It exposes the entry name, file type, size, ownership, permissions, timestamps, and server-provided attribute flags such as hidden, read-only, archive, immutable, encrypted, compressed, sparse, append-only, system, and synchronization status. It is typically used together with `Chilkat.SFtpDir` when iterating a remote directory and deciding how each entry should be displayed, filtered, downloaded, skipped, or processed. **Name and type** Read `Filename` and `FileType`, or use convenience flags such as `IsRegular`, `IsDirectory`, and `IsSymLink`. **File sizes** Access the entry size as a 32-bit integer, 64-bit integer, or decimal string using `Size32`, `Size64`, or `SizeStr`. **Timestamps** Inspect creation, last-access, and last-modified times as date/time values or RFC822-formatted strings when supported by the server. **Ownership** Read numeric user and group IDs, and when the server supports it, textual owner and group names. **Permissions** Inspect the POSIX-style permissions bit mask for read, write, execute, set-user-ID, set-group-ID, and sticky-bit information. **Extended attributes** Check server-provided flags such as hidden, read-only, archive, immutable, encrypted, compressed, sparse, append-only, system, and sync. **Common pattern:** Retrieve a directory listing with `Chilkat.SFtp`, iterate its `Chilkat.SFtpDir` entries, and populate a `Chilkat.SFtpFile` object for each item. Use the file type, timestamps, size, permissions, and attribute flags to decide whether the entry is a regular file, directory, symlink, or special item and how the application should handle it. **Server-version note:** Some metadata is only available from newer SFTP protocol versions. For example, textual owner/group information and creation time require SFTP v4 or later, while many extended attribute flags such as read-only, archive, immutable, compressed, encrypted, sparse, append-only, and system require SFTP v6 or later. ## Object creation, unlocking and error handling **Object Creation** ```java CkSFtpFile obj = new CkSFtpFile(); ``` Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in Java. How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called. ## Members common to every Chilkat class Documented once per language in `common-members.md`; listed here so this page is self-contained. | Property | Signature | Access | Meaning | |---|---|---|---| | `DebugLogFilePath` | `void get_DebugLogFilePath(CkString str); String debugLogFilePath(); void put_DebugLogFilePath(String newVal);` | read/write | If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. | | `LastErrorHtml` | `void get_LastErrorHtml(CkString str); String lastErrorHtml();` | read-only | Provides HTML-formatted information about the last called method or property. | | `LastErrorText` | `void get_LastErrorText(CkString str); String lastErrorText();` | read-only | Provides plain text information about the last called method or property. | | `LastErrorXml` | `void get_LastErrorXml(CkString str); String lastErrorXml();` | read-only | Provides XML-formatted information about the last called method or property. | | `LastMethodSuccess` | `boolean get_LastMethodSuccess(); void put_LastMethodSuccess(boolean newVal);` | read/write | Indicates the success or failure of the most recent method call: `true` means success, `false` means failure. | | `VerboseLogging` | `boolean get_VerboseLogging(); void put_VerboseLogging(boolean newVal);` | read/write | If set to `true`, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. | | `Version` | `void get_Version(CkString str); String version();` | read-only | Version of the component/library, such as "10.1.0" | ## Member index | Member | Kind | Signature | |---|---|---| | `CreateTimeStr` | property, read-only | `void get_CreateTimeStr(CkString str); String createTimeStr();` | | `Filename` | property, read-only | `void get_Filename(CkString str); String filename();` | | `FileType` | property, read-only | `void get_FileType(CkString str); String fileType();` | | `Gid` | property, read-only | `int get_Gid();` | | `Group` | property, read-only | `void get_Group(CkString str); String group();` | | `IsAppendOnly` | property, read-only | `boolean get_IsAppendOnly();` | | `IsArchive` | property, read-only | `boolean get_IsArchive();` | | `IsCaseInsensitive` | property, read-only | `boolean get_IsCaseInsensitive();` | | `IsCompressed` | property, read-only | `boolean get_IsCompressed();` | | `IsDirectory` | property, read-only | `boolean get_IsDirectory();` | | `IsEncrypted` | property, read-only | `boolean get_IsEncrypted();` | | `IsHidden` | property, read-only | `boolean get_IsHidden();` | | `IsImmutable` | property, read-only | `boolean get_IsImmutable();` | | `IsReadOnly` | property, read-only | `boolean get_IsReadOnly();` | | `IsRegular` | property, read-only | `boolean get_IsRegular();` | | `IsSparse` | property, read-only | `boolean get_IsSparse();` | | `IsSymLink` | property, read-only | `boolean get_IsSymLink();` | | `IsSync` | property, read-only | `boolean get_IsSync();` | | `IsSystem` | property, read-only | `boolean get_IsSystem();` | | `LastAccessTimeStr` | property, read-only | `void get_LastAccessTimeStr(CkString str); String lastAccessTimeStr();` | | `LastModifiedTimeStr` | property, read-only | `void get_LastModifiedTimeStr(CkString str); String lastModifiedTimeStr();` | | `Owner` | property, read-only | `void get_Owner(CkString str); String owner();` | | `Permissions` | property, read-only | `int get_Permissions();` | | `Size32` | property, read-only | `int get_Size32();` | | `Size64` | property, read-only | `long long get_Size64();` | | `SizeStr` | property, read-only | `void get_SizeStr(CkString str); String sizeStr();` | | `Uid` | property, read-only | `int get_Uid();` | Deprecated members are listed at the end of this file with their replacements; do not use them in new code. ## Properties ### SFtpFile.CreateTimeStr `Chilkat 11.7.0 · ckjava · SFtpFile · CreateTimeStr · property · read-only` ```java void get_CreateTimeStr(CkString str); String createTimeStr(); ``` Returns the file creation date and time as an RFC 822-formatted string, such as `Fri, 21 Nov 1997 09:55:06 -0600`. **Server requirement:** Creation-time metadata is available only when the server supports SFTP version 4 or later and provides this attribute. ### SFtpFile.Filename `Chilkat 11.7.0 · ckjava · SFtpFile · Filename · property · read-only` ```java void get_Filename(CkString str); String filename(); ``` Returns the name of the directory entry. Depending on the entry type, this may be a regular filename, directory name, symbolic-link name, or the name of another special filesystem object. ### SFtpFile.FileType `Chilkat 11.7.0 · ckjava · SFtpFile · FileType · property · read-only` ```java void get_FileType(CkString str); String fileType(); ``` Identifies the type of directory entry. The returned value is one of the following: | Value | Meaning | | :--- | :--- | | `regular` | A regular file. | | `directory` | A directory. | | `symLink` | A symbolic link. | | `special` | A special file whose more specific type is not reported. | | `unknown` | The type is unknown or was not provided by the server. | | `socket` | A socket. | | `charDevice` | A character device. | | `blockDevice` | A block device. | | `fifo` | A FIFO (named pipe). | The convenience properties `IsRegular`, `IsDirectory`, and `IsSymLink` may be used for the most common entry types. ### SFtpFile.Gid `Chilkat 11.7.0 · ckjava · SFtpFile · Gid · property · read-only` ```java int get_Gid(); ``` Returns the numeric group ID associated with the file. ### SFtpFile.Group `Chilkat 11.7.0 · ckjava · SFtpFile · Group · property · read-only` ```java void get_Group(CkString str); String group(); ``` Returns the textual group name associated with the file. **Server requirement:** This attribute is available only when the server supports SFTP version 4 or later and provides owner/group names. ### SFtpFile.IsAppendOnly `Chilkat 11.7.0 · ckjava · SFtpFile · IsAppendOnly · property · read-only` ```java boolean get_IsAppendOnly(); ``` Returns `true` if the server marks the file as append-only. New data may be added only at the end of the file; existing data cannot be overwritten through normal file writes. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsArchive `Chilkat 11.7.0 · ckjava · SFtpFile · IsArchive · property · read-only` ```java boolean get_IsArchive(); ``` Returns `true` if the server marks the file for inclusion in backup or archive operations. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsCaseInsensitive `Chilkat 11.7.0 · ckjava · SFtpFile · IsCaseInsensitive · property · read-only` ```java boolean get_IsCaseInsensitive(); ``` Applies to directories. Returns `true` when names within the directory should be compared without regard to letter case. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsCompressed `Chilkat 11.7.0 · ckjava · SFtpFile · IsCompressed · property · read-only` ```java boolean get_IsCompressed(); ``` Returns `true` if the file is stored using transparent filesystem-level compression on the server. This attribute describes how the server stores the file. It does not change the file bytes transferred through SFTP. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsDirectory `Chilkat 11.7.0 · ckjava · SFtpFile · IsDirectory · property · read-only` ```java boolean get_IsDirectory(); ``` Returns `true` if the directory entry is a directory. ### SFtpFile.IsEncrypted `Chilkat 11.7.0 · ckjava · SFtpFile · IsEncrypted · property · read-only` ```java boolean get_IsEncrypted(); ``` Returns `true` if the file is stored using transparent filesystem-level encryption on the server. This attribute describes storage at rest. It does not alter the file bytes returned by read operations or accepted by write operations. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsHidden `Chilkat 11.7.0 · ckjava · SFtpFile · IsHidden · property · read-only` ```java boolean get_IsHidden(); ``` Returns `true` if the server marks the entry as hidden. Hidden entries are normally omitted from user-facing displays unless the user specifically requests them. ### SFtpFile.IsImmutable `Chilkat 11.7.0 · ckjava · SFtpFile · IsImmutable · property · read-only` ```java boolean get_IsImmutable(); ``` Returns `true` if the server marks the file as immutable. An immutable file cannot normally be deleted, renamed, modified, or used as the target of a new hard link. Immutability is generally stronger than read-only status, the ordinary permission mask, or an access-control list. On many systems, only a privileged administrator can set or clear this attribute. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsReadOnly `Chilkat 11.7.0 · ckjava · SFtpFile · IsReadOnly · property · read-only` ```java boolean get_IsReadOnly(); ``` Returns `true` if the server marks the file as read-only. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsRegular `Chilkat 11.7.0 · ckjava · SFtpFile · IsRegular · property · read-only` ```java boolean get_IsRegular(); ``` Returns `true` if the directory entry is a regular file rather than a directory, symbolic link, device, socket, FIFO, or other special type. ### SFtpFile.IsSparse `Chilkat 11.7.0 · ckjava · SFtpFile · IsSparse · property · read-only` ```java boolean get_IsSparse(); ``` Returns `true` if the server identifies the file as sparse. A sparse file can contain unwritten regions, often called holes, that read as zero bytes without consuming equivalent physical disk space. For example, writing data at an offset of 10 MB may leave the region between the previous end of file and that offset unallocated on disk. Some servers store all files sparsely and may always set this flag. Other servers cannot reliably determine whether a file is sparse, so a file may be sparse even when this property is `false`. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsSymLink `Chilkat 11.7.0 · ckjava · SFtpFile · IsSymLink · property · read-only` ```java boolean get_IsSymLink(); ``` Returns `true` if the directory entry is a symbolic link. ### SFtpFile.IsSync `Chilkat 11.7.0 · ckjava · SFtpFile · IsSync · property · read-only` ```java boolean get_IsSync(); ``` Returns `true` if modifications to the file are committed synchronously to server storage. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.IsSystem `Chilkat 11.7.0 · ckjava · SFtpFile · IsSystem · property · read-only` ```java boolean get_IsSystem(); ``` Returns `true` if the server marks the file as part of the operating system. **Server requirement:** This attribute is defined for SFTP version 6 or later. ### SFtpFile.LastAccessTimeStr `Chilkat 11.7.0 · ckjava · SFtpFile · LastAccessTimeStr · property · read-only` ```java void get_LastAccessTimeStr(CkString str); String lastAccessTimeStr(); ``` Returns the file's last-access date and time as an RFC 822-formatted string, such as `Fri, 21 Nov 1997 09:55:06 -0600`. ### SFtpFile.LastModifiedTimeStr `Chilkat 11.7.0 · ckjava · SFtpFile · LastModifiedTimeStr · property · read-only` ```java void get_LastModifiedTimeStr(CkString str); String lastModifiedTimeStr(); ``` Returns the file's last-modified date and time as an RFC 822-formatted string, such as `Fri, 21 Nov 1997 09:55:06 -0600`. Use `LastModifiedTime` when a native date/time value is more convenient. ### SFtpFile.Owner `Chilkat 11.7.0 · ckjava · SFtpFile · Owner · property · read-only` ```java void get_Owner(CkString str); String owner(); ``` Returns the textual owner name associated with the file. **Server requirement:** This attribute is available only when the server supports SFTP version 4 or later and provides owner/group names. ### SFtpFile.Permissions `Chilkat 11.7.0 · ckjava · SFtpFile · Permissions · property · read-only` ```java int get_Permissions(); ``` Returns the POSIX-style file-permission bit mask. The values correspond to the permission and special-mode bits in the POSIX `st_mode` field. | Symbol | Octal value | Meaning | | :--- | :--- | :--- | | `S_IRUSR` | `0400` | Owner read | | `S_IWUSR` | `0200` | Owner write | | `S_IXUSR` | `0100` | Owner execute | | `S_IRGRP` | `0040` | Group read | | `S_IWGRP` | `0020` | Group write | | `S_IXGRP` | `0010` | Group execute | | `S_IROTH` | `0004` | Others read | | `S_IWOTH` | `0002` | Others write | | `S_IXOTH` | `0001` | Others execute | | `S_ISUID` | `4000` | Set-user-ID | | `S_ISGID` | `2000` | Set-group-ID | | `S_ISVTX` | `1000` | Sticky bit | Use bitwise AND operations to test individual permission bits. ### SFtpFile.Size32 `Chilkat 11.7.0 · ckjava · SFtpFile · Size32 · property · read-only` ```java int get_Size32(); ``` Returns the file size in bytes as a 32-bit integer. Returns `-1` when the size cannot be represented by a 32-bit integer. Use `Size64` or `SizeStr` for larger values. ### SFtpFile.Size64 `Chilkat 11.7.0 · ckjava · SFtpFile · Size64 · property · read-only` ```java long long get_Size64(); ``` Returns the file size in bytes as a 64-bit integer. ### SFtpFile.SizeStr `Chilkat 11.7.0 · ckjava · SFtpFile · SizeStr · property · read-only` ```java void get_SizeStr(CkString str); String sizeStr(); ``` Returns the file size in bytes as a base-10 string. This is the string representation of `Size64` and is useful in environments where a 64-bit integer is inconvenient or unavailable. ### SFtpFile.Uid `Chilkat 11.7.0 · ckjava · SFtpFile · Uid · property · read-only` ```java int get_Uid(); ``` Returns the numeric user ID associated with the file. ## Deprecated members — do not use in new code | Member | Kind | Deprecated in | Use instead | |---|---|---|---| | `GetCreateDt` | method | before 11.6.1 | — | | `GetLastAccessDt` | method | before 11.6.1 | — | | `GetLastModifiedDt` | method | before 11.6.1 | — |
