/** |
|
931 |
Sets or clears attributes for one or more files using two bitmasks |
|
932 |
||
933 |
This is a synchronous function. |
|
934 |
||
935 |
The first bitmask specifies the attributes to be set. |

The second specifies the attributes to be cleared. |

937 |
The date and time of the files' last modification can also be changed. |
|
938 |
||
939 |
The function can operate recursively or non-recursively. |
|
940 |
When operating non-recursively, only the matching files located in the directory |

specified in aName are affected. When operating recursively, all matching files |

Notes: |
|
945 |
||
946 |
1. A panic is raised if any attribute is specified in both bitmasks. |
|
947 |
||
948 |
2. Attempting to change the attributes for an open file results in an error |
|
949 |
for that file, as retrieved by CFileBase::GetLastError(). |
|
950 |
||
951 |
3. An attempt to set or clear the KEntryAttDir or KEntryAttVolume attribute |
|
952 |
for a file or directory will have no effect. |

1073 |
/** |
|
1074 |
Copies one or more files. |
|
1075 |
||
1076 |
This is a synchronous function. |
|
1077 |
||
1078 |
NB the following applies to files greater than or equal to 2GBytes in size |
|
1079 |
(2,147,483,648 bytes) : |
|
1080 |
- Only files smaller than 2GBytes will be copied; any larger files will be skipped and |
|
1081 |
processing will continue with the next file. |
|
1082 |
- If at least one file is smaller than 2GBytes, then KErrNone will be returned. |
|
1083 |
- If all files are greater than or equal to 2GBytes ,then KErrTooBig will be returned. |
|
1084 |
||
1085 |
One way to detect the presence of any large file(s) is to use an observer: calling |
|
1086 |
CFileBase::GetLastError() from MFileManObserver::NotifyFileManEnded() will return |
|
1087 |
KErrToBig for any file >= 2GBytes in size. |
|
1088 |
||
1089 |
Note: the copy operation behaves differently when MFileManObserver is used. |
|
1090 |
MFileManObserver should be used with multiple files as it enables you to capture the results of all file copy operations. |
|
1091 |
||
1092 |
If MFileManObserver is NOT used then only the result of the last |
|
1093 |
file copy operation is returned because the results of previous file copy operations are overwritten. |
|
1094 |
||
1095 |
Optionally, this function can be set to overwrite any files with the same name |
|
1096 |
which exist in the target directory. If the flag is set for no overwriting, |
|
1097 |
then any files with the same name will not be overwritten, and an error |
|
1098 |
(KErrAlreadyExists) will be returned for that file. Error codes may be retrieved |
|
1099 |
using CFileBase::GetLastError(). |
|
1100 |
||
1101 |
If recursive operation is set, all intermediate directories will be created, |
|
1102 |
including any directories in the path specified by aNew which do not |
|
1103 |
already exist. |

If recursive operation is not set, only the matching files located in |
1131 |
the single directory specified in anOld are copied. |
|
1132 |
No intermediate directories will be created; if any directories in |
|
1133 |
the destination path do not exist, no files will be copied, and this function |
|
1134 |
will return KErrPathNotFound. |
|
1135 |
||
1136 |
Notes: |
|
1137 |
1. This function operates on files only, therefore: |
|
1138 |
1.1 In contrast to the way CFileMan::Move() and CFileMan::Rename() |
|
1139 |
behave, the behaviour of the copy operation does not depend on the presence |
|
1140 |
or absence of a trailing backslash ("\") character. Therefore it is only |
|
1141 |
possible to copy the content of the source path. It is NOT |
|
1142 |
possible by use of a trailing backslash ("\") character to request that the |
|
1143 |
last directory level plus its content be copied to the target path. |
|
1144 |
||
1145 |
This means that the following two example copy operations will behave |
|
1146 |
identically |
|
1147 |
||
1148 |
@code |
|
1149 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1150 |
... |
|
1151 |
fm->Copy(_L("C:\\SRC\\"), _L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1152 |
fm->Copy(_L("C:\\SRC"), _L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1153 |
@endcode |
|
1154 |
||
1155 |
because they will be interpreted as follows: |
|
1156 |
@code |
|
1157 |
fm->Copy(_L("C:\\SRC\\*"),_L("C:\\TRG\\"), CFileMan::ERecurse); |
|
1158 |
@endcode |
|
1159 |
||
1160 |
1.2 If there is no file to operate on i.e. if source directory is empty, the |
|
1161 |
function will do nothing and return error code KErrNotFound. |
|

