
1974 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1975 ... |
|
1976 fm->Rename(_L("C:\\SRC\\ITEM01"), _L("C:\\TRG\\ITEM01")); |
|
1977 fm->Rename(_L("C:\\SRC\\ITEM*"), _L("C:\\TRG\\ITEM*")); |
|
1978 fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\")); |
|
1979 @endcode |
|
1980 |
|
1981 3. When renamnig a directory: |
|
1982 |
|
1983 3.1. Only when the trailing backslash ("\") is missing from the source path (aName), |
|
1984 will the source directory be renamed, otherwise, see rule 1.1. |
|
1985 |
|
1986 For example, following code will result in moving "C:\SRC" directory including all |
|
1987 its contents: |
|
1988 @code |
|
1989 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1990 ... |
|
1991 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
1992 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\")); |
|
1993 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\*.*")); |
|
1994 @endcode |
|
1995 |
|
1996 3.2. Wildcards can not be used for moving directories; |
|
1997 |
|
1998 3.3. Overwriting is not permitted; |
|
1999 |
|
2000 For example, giving directory structure as following: |
|
2001 @code |
|
2002 C:\SRC\FILE.TXT |
|
2003 C:\TRG\ |
|
2004 C:\TRG\SRC\ |
|
2005 @endcode |
|
2006 |
|
2007 following code will fail: |
|
2008 @code |
|
2009 CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2010 ... |
|
2011 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
2012 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\")); |
|
2013 fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\*.*")); |
|
2014 @endcode |
|
2015 |
|
2016 4. Notes: |
|
2017 |
|
2018 4.1. The target and source directories must be on the same drive. |
|
2019 |
|
2020 4.2. Read-only, hidden and system files can be moved and the source file's |
|
2021 attributes are preserved in the target file, but open files cannot |
|
2022 be moved. Attempting to move an open file will return an error for |
|
2023 that file, as retrieved by CFileBase::GetLastError(). |
|
2024 |
|
2025 @param aName Path specifying the file(s) to be renamed. Any path components |
|
2026 which are not specified |
|
2027 here will be taken from the session path. |
|
2028 @param aNewName Path specifying the new name for the files and/or |
|
2029 the new directory. Any directories specified in this path |
|
2030 that do not exist, will be created. Any path components which |
|
2031 are not specified here will be taken from the session path. |
|
2032 @param aSwitches Specify zero for no overwriting; |
|
2033 CFileMan::EOverWrite to overwrite files with the same name. |
|
2034 This function cannot operate recursively. |
|
2035 |
|
2036 @return KErrNone if successful, otherwise one of the other system-wide error |
|
2037 codes. |
|
2038 |
|
2039 @see CFileBase::GetLastError() |
|
2040 |
|
2041 @capability Dependent If either aName or aNewName is /Sys then Tcb capability is required. |
|
2042 @capability Dependent If either aName or aNewName begins with /Private and does not match |
|
2043 this process' SID then AllFiles capability is required. |
|
2044 @capability Dependent If either aName or aNewName is /Resource then Tcb capability is required. |
