- Error codes
- Extracted file
Extracts all files from an archive and decompresses them. The archive used can be in CAB, RAR, ZIP, WDZ, 7z, TAR or TGZ (TAR.GZ) format.
Sintaxis
<Result> = <Archive>.Extractall([<Destination of files> [, <Options> [, <WLanguage procedure> [, <Progress>]]]])
<Result>: Integro - 0 if the files have been extracted,
- An error code (value greater than 0) otherwise. For more details on these error codes, see the Remarks.
<Archive>: Variable de tipo zipArchive Name of a variable of type zipArchive corresponding to the archive to use. <Destination of files>: Cadena de caracteres opcional o constante Destination path of extracted files:- Optional character string: The files are extracted into the specified path to which is added the tree structure of each file (the disk is not stored). The specified path is created if it does not exist.
- Optional constant:
| | | zipDirectory | Extraction into the current directory while restoring the tree structure of file (if it was stored). | | zipDrive | Extraction:- to the initial file location if it was stored and if the drive exists.
- while restoring the tree structure of the file on the current drive if the drive or the stored directory does not exist.
- into the current directory if only the file name and extension have been stored.
Remark: If the zipDrive constant is used, the WDZ format stores the full path of the file (including the drive letter) while the ZIP format does not store the drive letter.
Archives in 7z format: This constant and zipDirectory will have the same effect. | | zipOverwrite | During the extraction, the existing read-only files are automatically overwritten by the extracted files. This constant can be combined with the zipDrive and zipDirectory constants. |
<Options>: Constante opcional Configure the extraction (if <Destination of files> corresponds to a character string):
| | | zipOverwrite | During the extraction, the existing read-only files are automatically overwritten by the extracted files. |
<WLanguage procedure>: Nombre de procedimiento opcional Name of the WLanguage procedure that will be called if an error occurs when extracting files.
CAUTION: This parameter can be used only if <Archive> corresponds to a zipArchive variable.This procedure has the following format: PROCEDURE <Nom de la procédure>(<Code erreur>, <Nom du fichier>) where: - <Error code> is an integer corresponding to the code of the error that occurred when extracting the file.
- <File name> is a character string that contains the path of the file processed by .ExtractAll.
The procedure can return one of the following constants: | | | zipCancel | Cancels the extraction of files from the archive. | | zipIgnore | Ignores the file in error. | | zipRetry | Retries the file extraction. |
<Progress>: Nombre de control o nombre de Procedure Progress bar management mode. This parameter can correspond to: - the name of a WLanguage procedure. This procedure has the following format:
PROCEDURE <Nom de la procédure> (<Fichier en cours>, <Pourcentage d'avancement global>, <Pourcentage d'avancement du fichier>)
where: - <Current file> corresponds to the name of the file currently processed.
- <Global progress percentage> corresponds to the progress percentage of the extraction of files from the archive.
- <File progress percentage> corresponds to the progress percentage of the file being extracted from the archive.
If you are using an archive: - in TAR or TGZ (TAR.GZ) format, the progress bar is refreshed at the end of the extraction of each file.
- in CAB and RAR format, the progress bar is refreshed at the end of the extraction of each file.
- in 7z format, only <Overall progress percentage> is specified. <File progress percentage> will have the same value.
Observaciones Error codes The following error codes are returned: - 1: The path passed as parameter does not exist.
- 2: Access denied: the user has no sufficient rights.
- 3: The archive is corrupted.
- 4: The path does not exist in the archive.
- 6: The files of the sub-archives are not arranged in order (when extracting from a multi-part archive).