1437 |
/** |
|
1438 |
Moves one or more files. |
|
1439 |
||
1440 |
This is a synchronous function. |
|
1441 |
||
1442 |
Optionally, this function can be set to overwrite any files with the same name |
|
1443 |
which exist in the target directory. If the flag is set for no overwriting, |
|
1444 |
then any files with the same name will not be overwritten, and |
|
1445 |
an error (KErrAlreadyExists) will be returned for that file. |
|
1446 |
Error codes may be retrieved using CFileBase::GetLastError(). |
|
1447 |
By default, when the function is operating synchronously, files are overwritten. |
|
1448 |
||
1449 |
When this function is operating recursively, all intermediate directories will |
|
1450 |
be created, including all directories in the destination path specified |
|
1451 |
by aNew which do not already exist. |
|
1452 |
||
1453 |
If recursive operation is not set, only the matching files located in |
|
1454 |
the single directory specified in anOld are moved. No intermediate directories |
|
1455 |
will be created; if any directories in the destination path do not exist, |
|
1456 |
no files will be moved, and this function will return KErrPathNotFound. |
|
1457 |
||
1458 |
The behaviour of the move operation is sensitive to the presence (or absence) |
|
1459 |
of a trailing backslash ("\") character on the end of the source path: |
|
1460 |
- if there is a trailing backslash ("\") character, then the operation moves |
|
1461 |
the content of the last directory level only. |
|
1462 |
- if there is no trailing backslash ("\") character, then the operation behaves |
|
1463 |
recursively by default and moves both the last directory level and all of its content. |
|
1464 |
Notice that no trailing backslash ("\") implies moving files recursively automatically. |

For example, if the directory level "b" contains the files F1, F2 and F3, then: |
0 | 1467 |
@code |
1468 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1469 |

|
1470 |
fm->Move(_L("C:\\a\\b\\"), _L("C:\\x\\y\\"), CFileMan::ERecurse); |
|
1471 |
@endcode |
|
1472 |
||
1473 |
results in files F1, F2 and F3 being moved from C:\\a\\b to C:\\x\\y, leaving the |
|
1474 |
path C:\\a\\b unchanged, except that it no longer contains the files |
|
1475 |
F1, F2 and F3. |

If there is no trailing backslash character, for example: |
|
1478 |
@code |
|
1479 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
1480 |
... |
|
1481 |
fm->Move(_L("C:\\a\\b"), _L("C:\\x\\y\\"), CFileMan::ERecurse); |
|
1482 |
@endcode |
|
1483 |
||
1484 |
then both the directory level "b" and its contents are moved. This means that |
|
1485 |
there is no longer a directory "b" under C:\\a. Instead there is a new |
|
1486 |
directory structure C:\\x\\y\\b and the files F1, F2, and F3 now exist |
|
1487 |
under C:\\x\\y\\b. Also if "b" contains subdirectories, then these are also |
|
1488 |
moved along with "b". |
|
1489 |
||
1490 |
If there is no trailing backslash character and the switch is not set, i.e. |
|
1491 |
0 is passed as an argument, the operation behaves the same way as by passing |
|
1492 |
CFileMan::ERecurse flag. |

EXPORT_C TInt CFileMan::Rename(const TDesC& aName,const TDesC& aNewName,TUint aSwitches) |
|
1995 |
/** |
|
1996 |
Renames one or more files, or a directory |
|
1997 |
||
1998 |
This is a synchronous function. |
|
1999 |
||
2000 |
The function can also be used to move files by specifying different destination |
|
2001 |
and source directories. |
|
2002 |
||
2003 |
Some rules for using CFileMan::Rename(): |
|
2004 |
||
2005 |
1. General rules: |
|
2006 |
||
2007 |
1.1. Trailing backslash ("\") in either source path (aName) or target path (aNewName) |
|
2008 |
will be interpreted to "\*.*"; |
|
2009 |
||
2010 |
For example, following code should behave identically: |
|
2011 |
@code |
|
2012 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2013 |
... |
|
2014 |
fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\")); |
|
2015 |
fm->Rename(_L("C:\\SRC\\*.*"), _L("C:\\TRG\\")); |
|
2016 |
fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\*.*")); |
|
2017 |
fm->Rename(_L("C:\\SRC\\*.*"), _L("C:\\TRG\\*.*")); |
|
2018 |
@endcode |
|
2019 |
||
2020 |
1.2 The behaviour of the rename operation is sensitive to the presence (or absence) of |
|
2021 |
a trailing backslash ("\") character on the end of the target path (aNewName); |
|
2022 |
||
2023 |
For example, under all other constraints (see rules 2. and 3.), |
|
2024 |
@code |
|
2025 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2026 |
... |
|
2027 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\")); |
|
2028 |
@endcode |
|
2029 |
will result in renaming "C:\\SRC" to "C:\\TRG\\SRC", while |
|
2030 |
@code |
|
2031 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2032 |
... |
|
2033 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
2034 |
@endcode |
|
2035 |
will result in renaming "C:\\SRC" to "C:\\TRG". |
|
2036 |
||
2037 |
2. Renaming file(s): |
|
2038 |
||
2039 |
2.1 Wildcards: |
|
2040 |
||
2041 |
A file's name and extension are interpreted separately, for example: |
|
2042 |
||
2043 |
@code |
|
2044 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2045 |
... |
|
2046 |
fm->Rename(_L("C:\\SRC\\1234.567"), _L("C:\\TRG\\AB*CD.TXT")); |
|
2047 |
@endcode |
|
2048 |
renames the source file to file "C:\\TRG\\AB34CD.TXT". |
|
2049 |
||
2050 |
Wildcards can be used for renaming multiple files, for example; |
|
2051 |
@code |
|
2052 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2053 |
... |
|
2054 |
fm->Rename(_L("C:\\SRC\\*.567"), _L("C:\\TRG\\*.TXT")); |
|
2055 |
@endcode |
|
2056 |
renames all the file under "C:\\SRC\\" having extension ".567" to the files under |
|
2057 |
"C:\\TRG\\" having extension ".TXT". |
|
2058 |
||
2059 |
2.2 An option is provided to allow the user to overwrite any files with the same |
|
2060 |
name which may exist in the target directory; If the flag is set for no overwriting, |
|
2061 |
any files with the same name will not be overwritten, and an error (KErrAlreadyExists) |
|
2062 |
will be returned for that file, as retrieved by CFileBase::GetLastError(). |
|
2063 |
||
2064 |
2.3 It can only operate non-recursively, so that only the matching files located |
|
2065 |
in the single directory specified by anOld may be renamed. |
|
2066 |
||
2067 |
2.4 Trying to rename file(s) to existing directory(ies) will fail; |
|
2068 |
||
2069 |
For example, giving following directory structure: |
|
2070 |
@code |
|
2071 |
C:\SRC\ITEM01 |
|
2072 |
C:\SRC\ITEM02 |
|
2073 |
C:\TRG\ITEM01\ |
|
2074 |
C:\TRG\ITEM02\ |
|
2075 |
@endcode |
|
2076 |
||
2077 |
Following code will fail: |
|
2078 |
@code |
|
2079 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2080 |
... |
|
2081 |
fm->Rename(_L("C:\\SRC\\ITEM01"), _L("C:\\TRG\\ITEM01")); |
|
2082 |
fm->Rename(_L("C:\\SRC\\ITEM*"), _L("C:\\TRG\\ITEM*")); |
|
2083 |
fm->Rename(_L("C:\\SRC\\"), _L("C:\\TRG\\")); |
|
2084 |
@endcode |
|
2085 |
||
2086 |
3. When renamnig a directory: |
|
2087 |
||
2088 |
3.1. Only when the trailing backslash ("\") is missing from the source path (aName), |
|
2089 |
will the source directory be renamed, otherwise, see rule 1.1. |
|
2090 |
||
2091 |
For example, following code will result in moving "C:\SRC" directory including all |
|
2092 |
its contents: |
|
2093 |
@code |
|
2094 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2095 |
... |
|
2096 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
2097 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\")); |
|
2098 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\*.*")); |
|
2099 |
@endcode |
|
2100 |
||
2101 |
3.2. Wildcards can not be used for moving directories; |
|
2102 |
||
2103 |
3.3. Overwriting is not permitted; |
|
2104 |
||
2105 |
For example, giving directory structure as following: |
|
2106 |
@code |
|
2107 |
C:\SRC\FILE.TXT |
|
2108 |
C:\TRG\ |
|
2109 |
C:\TRG\SRC\ |
|
2110 |
@endcode |
|
2111 |
||
2112 |
following code will fail: |
|
2113 |
@code |
|
2114 |
CFileMan* fm(CFileMan::NewL(iFs)); // Where iFs is an RFs handle |
|
2115 |
... |
|
2116 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG")); |
|
2117 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\")); |
|
2118 |
fm->Rename(_L("C:\\SRC"), _L("C:\\TRG\\*.*")); |
|
2119 |
@endcode |
|
2120 |
||
2121 |
4. Notes: |
|
2122 |
||
2123 |
4.1. The target and source directories must be on the same drive. |
|
2124 |
||
2125 |
4.2. Read-only, hidden and system files can be moved and the source file's |
|
2126 |
attributes are preserved in the target file, but open files cannot |
|
2127 |
be moved. Attempting to move an open file will return an error for |
|
2128 |
that file, as retrieved by CFileBase::GetLastError(). |
|
2129 |
||
2130 |
@param aName Path specifying the file(s) to be renamed. Any path components |
|
2131 |
which are not specified |
|
2132 |
here will be taken from the session path. |
|
2133 |
@param aNewName Path specifying the new name for the files and/or |
|
2134 |
the new directory. Any directories specified in this path |
|
2135 |
that do not exist, will be created. Any path components which |
|
2136 |
are not specified here will be taken from the session path. |
|
2137 |
@param aSwitches Specify zero for no overwriting; |
|
2138 |
CFileMan::EOverWrite to overwrite files with the same name. |
|
2139 |
This function cannot operate recursively. |
|
2140 |
||
2141 |
@return KErrNone if successful, otherwise one of the other system-wide error |
|
2142 |
codes. |
|
2143 |
||
2144 |
@see CFileBase::GetLastError() |
|
2145 |
||
2146 |
@capability Dependent If either aName or aNewName is /Sys then Tcb capability is required. |
|
2147 |
@capability Dependent If either aName or aNewName begins with /Private and does not match |
|
2148 |
this process' SID then AllFiles capability is required. |
|
2149 |
@capability Dependent If either aName or aNewName is /Resource then Tcb capability is required. |

|
2666 |
If the flag is set for no overwriting and the target file already exists, |
|
2667 |
then the target file will not be overwritten, and an error (KErrAlreadyExists) |
|
2668 |
will be returned. |
|
2669 |
Error codes may be retrieved using CFileBase::GetLastError(). |
